It is permissible to simultaneously enable the safety functions integrated in the drive (p9601/
p9801 < > 0) and the motion monitoring functions (p9501 < > 0). See also: p9801
p9602 SI enable Safe Brake Control (Control Unit)
Sets the enable signal for the function Safe Brake Control (SBC) on the Control
Unit.
0: Inhibit SBC
1: Enable SBC
See also: p9802
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 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, con‐
nection 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
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)
See also: p9601
Note:
The following signal sources are permitted:
● Fixed zero (default 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 in simulation mode.
When connecting n power sections in parallel, the following applies:
p9620[0] = signal source for power unit 1
... p9620[n-1] = signal source for power unit n
Unit: Default value:
- 0
