Machine Velocity Feedback Coefficient Overflow

Hva betyr 0886 ?

This invalid parameter setting alarm indicates that the internal calculation value of the machine velocity feedback coefficient has overflowed. This usually happens if the coefficient is set too high, exceeding internal processing limits.

• The calculated machine velocity feedback coefficient is too high.
• A sensor reading related to machine speed has overflowed during coefficient calculation.
• Parameter P601.2 (Velocity Feedback Coefficient) is set too high.
• An internal process overflowed during the calculation of the velocity feedback gain.
