1 1-V/ Ctrol unti Group 1- V/ urve seleti ~ When V / mode without PG or V / mode with PG is applied, V / harateristi of inverter output an be set at 1-.. When using V / f urve, the inverter input voltage must be set by 1-. There are three ways to set V / f urve: (1) 1- = to E: hoose the 1 default types ( to E). () 1- =, use 1-~1- and 1-1~1-1, for users to define V/f urve with voltage limitati. () 1- = : use 1-~1- and 1-1~1-1, for users to define V/f urve without voltage limitati.. The default of 1- is, and when 1- is set to 1 1-~1- and 1-1~1-1 have the same tents.. When you selet e of the 1 default types, the set values from 1- to 1-1 will be automatially hanged. There are three types of set values for 1-1 ~ 1~ 1- and 1- ~1- Their values are determined by the inverter apaity.. Refer to the V / harateristis in ~ 4... This parameter is not affeted by the initializati parameter (1-). Type Speifiati 1- Table HP V/f urve V/ urve *1 Type Speifiati 1- V/ urve *1 General appliati Hz Hz Hz Hz 1 ( original value).

If 1- is set to any other value but not or, the parameter an not be hanged. Please follow the rules of the frequeny, or the warning message "SE" of V / f urve tuning error will be displayed. max > base > mid mid1 > min (1-) (1-1) (1-4) (1-) (1-) If 1-4 and 1- (or 1-1 and 1-) are set to the program will ignore the set values of min and Vmin. There are not relevant rules for voltage (from 1- to 1-). If the trol mode is hanged through - parameters 1-( min ) and 1- (V min ) will hange the default s of various trol mode. Refer to the following V / urve defined by users. 4-

6 igure 4..1 V/ urve defined by users Set the V / urve based the allowed load harateristi of the motor. In the appliati of low and high speed, the motor may overheat. If the motor operates under this diti for lg time, you have to pay speial attenti to the motor ooling. If the automati boosting funti is started by parameter 1-1, starting and operating under the diti of low frequeny, the motor voltage will automatially hange to provide adequate motor. 4-1
