26

Regen Timeout (Adv. Code 0)

Vacon · X4 AC Drive

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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

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