Modification of Ajax DM45

Post by jcsb »

In between doing a bunch of other things, I changed out the headstock and motor on my Ajax DM45. I am using a Teco L510. I upgraded to CNC12. Before finishing I want to resolve an issue I have. I can run the spindle motor forward and reverse from the control and I can change the speed manually, but I can't change the speed from mdi with a m3 command. I've attached the report zip. Any help will be appreciated.

When you "change the speed manually", what does that mean? Turning a vari-speed crank on the mill head? Pressing the up and down buttons on the face of the Teco VFD? Or pressing the speed up and down buttons on the Centroid jog panel?

When you start the spindle in MDI with M3 S___, what speed does it run at?

Sorry pressing the speed buttons up and down on the the jog panel. It runs in mdi only one speed. Increasing the speed by changing S does nothing. You can program M4 and it reverses but runs at the same speed.

Ok, I guess I’m on my own with this one, unless someone wants to speak up.

You could try installing a more recent and more standard PLC program.
