Description
Determines how the drive reacts upon a mechanical brake
control error.
Note: If parameter 44.07 Brake acknowledge selection
to No acknowledge, acknowledgment status supervision is
disabled altogether and will generate no warnings or faults.
However, the brake open conditions are always supervised.
The drive trips on a 71A2 Mechanical brake closing failed
71A3 Mechanical brake opening failed
the acknowledgment does not match the status presumed
by the brake control logic.
The drive trips on a 71A5 Mechanical brake opening not
allowed fault if the brake open conditions cannot be fulfilled
(for example, the required motor starting torque is not
achieved).
The drive generates a A7A1 Mechanical brake closing failed
/ A7A2 Mechanical brake opening failed
of the acknowledgment does not match the status presumed
by the brake control logic.
The drive generates a A7A5 Mechanical brake opening not
allowed warning if the brake open conditions cannot be
fulfilled (for example, the required motor starting torque is
not achieved).
Upon closing the brake, the drive generates a
Mechanical brake closing failed
acknowledgment does not match the status presumed by
the brake control logic.
Upon opening the brake, the drive trips on a
Mechanical brake opening failed
acknowledgment does not match the status presumed by
the brake control logic.
The drive trips on a 71A5 Mechanical brake opening not
allowed fault if the brake open conditions cannot be fulfilled
(for example, the required motor starting torque is not
achieved).
Defines a close fault delay, i.e. time between brake closure
and brake close fault trip.
