Need Help

I am facing problem with Servo Drive MR-J2S-60B, MR-J2S-200B, MR-J2S-20B, MR-J2S-40A.
The problem is =

Al E9 - "Main Circuit off warning"
both main and control have power supplied and charge led is on.

I suspect there is abnormal chip on control board but don't know which one abnormal chip.
I ever change only control board MR-J2S-200B with another servo drive in same type and the result is ok.

I need help some body to find out abnormal chip cause Al E9.

Thank you for any helps
Best Regards

Hi

I also have such trouble with J2S-10A/20A/60A amps.
Al.E9 is displayed.
The J2S software shows that main curcuit voltage is 160-170V. But actually it's 306-320V. It can be measured between N and P pins on 6-pin connector.
