Fanuc 0 - Please turn off power

PLEASE TURN OFF POWER

A parameter that requires power-off to take effect has been modified while parameter write was enabled (PWE=1). The Fanuc control requires a complete power cycle before the new parameter value becomes active.

Root Cause Summary

Alarm 000 is a notification, not a fault condition. It occurs when a parameter requiring power cycle to activate has been changed while parameter write enable (PWE) was set to 1. The control is prompting for a complete power cycle to implement the modified parameter value.

Safety

  • Verify corrected program or parameters before resuming machining

Causes and Fixes

  1. 1

    Record which parameter was changed and the new value for verification after reboot.

  2. 2

    Set parameter write enable back to 0 (PWE=0) using the keep relay or parameter setting page.

  3. 3

    Perform a complete power cycle - turn the control OFF, wait 10 seconds, then turn back ON.

    Ensure machine is in a safe state and all axes are secure before power cycling.

  4. 4

    After reboot, verify the parameter change took effect by checking the parameter value and testing affected functionality.
