Hi, I have a 1336 VFD drive that would trip out on overcurrent. Replaced the IGBTs and i'm still getting the same fault. I disconnected the motor from the drive and i was still showing current. At 0hz i was seeing around 8-10 amps and at 60hz i'm seeing around .5 amps. I'm looking for possible areas to check out. One thought i have in my mind is that a current transformer might be giving a false reading.
Thanks for the help,
Jeramie
