24

Decel Inhibit

Allen-Bradley · PowerFlex 700 AC Drives

What does 24 mean?

The drive is not following a commanded deceleration because it is attempting to limit bus voltage. This indicates the DC bus voltage is rising due to regenerative energy, potentially exceeding safe limits and causing the drive to inhibit deceleration.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Disable bus regulation and/or add a dynamic brake resistor and/or extend the deceleration time parameter.
