The problem is parameter write is not getting enabled. Unit is not going in System mode.
At present APC alarms are displaying in message.
For this we were trying to set reference. We found parameter write is not enabling in SETTING (HANDY). There is no response if we press SYSTEM hard key.
Model of CNC : FANUC Series 0i-TD.
Machine Builder Name : Colchester Harrison 600 Group
