0233
Velocity Pulse Count Exceeded
Fanuc · Alpha i Series Servo Amplifier
What does 0233 mean?
This invalid parameter setting alarm occurs when initialization bit 0 is set to 1, and the number of velocity pulses configured exceeds the maximum allowable value of 13100. This indicates an incorrect setup for velocity feedback, potentially leading to calculation overflows.
Common Causes
- Expected velocity pulses not received within the defined timeframe.
- Encoder signal interruption or degradation.
- Motor not rotating as expected.
- Excessive lag in velocity feedback loop.
