HI FRIENDS,
we have a charmilles 230 robofil wire cut EDM machine. works with FANUC 18 i and FANUC DRIVES. Following alarms displays in the screen and not getting reset.
401 X AXIS VRDY OFF
401 Y AXIS VRDY OFF
401 U AXIS VRDY OFF
401 V AXIS VRDY OFF
401 Z AXIS VRDY OFF

we checked the PSM CX4 emergency loop connector continuity . its closed. the 24v signal is present. but still the main contactor (MCC)is not energizing through CX3 . when CX3 is bypassed with a wire the contactor gets on. ( the contactor and the MCC loop is ok). but still alarms are present.
what can be the issue?

IN THIS CONTROLLER DAIGNOSIS 358 IS ALSO NOT SHOWING !!

Did you figure out what was causing this alarm? We just got a Charmilles 330F that has the same issue.
