Laserwash 4000 arch index fault

[Danpelligrino]

Hello,


I have a Laserwash 4000 with a Wash World Bridge. We recently replaced the VFD with the updated style because we were having an issue with the bridge motor losing power. It was working for a few months with no issues.

Now, we are getting an arch index fault after every car it washes, and it needs to be reset every time afterward. Sometimes we also get an arch rotate fail code. It's like its losing power sometimes.

Not really sure what is going on with it. I was hoping someone had some experience with this problem.

Thanks!

One other thing I should mention, there's no specific area in the bay where this index fault is happening. It could be anywhere in the bay and this fault happens

We figured it out. It was the arch rotate prox and cord
