Simultaneity And Tolerance Time Of The Two Monitoring Channels - Siemens Sinamics S120 Function Manual

Safety Integrated basic functions
9.8 Control via terminals on the Control Unit and Motor/Power Module
Example: Terminal groups
It must be possible to select/deselect "Safe Torque Off" separately for group 1 (drives 1 and
2) and group 2 (drives 3 and 4).
For this purpose, the same grouping for "Safe Torque Off" must be realized both for the
Control Unit and the Motor Modules.

Information on the parallel connection of chassis type Motor Modules
When chassis type Motor Modules are connected in parallel, a safe AND element is created
on the parallel drive object. The number of indexes in p9620 corresponds to the number of
parallel chassis components in p0120.
