REGEN CONTROL
SETUP::MOTOR CONTROL::REGEN CNTRL
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
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
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
Setting this parameter 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.
Id DEMAND
Use this parameter in AFE current control mode to set the per-unit (PU) current demand that is proportional to the drive active
power.
Iq DEMAND
Use this parameter in AFE current control mode to set the per-unit (PU) current demand that is proportional to the drive
reactive power.
MAX CURRENT
This parameter sets the current limit applied to the 4-Q Regen drive in AFE current control mode.
