Bridgeport Boss brake code
Posted: Wed Aug 03, 2022 8:24 pm
I have just about finished a Bridgeport boss rebuild with new DMM motors that bolt on and an oak board. I have all the axis moving but working on peripherals. I wanted to keep the speed control and brake solenoids that exist and hoped to run them through the output 9 brake setup as per schematics. It appears this is set up a little different than I need. The plan is that the brake solenoid will be activated when the spindle is inactive. When the spindle is turning the solenoids for the speed control and brake should be set to supply power to air powered spindle speed change solenoid thru the original switch on the mill and the brake will be inactivated during spindle movement to allow the spindle to turn. I found a previous thread that alluded to this setup but it was on another board and I wasn't sure how to do it. i have reset the VFD to coast to stop. I am aware that I will probably need to alter my plc program but have little experience. I down loaded note ++ and looked at the plc program but it is greek to me. Recommendations - thoughts?
