Controlling the safety functions
7.3 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 (drive 1 and
2) and group 2 (drive 3 and 4).
For this purpose, the same grouping for "Safe Torque Off" must be performed on both the
Control Unit and the Motor Modules.
Figure 7-5 Example: Grouping terminals with Motor Modules booksize and CU320-2 DP
Information on the parallel connection of chassis type Motor Modules
When chassis format 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.
