I recently started a new job running an Okuma V100R and when I try to start the spindle in MDI with the door open, that max speed is only about 45-50 RPM. Anything higher and I get the door interlock alarm. Is there a parameter that can be changed or something else that can be done without disabling the door interlock to get more speed? The vertical that I ran at my previous job you could get a lot more RPM for polishing face grooves and such. The guy that ran it before me abruptly quit and took his secrets with him and nobody knows how he did it.
