607
Overvoltage
controller
(2.6.9)
These parameters allow the under-/overvoltage controllers to be switched out of operation.
This may be useful, for example, if the mains supply voltage varies more than –15% to +10%
and the application will not tolerate this over-/undervoltage. In this case, the regulator controls
the output frequency taking the supply fluctuations into account.
0 Controller switched off
1 Controller switched on = Minor adjustments of OP frequency are made
608
Undervoltage
controller
(2.6.10)
See par. ID607.
Note: Over-/undervoltage trips may occur when controllers are switched out of operation.
0 Controller switched off
1 Controller switched on = Minor adjustments of OP frequency are made
