Parameterizing The Brake Control - Siemens SINAMICS S120 Commissioning Manual

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
as a consequence result in death or severe injury.
• If a holding brake is being used, do not set the parameter assignment p1215 = 0.
• Correctly set all of the parameters involved.
Note
It is only permissible to activate brake control monitoring for booksize power units and
blocksize power units with Safe Brake Relay (p1278 = 0).

Parameterizing the brake control

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 the "Drive functions > Brake control" menu in the project navigator.
2. Select one of the following entries from the drop-down list:
– Motor holding brake like sequence control (p1215 = 1)
– Motor holding brake always open (p1215 = 2)
– Motor holding brake like sequence control, connection via BICO (p1215 = 3)

WARNING
WARNING
If the configuration is set to "No motor holding brake available" during ramp-up, then
an automatic identification of the motor holding brake is performed. If a motor holding
brake is detected, the configuration is set to "Motor holding brake like sequence
control".
If a motor holding brake is used via the drive-integrated brake connection of the Motor
Module, this option must not be set. If an external motor holding brake is used,
p1215 = 3 should be set and r0899.12 connected as control signal. With activated
"Extended brake control" (r0108.14 = 1) function module, r1229.1 should be
connected as control signal.
