Grouping drives
If the function is to be simultaneously initiated for several drives, the terminals for the
corresponding drives must be grouped together:
● Control Unit
● Motor Module
Example: Terminal grouping for safe standstill (SH)
The "Safe standstill" function should be able to be selected/deselected separately for group
1 (drive 1 and 2) and group 2 (drive 3 and 4).
The same grouping for the safe standstill must be performed for both the Control Unit and for
the Motor Modules.
4-4
By appropriately interconnecting the binector input to a joint input terminal for the drives
to be combined to form a group.
By appropriately connecting terminal "EP" for the individual Motor Modules belonging to a
group.
Note
The same grouping must be set in both monitoring channels.
If a fault in a drive causes the safe standstill (SH), the other drives of the same group will
not automatically be placed in the safe standstill (SH).
