Priority assignment (high -> low): p1215, p0858, p0855, p0856, sequence control.
If p1215 = 0, 2 -> t = 0 ms.
Only if "Safety Integrated" is active.
If an external motor holding brake is used, p1215 should be set to 3 and r0899.12 should be interconnected as control signal.
r0046.21 = 0, as long as r0046.0 = 1 (OFF1 enable missing or switching on inhibited).
r0046.21 = 1, if p0858 = 1 or p0856 = 0.
The signal generation is shown simplified.
The internal signal includes signals that lead to OFF1 or OFF3 (e. g. BICO or fault response).
If the brake is permanently applied or released (p0855, p0858 or p1215) the drive does not wait while the brake is released or applied.
