Control Mode Selection - GE VAT200 Quick Start Manual

4.2 Control Mode Selection

VAT200 Series inverter has three control modes:
1. General Vector Control Mode
2. VT Vector Control Mode (Special for Blower, Pump).
3. V/F Control Mode 。
The user can choose these modes with the digital keypad according to the application characteristics.
The factory setting is general vector control mode. Before operation, please set the control mode and
the relative parameters of the motor in accordance with the following flow chart. (The Vector control
mode only suits for the inverter with same capacity comparing to the motor, or a grade bigger or
smaller one).
Set the following parameter:
V/F Pattern
Torque Boost
Motor no load current
Motor Rated Slip
Max output frequency
Max output voltage
Medium output Frequency
Medium output voltage
Min output frequency
Min output voltage
Suitable motor capacity 0-02 (OL1 reference index)
※ Note:
1. Use V/F Control Mode:
(1) Use one inverter to drive several motors simultaneously
(2) Motor's nameplate is unknown or motor 's specifications are too special, it will
cause Auto-tuning fault.
(3) Specification of inverter and motor differ more than 1 class.
2. One inverter drives several motors (Only V/F mode available), set the motor parameter complying
with the following rules:
(1). As for the current, sum the rated current of all motors.
(2). As for others, input correct VF Pattern parameter (10-4~10-9).
3. When the nameplate of the motor is unknown, the inverter will set the internal parameter
according to the standard GE motor.
4. When parameter 0-00 does set to 2, the keypad will display 'Err2' in performing Auto tuning.
5. When VF control, 0-01~0-05 max. & min. value by the GE standard motor specification limit(one
more & one less level). When VF control, no district.
