NBRC-51C | ABB CHOPPER CONTROL BOARD

Control board Circuit board in which the control program runsBrake chopper Conducts the surplus energy from the intermediate circuit of the drive to the brake resistors when necessary. The chopper operateswhen the DC link voltage exceeds a certain maximum limit. The voltage rise is typically caused by deceleration (braking) of a high inertia motor.This chapter contains the dimension drawings of the brake chopper module, as well as the standard brake resistors and cooling fans.The dimensions are in millimeters. To convert to inches, use the formula: 25.4 mm = 1 in.
