Hi
I have milling center Shizuoka B3V 410 with fanuc OMc.
When I press "power on" on my pcb (A20B-2000-0180/03A), only leds flash L4, L5, L6 leds. Monitor display anything. System is dead.
I checked power supply and battery, all voltage on carts are correct.
Input module is ok - green led.
I checked all switches, limits, sensors - are ok.
If I disconnected all card on master pcb only L4 light.
L4 is off if I mount memory and I/O card.
L1, L2, L3 not flashed ever - it is normal operation??
I have NC/Diagnostic parameters. Ladder PMC is in eeprom.
Please help, I don't have ideas.
