Bit #6 (OFS) indicates an A/D converter error within the amplifier. 3. Step-by-Step Troubleshooting Procedure
If the alarm persists, the itself is likely defective and needs internal repair or replacement.
The alarm is triggered when the CNC control and servo amplifier detect a problem that prevents the axis from operating correctly. This could be anything from incorrect voltage reaching the amplifier to a physical problem with the motor itself. fanuc 414 servo alarm z axis detect error repack
: Coolant or oil ingress in the motor connectors or power leads.
(if possible):
The Z-axis amplifier (SVM) is showing [e.g., 8, 9, or A] on the 7-segment display. Diagnostic Screen: DGN 200: [e.g., 00010000] DGN 204: [e.g., 01000000] Steps Taken So Far:
: Bit #6 (OFS) indicates an A/D converter issue. Bit #6 (OFS) indicates an A/D converter error
Navigate directly to your electrical cabinet to inspect the drive units. The physical LED on the servo amplifier module will reveal the exact cause.
: General power supply or axis control card failure. 2. Check the Diagnostic Screen Diagnose a Fanuc High Current Alarm in 10-Steps The alarm is triggered when the CNC control
The most common cause. Coolant can seep into the motor connectors or cables, creating a bridge that spikes the current. Mechanical Resistance:
