Controlled shut down (K-EN = 0):
If the actual speed reaches < 1% of min(N-NMAX, V-NMAX) or the ramp time exceeds 1
second, the brake is activated and the pre-set speed (I-NCMD) is immediately set to 0 (to
support the braking effect). After 1 second + M-BRDI, the brakes engage and the control-
ler/output stage is disabled.
Shut-down after opening the safety circuit:
If the actual speed reaches < 1% of min(N-NMAX, V-NMAX) or the ramp time exceeds 500
ms, the brake is activated and the pre-set speed (I-NCMD) is immediately set to 0 (to sup-
port the braking effect). After 500 ms + M-BRDI, the brakes engage and the control-
ler/output stage is disabled.
