Subject: Troubleshooting and Repack Procedure for Fanuc Servo Alarm 414 (Z-Axis) Alarm Code: SV0414 (Series 16i/18i/21i/0i) or APC 414 (Series 0/10/11/12/15) Symptom: Digital servo system error; Z-axis movement prevented.
If Z axis is vertical (common in mills, machining centers): If this is for a maintenance app or
If this is for a maintenance app or knowledge base, implement the feature as:
The Fanuc digital servo system operates on a closed-loop principle. The CNC controller sends a command signal to the Servo Amplifier. The amplifier powers the Servo Motor. The motor spins, and the Encoder (Pulse Coder) attached to the rear of the motor sends positional data back to the amplifier and the CNC control. To troubleshoot effectively
