Hi Guys
We have Nachi AR type controller, since last month I started getting error E0028- Servo Error ( on all axis) : Drive unit voltage down frequently.
While in operation robot will stop at same position at least couple of times or even more when it happens it stops 2-3 times in a row. So once it happens you restart and it stop again straight next time, this happens once or twice per shift any time of shift.
We have recently changed encoder battery, I have seen the manual for this error code and its very hard to check the voltage as it does not show any drop in voltage. Does any one has encountered this error and what's the good fix so that it doesn't happen again.
Thanks in advance!
