Technical Q & A
*Note: On ShopBot desktops and MAX, the RPM must be manually adjusted.
The Spindle RPM Control window needs to be open in order for the spindle to change speed. If you see this window pop up during the warm-up routine or software start-up, do not close it. To open it manually, type TR in the ShopBot console (the blank box next to the ShopBot CNC logo). Click on RPM to open the fill-in sheet, and make sure that the correct VFD is selected. Start when SB3 start is set to 1, and the Hz scale is set to 60 for a V1000 spindle and to 100 for a 74X spindle.
The RPM Control window is not available on software versions earlier than 3.6.X.
