SIMODRIVE 611 Infeed module Problem

Control card could be faulty (either relay contact or coil problem or relay coil supply problem)

Try by swapping control card.

 See the infeed module basic drawing . T. 72 is a NO contact of small relay. --if you checked all enabling and you all drives are no problem (drive status  transfer back to infeed from device bus) --your yellow LED on ,your green LED off?---

if everything ok as you said it is possible that small relay has issue. I suggest --NOT replace control card for Infeed (it is not like drive--card and power section removable ) --you need replace the whole infeed module to trouble shooting --then send bad module to  repair shop 

the infeed module version A,B or C will compatible  if power rating same

Thank You.
