Hello,
I have a problem with Okuma LR10 MY1990. I send motor from M axis BL-S125E-60T with BL-D 150A drive to check out what's wrong because after years good job suddenly I get APA CHECK fail. Service repair BL-D test it and everything is good but I get back info about encoder-it's bad. Service change bad to new one in accordance with the type plate, because the one that was mounted isn't normal Okuma's encoder[service opinion, google etc.](attach photo)and machine don't work with new one (SVP Start alarm). I don't have electrical drawings, special specifications etc.. Maybe someone know what's wrong and help me, every EU services are helpless.
