4Q operation for motors with mechanical brake

  • In 4Q operation, the brake coil can be used as a braking resistor.
  • The brake voltage is generated internally in the device and is thus network-independent.
  • Should the regenerative current-carrying capacity be insufficient for the application, refer to chapter 4Q operation with integrated brake and external braking resistor.
  • The following figure shows the current-carrying capacity of the CM3C.. motor brake coils:

[J]

Maximum permitted energy per braking operation

[c/h]

Braking operations per hour
