Parameterizing Extended Brake Control - Siemens SINAMICS S120 Commissioning Manual

4.11.3.2

Parameterizing extended brake control

When braking with feedback (p1275.5 = 1), the braking control responds to the feedback
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.
• Do not set the parameter assignment p1215 = 0 when there is a holding brake.
• Set all the relevant parameters correctly.
To select the type of brake control, proceed as follows:
1. 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)
