For increased safety when the enclosure doors are open, install this optional switch that limits the spindle RPM and automatically pauses any G-code programs that may be running. Even when not running a G-code program, your PCNC 440 is still capable of movement — such as jogging or MDI commands — when the enclosure doors are open.
By default, this switch limits the spindle speed to 1000 RPM whenever the doors are open. You can change the limit value from 0 to 10,000 RPM.
Some assembly required.
