: If the motor is in a wet environment, check for coolant or oil ingress in the encoder connector. Cleaning the connector often resolves intermittent 366 errors. Cable Continuity Test
: The motor parameter number set in the CNC is incompatible with the physical driver installed. Hardware Malfunction fanuc 366 alarm
Your CNC control sends a command to the servo motor to move. The motor spins, and a device called a Pulse Coder (or encoder) attached to the motor shaft measures exactly how far it turned. It sends this data back to the control via a feedback cable. : If the motor is in a wet
Excessive motor vibration can cause the encoder's optical read head to miss lines on the grating. Hardware Degradation: fanuc 366 alarm
