8.5.4 "Open brake" function
You can also open the motor brake via digital signal sources (C0410/15) without using the
"Motor V1−V8" functions.
In order to prevent an overload of the brake by triggering it for too long, a maximum
triggering time can be parameterised via C0451. After this time has elapsed, the brake
automatically engages even if a trigger signal is available.
If the "Motor V1−V8" functions are active, the motor brake always is open automatically.
