How is CN3, the regeneration unit connector, to be used?

Filed under: Stepper Motors — mota @ 3:01 am

In occasional cases where the AS motor is driving very large inertial loads, a regeneration unit supplied by OM can be used. P/N: RGA50-A (100V), and RGA50-C (200V). CN3 on the driver is actually connected direclty to the rectified DC power from the driver, and is around 164VDC. The regeneration unit from OM connects to CN3 and, by using a current controlling circuit, absorbs any surges in current caused by back emf. Therefore, customers should not design their own regeneration unit for this purpose.
