4Q operation for motors with mechanical brake

• The brake coil can be used as a braking resistor in 4-Q operation.
• Brake voltage is generated internally within the unit, which means it is grid-independent.
• Should the regenerative current-carrying capacity not be sufficient for the application, refer to the chapter 4Q operation with integrated brake and external brake resistor:
• The following figure shows the current-carrying capacity of the DR.. motor brake coils:
