If the power goes out, during the restart I get E070 execution inactive then E684 impossible operation. Which means I have lost my reference. My U axis is off by
aprox. .750, So I do a guide setup and life is good till the next time. Some times the machine will shut down, startup , shut down and start up when either the generator
or the pumps kick in with the same end result. I have replaced the K1 relay and went through all of the YV valves.
Any suggestions would be appreciated.
