Data Description
8.2 Parameters for SINAMICS S120
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 is 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
p9621 BI: SI Safe Brake Adapter signal source (Control Unit)
Setting of the signal source for the Safe Brake Adapter (SBA).
This therefore defines via which digital input the Safe Brake Adapter checkback
signal (SBA_DIAG) is read in.
p9621/p9821 = 0:
no Safe Brake Control (SBC) available with Safe Brake Adapter (SBA).
p9621/p9821 = r0722.x (x = 0, 1 ... 7)
Safe Brake Adapter and booksize unit (no Communication Interface Module
(CIM)).
p9621/p9821 = r9872.3
Safe Brake Adapter and chassis unit(CIM).
See also: p9601, p9602, p9821
For a crosswise data comparison between p9621 and p9821, no difference is
tolerated.
The following must apply when using the "Safe Brake Adapter" function:
p9601 = p9801 <> 0 and p9602 = p9802 = 1
Unit: Default value:
- - 0
