Connectors
Posted: Fri Aug 11, 2017 10:28 pmI'm gathering parts for a new controller enclosure (24" X 24" X 8" NEMA 3R w/ hinged cover, or 609mm X 609mm X 203mm IP14) and I'm curious as to what connectors people use for their motors, spindle, and other parts. My current machine is based on the CNCRP PRO48X96, and their motors either come with DE-9 (Nema 23) or XLR-4 (Nema 34), but this isn't really an industry standard, is it? Their sensors and E-stop use M12-4A, which seems to be fairly common. The spindle and plasma share a "standard" 14 pin circular connector, and from the VFD to the spindle an M23-6 is used. I'm considering getting rid of all but the M12's and just using cable glands at the controller and terminating everything on a DIN rail terminal block. This would allow me to upgrade from Nema 23 to 34 without having to re-do all of the motor connectors the enclosure, and I'm guessing it'd work for servos, too.
So my question to those of you with multiple machines, or people that have fallen down the upgrade hole, what did you use? And while we're talking about controller enclosures, what about dust collection, air/coolant, and any other extras? My plan is to use dry contacts to trigger dust collection as well as air/mist/flood coolant and either RJ45 jacks, or again, cable glands + terminal blocks instead of switching line voltage at the enclosure. Modbus/RS485? RJ45.
Any suggestions or things you would have done differently?
