Decel Inhibit

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.

• External signal preventing deceleration (e.g., motor brake active).
• Internal logic error during deceleration command.
• Deceleration ramp time set too short for the load.

Click steps to track your progress.

1. 1

   Verify input voltage is within the drive's specified limits.

2. 2

   Verify system ground impedance follows proper grounding techniques.

3. 3

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