Velocity Loop Proportional Gain Overflow

Hva betyr 0445 ?

This invalid parameter setting alarm indicates that the internal calculation value of the velocity loop proportional gain has overflowed. This typically occurs when the parameter setting for the proportional gain is excessively high, leading to calculation errors.

• Proportional term in the velocity control loop has exceeded its maximum allowable value.
• Sudden changes in motor speed.
• Inadequate velocity loop proportional gain (P04-10).
• High frequency noise in velocity feedback.
