Fanuc alarm PS000: PLEASE TURN OFF POWER
system alarm · Fanuc 0i-D
What it means
The classic power-up-class P/S alarm: a parameter whose new value only takes effect after a reboot has been changed, and the CNC holds this alarm until the control is switched off and on again. It is informational rather than a fault - the machine stays alarmed purely to force the power cycle.
Likely causes
- Servo/spindle/system parameter edited that requires restart
- Parameter restored from backup containing such changes
- PMC or option setting changed via G10/parameter screen
Triage note: Not a hardware fault: complete your parameter edits, then power the control off/on. If it reappears without edits, check for a PMC sequence writing parameters at startup.
