0695
Velocity Feed-Forward Coefficient Overflow
Fanuc · Alpha i Series Servo Amplifier
What does 0695 mean?
This invalid parameter setting alarm indicates that the internal calculation value of the velocity feed-forward coefficient has overflowed. This typically occurs when the coefficient setting is too high for the system's internal processing limits.
Common Causes
- Velocity feed-forward coefficient calculation has overflowed.
- System unable to accurately predict velocity based on torque.
- Velocity feed-forward parameter (P04-17) is set too high.
- Rapid acceleration/deceleration transients.
