Getting a ov error (#4) on decleration , adjusted rh2 acording to flow chart.
It worked for a short time. now has no affect. it will run for a while (makes noises while speed changes - from inverter) and eventually shuts down.
Incoming power within specs and tightened all connections.Had drive belts changed as well. Could it be the thermo relay?

[underthetire]

Thermal overload relay won't make noise. AC drive i would assume on that year machine. May have regen resistors for the drive, may be bad transistors in the drive. I've also seen machines with too small input lines cause this problem, and transformers also cause this. What drive unit do you have ?

The machine maintains power when it shutdowns. can reset inverter button. It has a Yasnac lx-1 control and a 626 mt2 b series inverter
