Explanation
Circuit board in which the control program runs
Conducts the surplus energy from the intermediate circuit of the
drive to the brake resistors when necessary. The chopper operates
when the DC link voltage exceeds a certain maximum limit. The
voltage rise is typically caused by deceleration (braking) of a high
inertia motor.
Brake chopper enclosed inside a metal frame or enclosure.
Intended for cabinet installation. See
Brake chopper modules under control of one control board and
related accessories. The control board is considered part of the unit.
Dissipates the drive surplus braking energy conducted by the brake
chopper to heat. Essential part of the brake circuit. See
