This parameter should be set to the level of flux required before the torque proving latch can be set.
When this parameter is set to 1, the torque present signal is only given when the armature current is above the threshold in the positive direction.
This parameter is provided for the case where users wish to have positive feedback that the brake is released. This could be done using a brake
release limit switch, or an auxiliary contact on the brake contactor. A digital input needs to be routed to this parameter to monitor the brake state and
Pr 12.55 needs to be set to enable this feature.
By default, the brake release action defined by Pr 12.49 is triggered by the brake release logic (Pr 12.40). When this parameter is set to 1, the brake
release action is triggered by an external feedback (Pr 12.54).
