25
OverSpeed Limit
Allen-Bradley · PowerFlex 700
¿Qué significa 25 ?
Functions like Slip Compensation or Bus Regulation have attempted to add an output frequency adjustment greater than that programmed in [Overspeed Limit]. This occurs when the drive tries to exceed its configured maximum speed due to an external force (overhauling load) or control algorithm, potentially leading to instability.
Causas comunes
- Motor speed exceeds the configured overspeed limit (e.g., P3-02).
- Runaway motor condition due to loss of control.
- Incorrect encoder feedback indicating higher speed than actual.
- External control signal commanding excessive speed.
