Product technial information：

Drive regulation is performed by a microprocessor on the Regulator board.  Drive operation is adjusted by the parameters entered 

through the keypad. The Regulator board accepts power circuit feedback signals and 

an external speed reference signal, as well as data from an encoder that is attached to 

the motor when set up for FVC regulation. The Regulator board provides:

• PWM gating signals to the IGBT power devices

Based on the output of the control loop, the regulator sends PWM gating signals 

through the Current Feedback board to isolated drivers on the Gate Driver board. 

These drivers switch the Insulated Gate Bi-polar Transistors (IGBTs), producing a 

PWM waveform that corresponds to the speed (FVC regulation) or frequency (V/Hz 

regulation) reference. The IGBTs can be switched at either a 2, 4, or 8 kHz carrier 

frequency. 

• Form A and B contacts for drive status indicators

The Form A and B contacts are under control of the user via programmable 

parameters. A Form A or B transition can indicate drive status. The contacts are 

rated for 5 amps resistive load at 250 VAC/ 30 VDC and are made available through 

the terminal strip.

• Display data for a four-character display and fourteen indicator LEDs

For a description of the keypad/display, refer to section 2.8.6. For operational 

instructions.
