Fanuc alarm SV0466: MOTOR/AMP. COMBINATION
αi/βi Servo (SV0xxx) · Fanuc 0i-D
What it means
The amplifier's maximum current rating differs from what the motor requires per parameter No. 2165. The check guards against driving a motor from an undersized or mismatched amplifier. Verify the physical amplifier model matches the design, and that parameter No. 2165 holds the correct ampere value for the motor fitted.
Likely causes
- Wrong amplifier model installed for this axis
- Parameter No. 2165 incorrect after parameter reload
- Axis-to-amplifier assignment (connection command) wrong
