4Q operation for motors with mechanical brake
• The brake coil can be used as a braking resistor in 4Q operation.
• Brake voltage is generated internally within the unit, which means it is grid-inde-
pendent.
• The following figures show the regenerative load capacities of the internal brake
coils. If the regenerative load capacity is not sufficient for the application, connect
an additional braking resistor, see the following chapter.
• The following figure shows the load capacity of the DR.. motor brake coils:
