Hello,
can these alarms be found in ladder logic?
I know I can find alarms like 1003, 1016 etc, but these spindle and servo amp related alarms, can they be found in ladder logic somewhere?
Or do they only occur in servo drives?

If they can be found, how, because I cannot manage to find them.

Thanks

sounds like a dead power supply to me with those faults basically saying it cant communicate with the spindle or servo drives. probably lost the 24V

Those alarms are not explicit in the ladder. When a servo alarm occurs on the Fanuc side the signal for servo off is sent to the ladder in case the machine builder wants to use it in the ladder. A good example might be a brake on a gravity axis being activated at servo off.
