Controlling the safety functions
5.3 Control of "STO" and "SS1" via terminals on the Control Unit and the 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.
Figure 5-7 Example: Grouping terminals with Motor Modules Booksize and CU320-2
Notes on connecting Motor Modules format Chassis or Chassis-2 in parallel
When Motor Modules in the Chassis or Chassis-2 format are connected in parallel, a safety-
relevant 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.
