1.9.2 DC Link Voltage Control (VdcCtrl Reg - Max Regen Power)
The Function is available only with a Sensorless and Field Oriented regulation mode. The Block allows the
control:
· of the DC link voltage during regenerating (ex. deceleration), to avoid the Overvoltage alarm trip.
or
· the control of the power recovered on the DC link during regenerating.
The two functions are activated by setting the following parameters respectively in the Trq curr lim cfg / Tcrr lim
sel of the Torque Setpoint Block:
T lim Vdc ctrl for a control of the DC link voltage
T lim gen power for a control of the recovered power
During such phases the VdcCtrl P gain and VdcCtrl I gain parameters (gains) allow the tuning, if required, of
the DC link control.
