Cause : Soft Charge Answerback Fault comes when there is damage to the relay or contactor on the soft- charge bypass relay.

  1. Re-energize the drive. 
  2. If the fault stays, replace the control board or the drive. 
  3. Monitor U4-06 [PreChargeRelayMainte] shows the performance life of the soft-charge bypass relay. If U4-06 is more than 90%, replace the board or the drive
