enabled disabled 0 [Std mot. protect.]
In case of overload defined by
[Motor thermal prot.] (tHr) parameter, the
drive trips in OL2 and the letter L is flashing.
enabled enabled 1 [Std & stall mot. prot]
In case of overload defined by
[Motor thermal prot.] (tHr) parameter, the
drive reduces automatically the speed and
follows a fallback speed (80 % of Motor rated
frequency uL) (1).
If the overload remains during the fallback
speed, the drive trips in OL2 and the letter L
is flashing.

disabled enabled 3 [Slf cool stall ov.load]
In case of overload defined by
[Motor thermal prot.] (tHr) parameter, the
drive reduces automatically the speed and
follows a fallback speed (80 % of Motor rated
frequency uL) (1).
The drive will not trip in OL2.

enabled enabled 5 [Forc cool stall prot]
In case of overload defined by
[Motor thermal prot.] (tHr) parameter, the
drive reduces automatically the speed and

If the overload remains during the fallback
speed, the drive trips in OL2
