REGEN CONTROL
Designed for 4Q Regen Control
Mode.
This function block is used to
setup, sequence and monitor the
operation of the drive when used in
4Q Regen Control Mode.

Parameter Descriptions
PRECHARGE CLOSED
Range: FALSE / TRUE
This parameter is used to indicate the external precharge contactor is closed, i.e. the external
precharge resistor is no longer in circuit.
DC VOLTS DEMAND
Range: 0 to 1000V
Use this to set the demanded dc link volts for the common dc bus. It must be set higher than the
peak of the mains supply, but lower than the overvolts (820V on 400V products, 410V on 230V
products).
BRAKE MODE
Range: FALSE / TRUE
Setting this paramenter True allows the drive to generate energy into the mains in common dc link
systems. The regeneration occurs when the dc link is higher than the DC VOLTS DEMAND
level. In this mode the drive will not draw energy from the mains. The drive acts purely as a
braking unit.
SYNCHRONIZING
Range: FALSE / TRUE
This diagnostic reads True during the mains synchronisation period. This occurs when the drive is
first run in 4Q Regen Control Mode. This synchronising period lasts for 100ms.
SYNCHRONIZED
Range: FALSE / TRUE
This diagnostic reads True when mains synchronisation has been successfully completed.
PHASE LOSS
Range: FALSE / TRUE
This diagnostic reads True if the drive suspects there is a missing input phase from the mains
supply.
CLOSE PRECHARGE
Range: FALSE / TRUE
This diagnostic controls the operation of the external precharge contactor required by the 4Q
Regen Control Mode.
ENABLE DRIVE
Range: Enumerated - see below
This diagnostic is used to enable drives on a common dc link system supplied by a drive using the
4Q Regen Control Mode. The diagnostic reads True if mains synchronisation has been successful
and the drive is Healthy.
