About the 0-56921-403

The 0-56921-403 device is classified as a part of the Reliance Electric Limited GV3000 line of AC Motor Control Drives and parts; this model is a replacement regulator board for the GV3000 drives. The board is used in drives designed with vector-based functionalities and can regulate the motor’s speed, torque, and directional control utilizing a pulse-width modulated signal.

The Regulator Board component is a required add-on module. The 0-56921-403 regulator board is outfitted with a microprocessor and can regulate the drive’s system because of it. The 0-56921-403 is designed to accept feedback signals from the power circuit, an external speed reference signal, and encoder data (when set up for Flux Vector Control regulation).

The 0-56921-403 can provide such functionalities as sending the PWM gate signals to the IGBT modules corresponding to the speed or frequency reference. It can display the data in a four-character display screen and regulate the 14 indicator LEDs. The 0-56921-403 is outfitted with an analog output and provides a snubber resistor brake signal.

The 0-56921-403 model is considered a replacement model for regulator boards that have gone out in the GV3000 drives; an extensive and lengthy procedure on how to remove and install the board without suffering personal injury can be found in section one of the D2-3333 manual. Please make sure that at all times, the installation or removal instructions are followed to ensure that it keeps the user from getting injured or potentially damaging the enclosure of the chosen GV3000 drive.
