Opening the motor holding brake via P1218
Using parameter P1218, you can force the brake to open, e.g. in order to be able to
manually move a conveyor drive.
Secure loads held by the brake!
Since this procedure cancels the "Brake active" signal which, in turn, causes the brake to
be forced open, the user must ensure that, even when the motor has been powered-down,
all loads held by the brake are secured before the signal is canceled.
