2Upon closing the brake, the drive generates a A7A1
Mechanical brake closing failed warning if the status
of the acknowledgement does not match the status
presumed by the brake control logic.
Upon opening the brake, the drive trips on a 71A3 Mech
brake opening failed fault if the status of the
acknowledgement does not match the status presumed
by the brake control logic.
The drive trips on a 71A5 Mech brk opening not allowed
fault if the brake open conditions cannot be fulfilled
(for example, the required motor starting torque is not
achieved).
Open fault
0.00 s / real32Defines a close fault delay, ie. time between brake
closure and brake close fault trip.
