I have an Okuma & Howa ACT5L Fanuc 6TB, turned off at night no problem. In the morning I couldn't start it up. Showed alarm 401 (not ready). If any one who knows or had this problem before please help. I do appreciated.
Something in the boot-up sequence did not fire up and missed giving an OK signal back
check for oil levels, air pressure, hydraulics, cables connected, even an overtravel condition.
Even check all the E-stop buttons ( someone may have hit one by accident )
