<1> Motor holding brake configuration
0 = No brake or brake always applied (brake connected to the power unit)
1 = Brake control active (brake connected to the power unit)
2 = Brake always released (brake connected to the power unit)
3 = Brake control active (brake connection can be interconnected using BICO)
Note:
A motor brake cannot be connected to all power units. p1215 is set to 3 and the brake is controlled via a digital output (e.g. TM31).
<2> Priority assignment (high -> low): p1215, p0858, p0855, p0856/p1219, apply brake from standstill detection, p1218.
<3> These blocks/modules are evaluated with the same sampling rate as the brake control and therefore may only be used to individually adapt
the brake control.
<4> If the brake is permanently applied or released (p0855, p0858 or p1215), the drive does not wait until the brake is released or applied.
