Dear Sirs,

I have a Mitsubishi MR-JE-70A Servo amplifier which gives an alarm "AL 8A.1" when power is on. (please see attached photos)
When it resets it indicates again.
The Servo drive is not designed to communicate with any controller, It just receives control pulses from a PLC.
What is the meaning of this alarm and how to repair the servo amplifier.

Thank you
Viraj Prasanna Gunawardana
