I've got an Okuma MC-4VA with a "201-Z Alarm A Servo Amp 2E6" alarm that I can't get it to reset.
- There is a page for Alarm "201" "Alarm A", however I can't find anything about a "201-Z" or "Servo Amp 2E6".

Opened up the rear box and there are no lights on on the Z-axis "BL-D(30)A" control board.

There IS power going to the connectors from the DC-Power Supply board, regardless of whether the breaker to the right of the DC-PS is turned on or off.
- However, the voltages do seem to vary once the breaker is turned off.

According to the manual, if when the breaker to the DC-PS is turned off and the green light stays on, then the DC-PS needs replaced.

A few questions that I can't seem to find through searches or the manuals:
- If the DC-PS is bad, how is it still powering X & Y?
- Is there a way to double check the DC-PS to know that's what is at fault?
- Is there a fuse on the DC-PS that I should check?
- Can a bad motor cause the above error?

Talked to a tech and they suggested that if the DC-PS had lights that it'd be the Z-axis drive.

I had it quoted at something just under $5k. Checked on Ebay and found a Y-axis for around $700. All the numbers matched the Z-axis.

I purchased and installed it and it's now currently running.

Anyone know of any good places to repair the old drive?
