So,
New to us Okuma ES L8 Lathe. Built 2000, OSP-U10L Control. Saw it run in the previous owner's shop prior to purchase. Control wired 220V 3Phase.
Got it in, hooked up air and wiring (actual voltage here is 236 well balanced between phases). Everything in the control comes up nominal except the MPS10 Power Supply unit. All voltages check well within the acceptable range, but I'm getting a 24 Volt Fault LED on the front, which means the control doesn't boot up.
Causes according to the manual: 1. Over Voltage Of Input > 253 Volts (Input voltages check out at 236 on the leads going into the unit. 2. Over Current of Output. 3. Over Voltage of Output
Since none of these conditions appear to be happening, could there be something else going on? Any Okuma vets run into something like this before?
