Re: Okuma LB12 100-3 alarm dif over
I don’t believe that those alarms are caused by replacing the motor unless something else is wrong. You should normally see OVERFLOW on your position page and correct the encoder reading by setting the PR ZERO OFFSET in your system parameter page. Only alarm should be over travel or such and not velocity or DIF.
Check your encoder feedback in your actual position page where you can see RAPA, RCON, and RDIF. DIF should be 0 or almost 0. CON is the commanded value and will be constant. APA is the active position so DIF=CON-APA. APA should only be twitching a tenth or 2. If not, the you may have a faulty encoder or wiring.
