MCK basic functions
bMBrakeReleaseOut
BOOL
Holding brake control: Trigger signal for the holding brake control switching
element via a digital output
•Use bit0 in C02582
to activate inverted switching element triggering.
FALSE Apply brake.
TRUE Release brake.
bMBrakeReleased
BOOL
Holding brake control: "Brake released" considering the brake release time
• When the holding brake is triggered to close, bMBrakeReleased is immediately set
to FALSE even if the brake closing time has not yet elapsed!
TRUE Brake released (after the brake release time has expired).
