0694
Velocity Feed-Forward Coefficient Overflow
Fanuc · Alpha i Series Servo Amplifier
Hva betyr 0694 ?
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.
Vanlige årsaker
- Velocity feed-forward coefficient calculation has overflowed.
- Problem predicting velocity response to torque commands.
- Incorrect velocity feed-forward gain settings (e.g., P04-17).
- Unanticipated changes in motor speed.
