Hope some one can help. Got a fanuc OT that keeps giveing me 401 servo alarm and 414 servo alarm. Machine is in fresh air and no contct is made with anything when these alarms occur? Can anyone shed any light on what could be causing this? the 401 does have (VRDY) after it. Is this something connecting with the door interlock?

HELP..........................

What kind of machine is it? That may be a good place to start.

Check the connection of the pulsecoder at the x axis motor and on the x axis servo drive

first check Diagnose #720 when alarm occurs.
that will explain us what exactly happen
DGN (720) :
#7 (OVL) : Overload alarm
#6 (LV) : Insufficient voltage alarm
#5 (OVC) : Overcurrent alarm
#4 (HCA) : Abnormal current alarm
#3 (HVA) : Excessive voltage alarm
#2 (DCA) : Discharge alarm
#1 (FBA) : Disconnection alarm
#0 (OFA) : Overflow alarm
