checked the literature that i have and can not finding anything about a fault for the output voltage of the drive being over 500 volts. What was the line side voltage feeding the drive and the DC bus voltage?

A co-worker of mine was working on it so i don't have all the info. The chiller itself never faulted. It would just run full speed and sound like it was almost single phasing (best way i can describe) hue found some info and narrowed it down to the trigger board. Thanks for the reply.

if my memory serves me right i think it is usally around 600vdc under 450 and over 745 vdc i think is a problem.
