t monitoring of the infeed!
You must ensure sufficient power of the infeed module by setting this
parameter accordingly in the configuration.
The relay is activated if:
At NE module
– Heatsink–temperature monitoring trips
At 611D
– Motor–temperature monitoring trips
– Heatsink–temperature monitoring trips

Input current, enable circuits:
Terminals 48, 63, 64, and 65: Input current, optocoupler approx. 12 mA at +24 V
Terminal 663: Input current, optocoupler and start inhibit relay approx. 30 mA at
+24 V
When selecting the switching devices and the auxiliary contact on the main
switch, the contact reliability when switching low currents must be carefully
taken into consideration.
Switching capacity of the signaling contacts:
The max. switching power of the signaling contacts is specified in the interface
overviews of the modules in Chapters 5 and 6, and must be absolutely com-
plied with!
Note
All of the connected actuators, contactor coils, solenoid valves, holding brakes,
etc. must be provided with overvoltage limiting elements, diodes, varistors, etc.
This is also true for switchgear/inductances controlled by a PLC output.
