hello all, i'm new to the fourm. i have a kitamura mycenter zero and i am getting a servo y axis alarm. the alarm on the servo says -bb? it's a yasnac control and i am running a rotary phase converter. i think it could be a voltage problem. i measured the voltage and the company where i work and it is at 208V steady. my voltage is 255V please help if anyone can tell me what's going on.
