Parameterizing extended brake control

Overview
For braking with feedback (p1275.5 = 1), the brake control reacts to the feedback signal contacts
of the brake. If the period p1216 is longer than the time until the feedback signal comes, the
startup is delayed by the associated time difference.
In order to startup without delay when possible, the set period p1216 must be shorter than the
time until the feedback signal comes. If the period is set shorter, the alarm "A07931, brake does
not open" appears, however.
Selecting the type of brake control
Danger as a result of a damaged holding brake caused by incorrect parameter assignment
If the drive moves against the closed holding brake, this can destroy the holding brake and
cause death or serious injury.
• If a holding brake is being used, do not set the parameter assignment p1215 = 0.
• Set all the relevant parameters correctly.
To select the type of brake control, select one of the following entries from the drop-down list:
• Motor holding brake like sequence control (p1215 = 1)
• Motor holding brake like sequence control, connection via BICO (p1215 = 3)
