1 2. Using LCD Digital Operator Functions of LCD digital operator JNEP-31(V) LCD digital operator has 2 modes: mode and mode. When the inverter is stopped, mode or mode can be selected by pressing the. In mode, the operation is enabled. Instead, in the mode, the parameter settings for operation can be changed but the operation is not enabled. The component names and function are shown as below: REMOTE SEQ REF DIGITAL OPERATOR JNEP-31(V) JOG operation mode indicators : lit when in mode : lit when there is a forward run command input : lit when there is a reverse run command input SEQ : lit when the run command is enabled from the control circuit terminal or RS-485 port (REMOTE mode) REF : lit when the frequency reference from the control circuit terminals (VIN or AIN) or RS-485 port is enabled (REMOTE mode) LCD Chinese : 2-line by 8-character English : 2-line by 20-character Keys (Key functions are defined in Table 7) Fig. 8 LCD Digital operator Remote/Local switch function: Local mode command input from LCD Digital Operator (SEQ off) Frequency command input from LCD Digital Operator (REF off) Remote mode command input from control circuit (when Sn-04=1) or RS-485 comm. port (when Sn-04=2) (SEQ lit) Frequency command input from control circuit (when Sn-05=1) or RS-485 comm. port (when Sn-05=2) (REF lit) 2-1

JOG JOG / INCREMENT DECREMENT / Enable jog operation from LCD digital operator in operation (). Select the rotation direction from LCD digital operator. Set the number of digital for user constant settings. Also It acts as the reset when a fault has occurred. Select the menu items, groups, functions, and user constant name, and increment set values. Select the menu items, groups, functions, and user constant name, and decrement set values. Select the menu items, groups, functions, and user constants name, and set values (). After finishing the above action, press the (). Start inverter operation in () mode when the digital operator is used. The will light. Stop inverter operation from LCD digital operator. The can be enabled or disabled by setting the parameter Sn-07 when operating from the control circuit terminal., indicator lights or blinks to indicate the 3 operating status: Inverter output frequency Frequency setting Blink OFF 2-2

Press the, the system will switch into mode. If the fault occurs, press the and enter into mode to monitor the corresponding Un- contents. If a fault occurs in the mode, the corresponding fault will be. Press the and reset the fault. *2 The monitored items will be according to the settings of Bn-12 and Bn-13. *3 When in the mode, press the and, the setting values of Sn- and Cn- will only be for monitoring but not for changing or setting. 2-3

4 Parameter description The inverter has 4 groups of user parameters: Parameters Description An- Frequency command Bn- Sn- Cn- Parameter groups can be changed during running System parameter groups (can be changes only after stop) Control parameter groups (can be changed only after stop) The parameter setting of Sn-03 (operation status) will determine if the setting value of different parameter groups are allowed to be changed or only to be monitored, as shown below: Sn-03 mode mode To be set To be monitored To be set To be monitored 0 *1 An,Bn Sn,Cn An,Bn,Sn,Cn - 1 An Bn,(Sn,Cn) *2 An Bn,Sn,Cn *1: Factory setting *2: When in mode, the parameter group Sn-, Cn- can only be monitored if the and the are to be pressed simultaneously. *3:After a few trial and adjustment, the setting value Sn-03 is set to be 1 so as not be modified again. 2-4

5 Example of using LCD digital operator Note: Before operation: Control parameter Cn-01 value must be set as the input AC voltage value. For example, Cn-01=380 if AC input voltage is 380. This example will explain the operating of the inverter according to the following time chart.
