Regen Timeout (Adv. Code 0)

What does 26 mean?

This fault occurs if the drive takes more time to decelerate the motor to a stop than is allowed. The timeout is determined by the longest deceleration ramp time (Decel1 or Decel2) plus the Regen Timeout parameter. This typically indicates an excessive amount of regenerative energy during deceleration.

Complete Troubleshooting Guide

1. 1

   Reduce the amount of regenerative energy by increasing the deceleration ramp times (Decel1 or Decel2) to allow for slower stops.

2. 2

   Increase the value of the Regen Timeout parameter to provide more allowance for deceleration in high-inertia applications.

3. 3

   Consider adding external dynamic braking resistors if regenerative energy is consistently high and ramp times cannot be extended.
