Grouping drives
To ensure that the function works for more than one drive at the same time, the terminals for
the corresponding drives must be grouped together as follows:
1. Switch-off signal path
By connecting the binector input to the joint input terminal on the drives in one group.
2. Switch-off signal path (Motor Module/Power Module)
By appropriately wiring the terminals for the individual Motor Modules/Power Modules
belonging to the group.
Note
The grouping must be identical in both monitoring channels.
If a fault in a drive results in a "Safe Torque Off" (STO), this does not automatically mean
that the other drives in the same group also switch to "Safe Torque Off" (STO).
The assignment is checked during the test for the switch-off signal paths, The operator
selects "Safe Torque Off" for each group. The check is drive-specific.
