Hi all, I'm a new poster although I've been lurking for some time. Sorry for the lengthy post.

I have a Miyano ANC-35 with Fanuc 11TT. I receive the following alarms:
SV003 Z1 Abnormal Current
SV004 Z1 Excess Voltage
SV006 Z1 Velocity Unit Power Too Low
(SV006 always follows shortly after the others, perhaps due to the unit shutting down?)

I've also noted the following alarm LEDs on the drive unit:
HC
OVC
TG

Following advice I found on this forum I swapped out the X & Z cables between the two drives to try and isolate the problem. The error stayed with the drive unit which I believe indicates that my drive is at fault and my motors are OK.

My questions: Is anyone familiar enough with this system and drive unit to give me any hints as to how I can diagnose and possibly repair it? If not, do I replace the top board or could the problem be elsewhere in the drive unit?

Axis drive top board p/n:
A20B-1000-0560/10E

AC servos (red caps).

I'm happy to provide any other info necessary.

Thanks,

James
