Hi guys, i have a problems with a okuma lathe LB 25, its has OSP 5020L controler, well one day we have a low voltage and its get alarming "110 ALARM-A 1", and then we can´t operate the machine, i look de alarm manual and its says.. check EC inpot N8 bit 5, check the lamps on the SDU PCB. so i don´t know if its damaged the VAC Unit Driver or somthing else. i inspect all the fuse in the electric panel but all its ok, only two in the unit driver.
