p1254
Vdc-max controller automatic detection of EIN
level
Factory setting: 0
Activates / deactivates automatic detection of the switch-on level for the Vdc-max controller.
Values: 0: Automatic detection disabled
1: Automatic detection enabled
Settings
Parameter p1240 functions as enable: 0: controller disabled, 1: controller enabled.
You use p1242 to define the starting point of the Vdc-max controller. This is the
maximum value of the DC link voltage that cannot be exceeded. If the DC link
voltage is below the starting point, the controller remains inactive. The controller
gain can be changed by means of p1250. The set ramp-down remains inactive
while the Vdc-max controller is active. The ramp-down time increases the more
excess kinetic energy is stored in the drive train.
