Activates/deactivates (and selects the source for) brake
open/close status (acknowledgement) supervision.
When a brake control error (unexpected state of the
acknowledgement signal) is detected, the drive reacts as
defined by parameter 44.17 Brake fault function.

0.00 s / real32Defines the brake open delay, ie. the delay between the
internal open brake command and the release of motor
speed control. The delay timer starts when the drive has
magnetized the motor and increased the motor torque to
the level required for brake release (parameter 44.3 Brake
open torque reference). Simultaneously with the timer start,
the brake control logic energizes the brake control output
and the brake starts to open.
Set this parameter to the value of mechanical opening
delay specified by the brake manufacturer.
