Velocity Feed-Forward Coefficient Overflow

Fanuc · Alpha i Series Servo Amplifier

Was bedeutet 0699 ?

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.

Häufige Ursachen

  • Velocity feed-forward coefficient calculation has overflowed.
  • The system is overcompensating for expected velocity.
  • Velocity feed-forward gain parameter (P04-17) is too large.
  • Fast dynamic response is causing calculation instability.
