If the amplifier's STATUS LED is red or the ALM LED is illuminated at power-on without the spindle being commanded, the amplifier module itself is the likely failed component.\u003cstrong\u003eQ6: Can I replace just the spindle amplifier, or do I also need to replace the Power Supply Module (PSM)?\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIn most cases, only the spindle amplifier needs replacement. The PSM (A06B-6110 series) is a separate module that provides the shared DC bus; it typically survives spindle amplifier failures unless the amplifier failed catastrophically in a way that damaged the DC bus (e.g. a bus short-circuit). Before fitting the replacement amplifier, check the PSM's DC bus output voltage (should be approximately 283–300 V DC for the 200 V series) and inspect the PSM for any fault indicators. If the PSM is functional and within voltage spec, only the spindle amplifier module requires replacement.\u003cstrong\u003eQ7: Does replacing this spindle amplifier require re-parameterisation of the CNC?\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUsually not. The spindle amplifier A06B-6111-H006#H550 does not store machine-specific parameters internally in a way that requires re-entry after replacement — spindle parameters are stored in the CNC control unit's non-volatile memory (SRAM). After fitting the new amplifier, the CNC should recognise it on power-up and communicate normally. However, if the new amplifier has different firmware from the failed unit (possible if the replacement is a later production revision), a parameter check is advisable. Fanuc recommends verifying spindle parameters SP3000–SP3999 after any spindle amplifier replacement, particularly spindle motor model code (SP3000#0 and related parameters).\u003cstrong\u003eQ8: Is this amplifier compatible with 400 V AC (European standard) power supplies?\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eNo. The\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e#H550 suffix specifies the 200 V AC input series\u003c\/strong\u003e.
