1 INTRODUCTION INTRODUCTION This manual describes the 5740X-400/401 Strider Speed Control, and is intended to be a guide in the installation and operation of the control. This first section, the INTRODUCTION, describes the features of the Strider, its applications, and how it operates. Next comes the INSTALLATION section that goes into detail on wiring and programming. Following the INSTALLATION section is the RUN section, which describes what the operator can get out of the Strider, and how he should put things into the Strider. The final sections are TROUBLESHOOT- ING, SPECIFICATIONS, and DIMENSIONS. Optional System Control Logic The Strider's job is to control the speed of a motor by adjusting the voltage speed input to an AC, DC, or servo-type variable speed drive. This is typically done in a closed-loop system by comparing a feedback input to a calculated reference speed and tweaking the Strider's analog output voltage to the drive. The two modes of operation for the Speed Control are the Master Mode and the Follower mode. In the Master mode, the user enters a speed preset ad the control adjusts the analog output to have the motor reach and maintain this speed. Figure 1 illustrates the Master Mode. Ext. Reference Input Feedback Input Speed Control Variable Speed Motor Follower Speed Control for Process or System Variable Speed Drive System can be made up of DC, AC, or Servo type components.

Master Mode Master Speed Control for Process or System Variable Speed Drive System can be made up of DC, AC, or Servo type components. Variable Speed Motor The Follower mode uses the same "parts" as the Master mode plus an external reference input. This is a speed input from a master motor. The user enters a speed preset as a percentage of follower speed to master speed. Figure 2 illustrates the Follower mode. Strider Features and Terminology Preset - commonly known also as "setpoint". This is the speed value entered by the operator to which the Strider will control the motor. In the master mode, presets are rate values, such as motor RPM, conveyor feet per minute, pump gallons per minute, etc. In the follower mode, presets are ratios of the speeds of the follower motor to the master motor. Presets may be normal or inverse. Most users will employ normal presets, in which there is a direct relationship between the preset and motor speed - the higher the preset, the faster the motor turns. Some applications, such as baking time, will go with the inverse preset approach. In this case, the Strider does its arithmetic "upside-down" and the higher the preset entered, the slower the motor turns. Scaling - units conversion. The Strider calculates how fast the motor should be turning and how fast it really is turning in units of RPM. In many master mode application, and all follower mode applications, the operator must be able to enter presets in other types of units. Also, the operator may want to view the speed of the process in units other than 1

2 INTRODUCTION continued motor RPM. Scaling arithmetically converts motor RPM into preset and speed units that make sense to the operator. Proper scaling values used during initial programming are essential to the predictable and responsive operation of the control. The scaling process is covered in detail in the installation section of this manual. Feedback - the pulsed, frequency signal produced by a sensor driven directly or indirectly by the motor. The Strider compares the feedback speed to the speed it has calculated that the motor should run. If there is a difference, the Strider adjusts its output until the difference is zero. The feedback signal is necessary for closed-loop operation. Ramped Reference - the calculated value in RPM at which the motor should run. This is calculated based on the operator entered preset and also in the follower mode, the speed of the master motor. Error - the difference between ramped reference speed and feedback speed. The Strider uses proportional - integral (PI) error correction to reduce the error to zero. Speed - the speed displayed to the operator is either a scaled conversion of feedback RPM or, optionally in follower mode, the ratio of follower motor to master motor. If presets are selected to be inverse, the speed will also be calculated inversely. Generally, the speed will be displayed in the same units as the preset, letting the operator know that the process is running at the preset speed. External Reference - the pulsed, frequency signal produced by a sensor driven directly or indirectly by the master motor. The follower motor speed, which is calculated by the Strider, depends upon the speed of the master motor and the preset entered by the operator. The external reference signal is used only when the Strider is in the follower mode. Ratio - follower mode presets are determined by taking the ratio of follower speed to master speed. Also, the speed displayed to the operator is usually chosen as the ratio of feedback speed to master speed. Drive Signal - the Strider calculates a ramped reference speed, in RPM, at which the motor should run. The Strider must then calculate the percentage of its analog output voltage required to get the motor to that speed. This number, in percent, is called drive signal. The drive signal is sent to the digital-to-analog converter (DAC) where it is converted into an output voltage in the range of 0-10 VDC. Models There are two models of the Strider, the basic 5740X-400 and the 5740X-401, which does everything the -400 does and: 1. The -401 has two speed presets; the -400 has one. 2. The -401 has reversing capability; it can switch the polarity of its output to an appropriate drive to cause the motor to reverse The 0-10 VDC output of the -401 is adjustable down to 0-3 VDC. 4. The -400 has four control inputs; the -401 has twelve. The additional inputs give the -401 more I/ O flexibility. A detailed I/O comparison is made below. Control Inputs Model 5740X-400 of the Speed Control has four control inputs. Two of these inputs are fixed (START, RAMPED STOP) and two inputs are programmable with six options for each. These options are JOG OPEN LOOP FAST STOP LOCK ALL LOCK PROGRAM DISABLED Model 5740X-401 has 12 control inputs. Eight inputs have fixed functions. START RAMPED STOP JOG OPEN LOOP FAST STOP PRESET ECT INCREMENT PRESET DECREMENT PRESET The other four inputs are programmable with seven options for each one. REVERSE HOLD SPEED UNLATCH ALARM INHIBIT LOW ALARM LOCK PROGRAM LOCK ALL DISABLED All control inputs are activated when they are tied to DC common. This can be done directly with a wire jumper, contact closure, or an NPN sensor. Outputs Both models of the Speed Control have four NPN opencollector transistor outputs. These outputs can each be assigned one of seven functions. ERROR ALARM NO FEEDBACK LOW SPEED ALARM, FOLLOWS HIGH SPEED ALARM, FOLLOWS ZERO SPEED AT SPEED DISABLED

4 INTRODUCTION continued Theory of Operation / Arithmetic Diagnostic Setup Master Pulse External Reference Scaling REF Setup Follower Setup Jog Setup Or RS Ramp and Limit Control Reference Processing RRS Speed Regulator Control FDBK DS DAC DS 0-10V Motor, Drive, and Load System Speed Out Reference Setup Modes Feedback Scaling Pulse Encoder or Sensor The Speed Control operates every five milliseconds, measuring input speed(s), reading the control inputs, adjusting outputs, and regulating the DAC output to control motor speed. The Strider can be operated in four modes: 1. Master 2. Follower 3. Jog 4. Diagnostic (force) The diagnostic setup is an open loop test mode that will be explained later in this section. The other three setups produce a reference speed (RS) in RPM. The reference speed is calculated by the Strider. Each setup uses a different formula to calculate reference speed; each calculation depends upon programmed parameters and the preset or preset and master motor speed. The abbreviations used in this section are: RS P MAX PST FDBK MAX FDBK REF MAX REF J Reference Speed (RPM) Preset (user units) Maximum Preset (user units) Feedback (RPM) Maximum Feedback (RPM) External Reference Speed (RPM) Maximum External Reference Speed (RPM) Jog Preset (RPM) Reference Speed Calculations (RS) Master Mode RS = RS = P MAX PST MAX PST P Follower Mode RS = REF MAX REF MAX FDBK MAX FDBK P MAX PST for normal presets for inverse presets MAX FDBK for normal presets REF MAX PST RS = MAX FDBK for inverse presets MAX REF P Jog Mode RS = J Ramped Reference Speed (RSS) Once RS is determined, the Strider applies four limitations to this speed. The ramp and limit control block massage RS into ramped reference speed (RSS) by considering: 1. Minimum limit. 2. Maximum limit. 3. Accel time. 4. Decel time. 4

5 INTRODUCTION continued RS Max Min Limit Control LIMIT CONTROL Input RS Maximum Limit Minimum Limit RAMP CONTROL Accel Time INPUTS Starts Ramped Stop Reverse Jog Hold Speed OUTPUTS At Speed Reversed Decel Time RRS The limit control section uses the maximum and minimum limit RPM parameters to modify the reference signal (RS). If RS is less than the minimum limit RPM, the minimum limit value is sent to the ramp control. If RS is greater than the maximum limit RPM, the maximum limit is sent to the ramp control. The minimum limit is not active in the jogging state. Ramp Control The ramp generator produces the ramped reference speed (RRS) by using the acceleration time and deceleration time parameters to alter the reference speed (RS). The acceleration time, deceleration time, and maximum feedback RPM values are used to calculate linear acceleration limits for RS. The ramp generator operates every five milliseconds to produce a smooth ramp from the old RS value to the new one. Drive Signal (DS) The speed regulator control block closes the control loop by comparing the calculated motor speed (RRS) to the actual motor speed (FDBK). The difference, in RPM, between the two speeds is called error. Using PI (proportional/integral) compensation, the Strider increases or decreases its output signal to reduce the error to zero. The amount of increase or decrease to the RRS is called trim. The corrected speed (RRS plus trim) is called drive signal (DS). DS is displayed as a percent, determined by: 0-10V Out RRS + TRIM MAX FDBK = DS 87.5 The DS is transmitted to an isolated digital-to-analog converter (DAC), which puts out 0-10Vdc to the drive. The voltage out (V) is determined by: DS V = (10V) 100 Diagnostic Mode The diagnostic mode allows the user to enter a DS value directly. This is a force mode that is a useful setup tool. The feedback RPM is displayed during the time that the DS is applied to the DAC, but no RRS is calculated, and no error correction is made. Acceleration and Deceleration Times The ramp generator uses these parameters to generate linear (straight-line) acceleration that is applied whenever RS changes (starting, stopping, reversing, changing presets, change in external reference speed, etc.). These parameters are defined as the time to go from zero speed to the maximum feedback RPM or vice versa. Use the following equations to calculate intermediate acceleration times. new RS - old RS time = MFB - 0 accel time old RS - new RS time = MFB - 0 decel time 5

8 INSTALLATION continued MODULAR COMMUNICATION JACK The RJ-11 modular telephone jack is an alternate method of hooking up a serial communications line. Pin 2 of the jack is negative and is the same as terminal 22. Pin 3 is positive and is the same as terminal 21. Pins 1 and 4 are connected to DC Common and should be used for any shield connections. Note: This jack is intended for connection to Ambassador and other RS-485 communication networks only. It should not be connected to any telephone system as damage or hazard may result. TERMINAL BLOCKS Connections to the control are made through removable, screw terminal blocks to allow for ease of wiring and removal. The terminals can accommodate stranded, solid, or fused wire from 14 to 22 gauge. To remove the terminal block, disconnect power and gently pry underneath each end with a small screwdriver. Press straight on to re-install. GENERAL WIRING PRACTICES 1. Disconnect all power before wiring terminals. A safety hazard exists if this precaution is not observed. Treat all control and count inputs as hazardous since they may carry line voltage. 2 Use shielded cables for frequency signals, control input, drive signal and communications signals. Connect shield to common (terminal 2, 3 or 4) of Speed Control to terminate properly. 3. Keep all signal lines as short as possible. 4. Do NOT bundle or route signal lines with power or machine control wiring. Use separate conduit for power and signal wires. Route Drive Signal separately. 5. Provide "clean" power to the speed control. In severe cases, power may have to be filtered or a separate power source used. Do not use the same power source that is supplying the loads. 6. Use 18 ga. minimum (0.97mm 2, 600V) and 14 ga. maximum (2.1mm 2, 600V) wire for AC power wiring. 7. See page 9, top drawing, for the correct fuse to be used in the power input wiring. DIP SWITCH FUNCTIONS Switch 1: Feedback input sink / source Off: Feedback input requires a current sourcing input signal. On: Feedback input requires a current sinking input signal. Switch 2: External Reference input sink / source Off: External Reference requires a current sourcing input signal. On: External Reference requires a current sinking input signal. Switch 3: Feedback Input threshold level Off: high threshold level use with DC sensors. On: low threshold level use with mag pickups. Turn switch 1 off. Switch 4: External Reference threshold level Off: high threshold level use with DC sensors. On: low threshold level use with mag pickups. Turn switch 2 off. Dip switches may be set through an opening on the bottom of the unit. It is located towards the rear of the control. PANEL MOUNTING The panel mounting kit includes: (1) mounting gasket, (2) mounting clips and (4) screws. Refer to the dimension diagram on page 47 for a drawing of the correct installation of these parts. The mounting gasket is coated on one side with a contact adhesive and a paper backing. Care should be taken during the gasket installation that the gasket be correctly positioned on the panel at the first attempt. Attempting to re-position the gasket once the adhesive has come in contact with the panel is likely to deform or tear the gasket. This may result in an improper seal. For best results, follow these directions: 1. Stand the Speed Control counter on a desk or table with its display down, screw terminals up. 2. Remove and discard the center square of the gasket at the scribe marks in the gasket and paper backing. Do not remove the backing from the remaining outer rim. 3. Slide the gasket down the unit until it is in position at the rear of the unit's front bezel. The paper backing side should be up. 4. Insert the tip of a knife between the paper and the gasket and, while holding the gasket down to the unit with the knife, peel off the paper backing. 5. Slide the unit through the panel cutout until the gasket firmly adheres to the panel. 6. Install the mounting clips and screws as shown in the diagram on page 39. Do not overtighten the mounting screws. The screws should be tight enough to firmly hold the unit in place, but not so tight as to squeeze the gasket out from behind the front bezel. 7. A switch shall be included in the building installation: It shall be in close proximity to the equipment and within easy reach of the operator. It shall be marked as the disconnecting device for the equipment. Switches and circuit breakers in Europe must comply with IEC

SERIAL COMMUNICATIONS The serial communications capability of the speed control allows a host computer to monitor all unit parameters. All setup parameters can be read and programmed through serial communications. Most of the control input functions are available through serial communications. In addition, the output states and several internal states can be read through the serial port. The speed control serial communications are based on the RS-485 specification and conform to Opto-22 protocol. A separate document describing the serial communications characteristics is available from Eaton Corporation. If you would like a copy of the communications manual, call the Literature Department at 1/

12 INSTALLATION continued Programming This section of the manual presents the programming choices available to the user. Programming gives the Strider the personality to perform a specific application. The Strider is a versatile control, but most users will not use all its features. Those users who are familiar with the Strider's features and terminology may wish to go directly into the program mode. All users are invited to browse the final entry of this section - System Considerations. It provides insight into the programming aspects of scaling, tuning, operator access, etc. Finally, the programming choices for the Strider's serial communication port are given, but the serial format, command list, and programming indices are not. Detailed information is available in a separate manual that can be obtained by calling Cutler-Hammer (Durant) at New users are advised that the somewhat cryptic program menu choices are defined in the section "Description of Program Options" (pp 19-22), following the program menu.

The speed displayed is a scaled rate of feedback motor speed (normal preset) or a scaled time value (inverse preset). FOLLOWER SP = SPEED - the motor is controlled to a speed that is dependent upon the operator-entered preset and the master motor speed. The speed displayed is a scaled rate of follower motor speed (normal preset) or a scaled time value (inverse preset). FOLLOWER SP= RATIO - the motor is controlled to a speed that is dependent upon the operator-entered preset and the master motor speed. The speed displayed is either a ratio of follower motor speed to master motor speed (normal preset) or master motor speed to follower motor speed (inverse preset). MAX PST - the maximum preset is the preset value that causes the motor to run at maximum feedback RPM. This is an important number for proper scaling. To determine this number, see the section on Scaling, P 23. If you choose a value that is less than an existing preset (for normal preset), the value will not be accepted and the display will read VALU<PST for three seconds. If you choose a value that is greater than an existing preset (for inverse preset), the value will not be accepted and the display will read VALU>PST for three seconds. P UNITS - the engineering units that describe the preset can be entered here and displayed on the Maximum Preset screen and on the two preset editing screens in the Adjust Menu. MAX SPD - the maximum speed is the value that is shown on the speed display when the motor is at maximum feedback RPM. This value scales the speed display. SP UNITS - the engineering units that describe the displayed speed (either speed or ratio) can be entered here. MIN LMT - the programmed Minimum Limit value sets the lower limit of the Reference Speed. This lower limit is disregarded at startup until after the Ramped Reference Speed has reached or exceeded the Minimum Limit. The range is from 0 to the MAX LMT value. MAX LMT - the programmed Maximum Limit value sets the upper limit of the Reference Speed. The range is from the MIN LMT to PROGRAM FEEDBACK INPUT (FDBK IN) FDBK IN - enter the pulse per revolution ratio of the feedback sensor. MAX FDBK - the maximum feedback value represents the RPM of the motor at a particular value of the drive signal, either 87.5% or 100%. Max feedback is an important number for proper scaling and is the first scaling value to be determined. See the section on Scaling, P 23. If you choose a value that is less than an existing jog preset, the value will not be accepted and the display will read VALU<PST for three seconds. 0 SPEED TIME - enter the amount of time between Feedback input pulses that must elapse before the speed is considered to be zero. This time-out value will be used whenever the Ramped Reference Speed is zero. A Zero Speed output will turn on when this time has elapsed. NO FDBK F STOP - this causes the Speed Control to enter the Fast Stop mode when no Feedback pulses have been received for the programmed No Feedback Time and the Drive Signal is greater than 25%. NO FDBK NO ACT - no action occurs when no Feedback pulses have been received for the programmed No Feedback Time. NO FDBK TIME - the no feedback time is the amount of time that must elapse between feedback pulses before the control will recognize the no feedback condition. The no feedback condition can cause the control to fast stop, or trigger an output, or both MAX FB = 87.5% DS - this is the normal choice for most drives. The Maximum Feedback RPM value corresponds to 87.5% of the Drive Signal Reference voltage. This choice allows about 14% overhead so that the Speed Control can momentarily force DC drives to increase the motor voltage when the motor response is too slow. MAX FB = 100% DS - this is a special choice for some AC adjustable frequency (AF) drives. The Maximum Feedback RPM value corresponds to the Drive Signal Reference voltage. On an AF drive the maximum input voltage corresponds to the maximum drive frequency, and the AF drive will not provide any extra boost in frequency for a higher Drive Signal voltage. 19

20 INSTALLATION continued PROGRAM FREQUENCY INPUT (FREQ IN) Note: the PROGRAM FREQ IN menus appear only if the Speed Control is in the follower mode. REF IN - enter the pulse per revolution ratio of the master motor (external reference) sensor. MAX REF - the maximum external reference value corresponds to the RPM of the master motor when the follower motor is at maximum feedback RPM and the preset is set to the maximum preset value. Maximum reference is an important number for proper scaling; see Scaling, P 23. PROGRAM INPUTS FOR 5740X-400 Note: For Model 5740X-400 the four control inputs are assigned the following functions: 1 START 2 RAMPED STOP 3 Programmable Function 4 Programmable Function Programmable Functions: DISABLED JOG LOCK PROGRAM LOCK ALL FAST STOP OPEN LOOP PROGRAM INPUTS FOR 5740X-401 NOTE: For Model 5740X-401 the 12 control inputs are assigned to following functions: 1 START 2 RAMPED STOP 3 JOG 4 OPEN LOOP 5 FAST STOP 6 INCREMENT PRESET 7 DECREMENT PRESET 8 PRESET ECT 9 Programmable Function 10 Programmable Function 11 Programmable Function 12 Programmable Function Programmable Functions: DISABLED HOLD SPEED REVERSE LOCK PROGRAM LOCK ALL UNLATCH ALARMS INHIBIT LOW ALARMS Note: The two following menus appear on Model 5740X-401 only. 1st PST STEP - The currently selected preset will change by this programmed amount each time the INCREMENT PRE- SET or DECREMENT PRESET is momentarily activated. The range is 0 to 199. RPT PST STEP - The currently selected preset will repeatedly change by this programmed value every 0.2 seconds whenever the INCREMENT PRESET or DECREMENT PRE- SET input is activated for more than 0.5 seconds. The range is 0 to 199. DISABLED - the input performs no function when activated. JOG - Activate this input to cause the Speed Control to enter the jogging state. The RAMPED STOP and FAST STOP inputs must be on and the START input must be off in order to enter the jogging state. LOCK PROGRAM (PGM) - connect this input to DC Common to inhibit access to the Program mode from the frontpanel keypad and from the serial port. Keyboard and serial diagnostic modes are also inhibited. All Run mode items can be accessed. LOCK ALL - activate this input to eliminate all operator access to both program mode and run mode options. FAST STOP (/F STOP) - deactivate this input to cause the motor to stop immediately. This input must be on to allow the motor to resume running. This input is usually used with a normally closed switch. OPEN (OPN) LOOP - this option is intended for system calibration and diagnostics. When activated, the Speed Control adjusts the Drive Signal output according to the Reference Speed only, and ignores the Feedback signal. HOLD SPEED (SPD) - activate this input to cause the Speed Control to maintain the current Ramped Reference Speed and ignore any attempts to change this speed. When this input is turned off the control will again change the speed according to the preset value and/or External Reference Speed. Deactivating the fast stop input always overrides hold speed. Deactivating ramped stop, even momentarily, will cause a ramped stop after the hold speed input is removed. A momentary ramped stop can be cancelled by a start input. REVERSE - in its normal state (off), this input allows a positive speed command voltage. When activated, the control will supply a negative voltage. If this input is turned on while the unit is in the motor-running mode, the Speed Control will cause the motor to decelerate to zero at the rate programmed in the Deceleration Time, and then accelerate in the opposite direction at the rate programmed in the Acceleration Time. 20

21 INSTALLATION continued Note: Do not use the REVERSE input if your motor drive does not allow motor reversing by a negative voltage. UNLATCH ALARMS (UNL ALM) - turn this input on to unlatch any Feedback Alarm output and the No Feedback output. When this input is turned off, these outputs will be allowed to turn on again the next time the Feedback speed is sampled. INHIBIT LOW ALARMS (INH LOW) - activate this input to hold the Feedback Low Alarm in the off state. Turn the Inhibit Low input off to allow the low alarm to again be operational. PROGRAM OUTPUTS Note: Reversed, High Alarm Latched, and Low Alarm Latched are not available in model Aside from that, each of the four digital control outputs can be assigned any of the following options. The conditions that control the outputs are evaluated every five milliseconds. DISABLED - the output will remain in the off, or unlatched, condition when programmed for this option. ZERO (0) SPEED - this output is on when the Ramped Reference Speed is zero and no Feedback pulses have been received for the programmed Zero Speed time. AT SPEED - this output is on when the control is in the motorrunning state and the Ramped Reference Speed equals the Reference Speed. REVERSED - this output turns on when two conditions are met: The Reverse Input is on The Drive Signal voltage is less than or equal to zero. NO FEEDBACK (FDBK) - this output is on when the Ramped Reference Speed is greater than zero and no Feedback pulses have been received for the programmed No Feedback time. ERROR (ER) ALARM - this output turns on when the error value is outside of the programmed allowable error limits. HIGH ALARM FOLLOWS (HI ALM FOLL) - this output turns on when the Feedback Speed becomes greater than or equal to the programmed High Alarm value. If the Feedback Speed returns below the High Alarm value, this output will turn off. Thus, the output "follows" the alarm condition. HIGH ALARM LATCHED (HI ALM LTCH) - this output turns on when the Feedback Speed becomes greater than or equal to the programmed High Alarm value. This output remains on (latched) even if the Feedback Speed returns below the High Alarm value. The Unlatch Alarms control input will turn this output off. LOW ALARM FOLLOWS (LOW ALM FOLL) - this output turns on when the Feedback Speed becomes less than or equal to the programmed Low Alarm value. If the Feedback Speed returns above the Low Alarm value, this output will turn off. Thus, the output "follows" the alarm condition. LOW ALARM LATCHED (LOW ALM LTCH) - this output turns on when the Feedback Speed becomes less than or equal to the programmed Low Alarm value. This output remains on (latched) even if the Feedback Speed returns above the Low Alarm value. The Unlatch Alarms control input will turn this output off. Note: The following menus appear only when a control output is programmed as a High or Low alarm. FDBK ALM HI/LOW - this option allows you to enter high and low feedback alarm setpoints directly into the Adjust Alarms menu. FDBK ALM NOM/DIFF - this option allows you to program the high and low Feedback Speed alarms by specifying a nominal speed value and a tolerance range of speeds that will not turn on the alarms. The first Feedback alarm value in the Adjust Alarms menu will become the nominal speed value and the second will become the difference offset above and below the nominal speed. The high alarm setpoint will be the nominal RPM value plus the difference RPM. The low alarm setpoint will be the nominal RPM value minus the difference RPM. If the low alarm setpoint is negative, the low alarm is disabled. FDBK ALM NOM/% - this option allows you to program the high and low Feedback Speed alarms by specifying a nominal speed value and a tolerance range of speeds that will not turn on the alarms. The first Feedback alarm value in the Adjust Alarms menu will become the nominal speed value and the second will become the percentage tolerance above and below the nominal speed. The high alarm setpoint will be the nominal RPM value plus the percentage of nominal RPM. The low alarm setpoint will be the nominal RPM value minus the percentage of nominal RPM. PROGRAM DISPLAY ALARMS HIDE/SHOW - Select HIDE to prevent access to the Alarm Adjust menu. Select SHOW to allow access to this menu. Note that the Adjust Alarms screen will show up only if an output has been programmed to one of the alarm types. SETUP HIDE/SHOW - Select HIDE to prevent access to the Adjust Setup menu. Select SHOW to allow access to this menu. 21

22 INSTALLATION continued TUNING HIDE/SHOW - Select HIDE to prevent access to the Adjust Tuning menu. Select SHOW to allow access to this menu. MON VAL HIDE/SHOW - Select HIDE to prevent access to the Monitor Values menus. Select SHOW to allow access to these menus. PROGRAM SERIAL PORT SERIAL (SER) PORT ID - Enter a two-digit serial port identification number form 00 to 99 decimal. All serial communications to this Speed Control must contain this ID number in hexadecimal. BAUD - Enter the desired serial port transmit and receive baud rate. Choices are 19200, 9600, 4800, 2400, 1200 and 300. TRANSMIT (Tx) DELAY - Enter a transmission delay of either 2 milliseconds or 100 milliseconds. The Speed Control waits for the selected time period before responding to any serial commands. This delay is provided to allow the host computer to switch from transmit to receive mode. SERIAL CONTROL (SER CTRL) DISABLED - The serial input of WSI and RSI commands will have no effect. The control inputs are active. SER CTRL ENABLED - The serial input of WSI or RSI commands is allowed. The control inputs are active. SER CTRL ONLY - The serial input of WSI or RSI commands is allowed. The control inputs are not active, except for the FAST STOP, UNLATCH ALARMS, INHIBIT LOW ALARM, LOCK PROGRAM, and LOCK ALL inputs. RDV DATA - This screen displays the model type of the Speed Control and its hexadecimal SERIAL PORT ID, as shown on page 18. This data is the response to the RDV command. SYSTEM CONSIDERATIONS This section of the manual is intended to provide practical information on several key concepts to the installer. Note that this manual starts with an introduction and description of the control, then goes into installation. The installation section begins with wiring, and the minimum wiring requirements (AC power, sensor input(s), start and stop inputs, 0-10V output to the drive) are generally well understood by installers. Next follows the rather lengthy program menu, and even with the definitions following the menu, an installer may wonder where to begin. The following topics are presented informally, with the intention of providing practical installation guidance. 2. Scaling - a step-by-step approach to determining your "Max" values. Proper scaling is essential responsive performance, yet too many people don't understand how to pick these values. Scaling does make sense and there is a method to the apparent "madness". 3. VALU>PST error message - it may appear while programming the Max Preset value when presets are inverse. 4. Setup and tuning - once the control is installed, accel and decel times can be determined, and the tuning process can begin. 5. Operator access - how much information should the operator get from the Strider, and what should be locked out? DIRECT DRIVE SIGNAL CONTROL - TEST MODE For a quick visual reference of what is going to happen as you explore this feature, turn back to the block diagram shown on page 4. Note that the diagnostic setup is directly connected to the DAC block. Also note that when the motor is running, the sensor signal goes into the Strider's feedback scaling block. You are probably now thinking that if the Strider had a screen where you could directly set the drive signal out and read the feedback RPM in, you could: 1. Send out either 87.5% or 100% drive signal and read your Max Feedback RPM. Since Max Feedback is the most critical scaling value to be determined, and since it is the first scaling value to be determined, this would be a very handy feature to the installer. 2. Determine the linearity of the drive and see how smoothly the motor runs over the intended operating range. As luck would have it, the Strider does have this capability. The screen is located in the test mode. Before going into the test mode, there are three choices to make in the program mode. Two of these choices are the first and last screens of the program menu PROGRAM FDBK IN - see page 15. After you have entered the FDBK IN PPR and MAX FDBK = DS, go to PROGRAM DISPLAY and change SETUP HIDE to SETUP SHOW. Next, exit the program mode and go the Adjust Menu screen ADJUST SETUP. Navigation through the view and adjust menus is shown on page 29. ADJUST SETUP ACCEL 10.0S DECEL 10.0S 1. Direct drive signal control - test mode. Test the linearity of the system and its low speed limits. Experimentally determine your Maximum Feedback value. 1st KEY STEP 0 RPT KEY STEP
