- - - - t t t t d d d d C C C C DC injection standstill braking time
If the time is increased to 25.5 s, "Cont" is displayed. The DC injection is then
continuous at standstill.
- - - - J J J J P P P P F F F F Skip frequency prevents prolonged operation at a frequency range of 2 Hz
around JPF. This function prevents a critical speed which leads to resonance.
Setting the function to 0 renders it inactive.

Following operation at LSP for a defined period, a motor stop is requested
automatically. The motor restarts if the frequency reference is greater than LSP
and if a run command is still present.
Caution : value 0 corresponds to an unlimited period.
(1) In is the nominal speed controller current shown in the catalog and on the speed controller rating
plate.
The parameters in shaded boxes appear if the corresponding functions have been configured
in the drC- or I-O- menus.
