Came into to work this morning with my Cadet 4020 (OSP 5020M) displaying units in Metric. Checked my parameters and found the "Data Set Unit", under the : "Input Unit System" page in parameters had switched to metric (pic attached). Switched it back to inch and re-started the machine. It went back to metric. I can switch it to Inch run parts just fine, but every time it is shut down it reverts to metric. I don't recall changing any settings or parameters last friday, so no idea whats going on. I am not an Okuma expert, learning this machine/controller as I go. Any ideas?
Thanks,
Dan
