I have a Smartrise control with a magnetek HPV 900 drive with a regen drive on a gearless Torin machine and I'm getting a overvolt fault on the drive in the up direction empty car. The job has been turned over to the public for about 2 weeks now. When we first tried to run this car on auto during the mod we had the same problem but it went away . Now it's back has anyone any suggestions.
