Optional Braking Chopper
The optional braking chopper uses resistor braking to provide motor braking and shorter
deceleration times, eg, for:
- Reduction of coasting down time, eg, for conveyor belts, fans, and pumps
- Emergency stops
The braking chopper cabinet connects to the right side of the drive as well as to the braking
resistors, which are external to the ACS1000 and not part of the product scope.

The braking chopper is controlled and monitored by the ACS1000.
