Safety Integrated Basic Functions
10.8 Control via terminals on the Control Unit and Motor/Power Module
Drive functions
698 Function Manual, 11/2017, 6SL3097-4AB00-0BP5
Both terminals must be energized within the tolerance time p9650, otherwise a fault will be
output.

Grouping drives (not for CU310-2)
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
Connect the p9620 parameters of all drives that belong to a group with a single DI
(r0722.x) of the CU320-2.
2. Switch-off signal path (Motor Module / Power Module with CUA3x)
Wire the terminals for the individual Motor Modules / Power Modules, belonging to the
group, with CUA31/CUA32.
Note
Parameterization of the grouping
The grouping must be configured (DI o
n Control Unit) and wired (EP terminals) identically in
both monitoring channels.
Note
Response of STO for grouping
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 al
so switch to "Safe Torque Off" (STO).
