    Default Get this alarm when spindle is running. Need help with PLC ladder, see picture.

    I get this alarm after a few seconds after the spindle get a run command. The spindle is running just fine at the set speed. But it seems like the control doesnt get the end OK signal and give an alarm.

    I found the alarm in the PLC & parameter list for the machine, but i dont quite understand what the line says. Could anyone explain whats going on here? And what the problem could be.


    Thanks!

    Coil G120.4 needs to turn on before this timer times out. Check to see why this coming in not turning on.

    I have also found the zero speed relay and/or the up-to-speed relay, which this looks like, on the spindle drive has failed, if it has the relay confirmation output.

    Hmm yes that is what i am thinking also. But where does a relay like that sit in the machine? Its a Denford Cyclone with Fanuc 0T-B from 1988.
