Functional Description Special Functions
Examples of brake control
Deactivation of modulation
If the modulation is switched off (e.g. through control release or error), the brake
engages immediatle without a delay time.

Speed controlled operation
In case of missing rotation setting (status ‘LOW SPEED’) and a actual speed value
smaller than the speed hysteresis LE.37, the delay time of the brake expires. (Attention:
For the speed hysteresis a value of ≥ 15 min
-1
should be adjusted, since otherwise
the brake never engages at the smallest speed fluctuations). After expiration of the
delay time the brake application time starts, only after that the modulation is disabled.
