Data Description
8.2 Parameters for SINAMICS S120
p9602 SI enable safe brake control (Control Unit)
Sets the enable signal for the function safe brake control (SBC) on the Control
Unit.
0: SBC not enabled
1: Close the holding brake when SH is selected or when SI errors occur
The safe brake control function only becomes active if at least one safety moni-
toring function is enabled (i.e. p9501 not equal to 0 and/or p9601/p9801 not
equal to 0).
If a motor holding brake is not being used then it does not make any sense to
enable the parameterization "no motor holding brake available" and "safe brake
control" (p1215 = 0, p9602 = p9802 = 1).
The parameterization "motor holding brake the same as sequence control,
connection via BICO" and "safe brake control" enabled (p1215 = 3, p9602 = 1,
p9802 = 1) does not make sense.
The parameterization "motor holding brake without feedback signals" and "safe
brake control" enabled (p1278 = 1, p9602 = 1, p9802 = 1) is not permissible.
Unit: Default value:
– 0
If p9602 = 1, the holding braking is closed when SH is selected or SI errors occur.
P9602 has priority over p1215 ("holding brake setting").

p9620 BI: SI signal source for STO (SH)/SBC/SS1 (Control Unit)
Sets the signal source for the following functions on the Control Unit:
STO: Safe Torque Off/SH: Safe standstill
SBC: Safe Brake Control
SS1: Safe Stop 1 (SS1, time monitored)
Depends on: See also: p9601
Note: The following signal sources are permitted:
– fixed zero (standard setting).
– digital inputs (DI 0 to DI 7 on the Control Unit NCU7xx.
– digital inputs DI 0 to DI 3 on the Controller Extensions (CX32, NX10, NX15).
– digital inputs (DI 0 to DI 3 on the Control Unit 310 (CU310).
It is not permitted to interconnect to a digital input is in simulation mode.
Unit: Default value:
– 0
