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
