Commissioning Manual, 06/2020, 6SL3097-5AA10-0BP2
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".
There are no further setting options for this option. The state of the holding brake is
displayed in the dialog.
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.
