Terminals for STO, SS1 (time-controlled), SBC

The functions are separately selected/deselected for each drive using two terminals.

1. Switch-off signal path (CU310/CU320)

The desired input terminal is selected via BICO interconnection (BI: p9620[0]).

2. Switch-off signal path (Motor Module/Power Module/CUA31)

The input terminal is the "EP" ("Enable Pulses") terminal.

Both terminals must be operated simultaneously, otherwise a fault will be issued.

Grouping drives (not for CU310)

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 (CU320)

By connecting the binector input to the joint input terminal on the drives in one group.

2. Switch-off signal path (Motor Module/CUA31)

By appropriately connecting-up the terminals for the individual Motor Modules/Power Modules belonging to the group with CUA31.

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)".
