9.11 4-Q operation with motors with a 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 mains-
independent.
• 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 section).
• The following figure shows the load capacity of the brake coils from DR motors:
• The following figure shows the load capacity of the brake coils from DT/DV motors:
