Some "pulse mismatch" errors can be cleared by navigating to the system menu and performing a pulse coder reset .
A malfunctioning pulse coder (encoder) inside the servo motor or a failure in the servo amplifier’s feedback circuit. Electrical Interference: fanuc 366 alarm
in the built-in pulse coder of a specific axis. This fault occurs when the servo system detects that the feedback signal from the motor's internal encoder has lost data integrity or skipped a pulse. DNC Electronics Ltd Alarm Meaning & Causes Some "pulse mismatch" errors can be cleared by
The Fanuc 366 alarm is a robust protection feature. If you encounter it, start with the pneumatics (check the gauge) before swapping parts. It is usually an external mechanical issue rather than a failure of the Fanuc control board itself. This fault occurs when the servo system detects
If you do not have a backup, do not clear the PMC. The machine will become a brick.
