Once you see what happens to a motor with voltage imbalance, you will want to see it CLOSE.ДЄs well, you will notice that voltage not stay balanced with load. The ONLY thing 'CNC' about an RPC is the way it is tuned. I will take the PSM apart to have a look.Д¬ould wrong Phase rotation cause this problem? Any other insight? Thanks again. The 24V and 5V pins show to within range. The unusual thing is the check of IR and IS current on the PSM check pins show very little current, even when the contactor engages and the alarms sound. My phase converter voltage is 218,219,221. And that causes are either imbalance on the mains, wrong ac reactor, or problem IGBT transistor.

The servo maintenance manual says if you have 30 on spindle amp and 01 on PSM, concentrate on the PSM.

I get a al-30 on the spindle amp and al-01 on the power supply module. I ran spindle to top for 10min yesterday and got nothing. Most of the threads I have found are getting this alarm while spindle is running. If I don't get the alarm at boot up, it runs fine. The overcurrent alarm only happen when the main contactor engages.

I've checked the amps and all have 0's or -'s so the alarm must be on the servo motor itself. And I'm getting a reoccurring alarm 436 soft thermal (OVC). I have a Miyano BNE-51SY with a Fanuc 18i-T control. (26) SRVO-046 OVC alarm (Group: i Axis: j) (Explanation) This alarm is issued to prevent. FANUC Robot series RIA R COMPLIANT R-30iA Mate.
