0-56921-502AA

Product Description

The 0-56921-502AA model is described by Reliance Electric as a regulator board. This model will mount with GV3000 drives, specifically ones in the range of 1-5 HP. This model is outfitted with modules and nodes that assist the drive when used with a vector-based regulator. Regulation of the 0-56921-502AA board is achieved through the processing of major and minor digital feedback loops in flux or sensorless vector control. This board can also process dynamic response outputs and help with the regulation and maintenance of the motor speed on the chosen drive. 

There are specific installation and removal procedures that must be followed to ensure that there is no personal injury, property damage, or potential loss of life. When removing or installing the 0-56921-502AA board, the user should ensure that all power is disconnected and that all voltages have evaporated; not following this simple procedure can result in loss of life, shock, property damage, and more. All voltages and DC bus potentials would be checked with a voltmeter to make sure everything has been discharged so the model can be removed and installed safely. 

If the 0-56921-502AA unit is being replaced with a drive that has an option board, the option board will need to be removed from the support bracket, then the regulator board ribbon connector will need to be removed from the option board, and the old regulator board will then need to be removed from the support bracket. Before putting the replacement regulator board in the drive, make sure that all of the jumper settings on the new regulator board are identical to the old regulator board. 

For more installation and removal procedures of the 0-56921-502AA model, refer to the D2-3343 manual from Reliance Electric.
