Use a Megohmmeter to check the insulation resistance of the Z-axis motor windings. If it reads near zero, the motor has a short to ground and must be rewound or replaced. 3. Contaminated Power Cables Coolant and oil are the enemies of CNC electronics.
One of the most common "stories" in the shop is coolant leaking into the motor's power or feedback connectors. This creates a short circuit that triggers the 414 alarm instantly. fanuc 414 servo alarm z axis detect error
can force the motor to strain excessively to hold the axis up. Feedback Issues: pulse coder (encoder) or a disconnected/damaged feedback cable. Drive/Amplifier Failure: A malfunction within the Intelligent Power Module (IPM) or the amplifier’s internal circuitry. Troubleshooting Steps HELP!! Servo Alarm No. 414: X-axis detect error Use a Megohmmeter to check the insulation resistance
Whether the alarm happens or during axis movement Contaminated Power Cables Coolant and oil are the
