Oct 10, 2018
Ok so i have a lb15 okuma lathe,whenever i give a spindle command the spindle starts to turn then stops and alarms out giving alarm 110 sdu 1, so i have 3 of these lb15's in the shop so i have checked fuses in the drive unit all are good so i swaped drives with a working machine the other machine worked fine while this one still gives same alarm so i changed spindle motors and still yet same alarm i have good voltage at the sdu at 230V and goo voltage at spindle motor fan and it is working i am lost..
