Cause : Decel Inhibit comes when the drive is not following a commanded acceleration or deceleration because it is attempting to limit bus voltage.
1. Verify that input voltage is within drive specified limits.
2. Verify that system ground impedance follows proper grounding techniques.
3. Disable bus regulation and/or add dynamic brake resistor and/or extend deceleration time.
