So we have a Hitachi Seiki HT20 Lathe with a Fanuc 3TF control. Yaskawa Spindle Drive. Running fine and this morning I came In and fired It up. Put It In warmup and walked away. Came back and I have the Red Motor LED on the control Lit. Machine In the Not ready state. Nothing tripped. It has two DC power supplies In the back cabinet. One is a 12V the other is a 5V. Good AC power going In. Neither produce 5V or 12V. Seems odd to me they would both die at the same time? Could something else have wiped them out? Any Ideas at what else to look at? Or would you just replace the supplies and see what happens?
Pulled all the outputs to make sure something else wasn't pulling these down. Still good 115VAC Incoming. Nothing on the DC outputs.
