PARAMETER DESCRIPTIONS
When you enable ID607 or ID608, the controllers start to monitor the changes in the supply
voltage. The controllers change the output frequency if it becomes too high or too low.
To stop the operation of the undervoltage and the overvoltage controllers, disable these 2
parameters. This is useful if the supply voltage changes more than -15% to +10%, and if the
application does not tolerate the operation of the controllers.

0 Controller switched off
Controller switched on (no

ramping)
Controller switched on (with
2
ramping)
When a value other than 0 is selected also the Closed Loop overvoltage controller becomes
active (in Multi-Purpose Control application).
608 UNDERVOLTAGE CONTROLLER 234567 (2.6.11)
Use this parameter to set the undervoltage controller out of operation.
See parameter ID607.
NOTE!
Over-/undervoltage trips may occur when controllers are switched out of operation.

609 TORQUE LIMIT 6 (2.10.1)
Use this parameter to set the torque limit control.
With this parameter you can set the torque limit control between 0.0 – 300.0 %.
