If the configuration is set to "No motor holding brake available" during ramp-up, then
an automatic identification of the motor holding brake is performed. If a motor holding
brake is detected, the configuration is set to "Motor holding brake like sequence
control".
If a motor holding brake is used via the drive-integrated brake connection of the Motor
Module, this option must not be set. If an external motor holding brake is used,
p1215 = 3 should be set and r0899.12 connected as control signal. With activated
"Extended brake control" (r0108.14 = 1) function module, r1229.1 should be
connected as control signal.
