14.5 Frequency Switch-off Limit
The max. permissible output frequency of the frequency inverter can be set to a low frequency value
via parameter Frequency Switch-off Limit 417. If this frequency limit is exceeded by the Stator
Frequency 210 or the Actual Frequency 241, the frequency inverter is switched off and error signal
"F1100" is displayed.

Via parameter max.Temp. Windings 617* you can set the temperature value above which a
warning message is output or an error switch-off of the frequency inverter is effected. The operating
behavior of the frequency inverter when the value set for max.Temp. Windings 617 is exceeded, can
be selected via parameter Motor Temp. Operation Mode 570.
