this is fanuc control OTTC Mori seiki ZL 45 cnc lathe machine. first we found an alarm ex451, during the time, lubrication pump and cooler unit no work. but if we check, there is no any failier, cooler also working properly if bypass line. Now switch on the machine just we could not go inside only showing boothing scree with message is "not ready"
i checked relays (good) but no on running mode because i feel no passing message from the board. i feel that's why no running cooler and lubrication pump. I dont know much about, please anybody can help me to solve this problem.
thanks.

if not ready is comming at booting screen means your systme hard ware is failed for FANUC 0TTC controll.

You can find 4 system PCB inside ur electrical cabinet. removed i/o board and power on machine. if same status is comming then your system hard ware might me having problem.
