42.12 Brake fault func Defines how the drive reacts in case of mechanical brake
control error. If brake control supervision has not been
activated by parameter 42.01 Brake ctrl, this parameter is
disabled.
Fault The drive trips on fault BRAKE NOT CLOSED / BRAKE NOT
OPEN if the status of the optional external brake
acknowledgement signal does not meet the status presumed
by the brake control function. The drive trips on fault BRAKE
START TORQUE if the required motor starting torque at
brake release is not achieved.
0
Alarm The drive generates alarm BRAKE NOT CLOSED / BRAKE
NOT OPEN if the status of the optional external brake
acknowledgement signal does not meet the status presumed
by the brake control function. The drive generates alarm
BRAKE START TORQUE if the required motor starting torque
at brake release is not achieved.
1
Open flt The drive generates alarm BRAKE NOT CLOSED (when
closing the brake) and trips on fault BRAKE NOT OPEN
(when opening the brake) if the status of the optional external
brake acknowledgement signal does not match the status
presumed by the brake control logic. The drive trips on
BRAKE START TORQUE if the required motor start torque at
brake release is not achieved.

42.13 Close flt delay Defines a close fault delay, i.e. the time between when the
brake is closed and when a brake close fault is generated.
0.00 … 600.00 s Brake close fault delay. 100 = 1 s
