General Mach Discussion / Encoder wiring on OLD machine.
« on: January 05, 2011, 02:49:26 PM »
I'm currently replacing a old Allen Bradley Bandit 3 setup with MACH3 software on a early 80's vertical mill. I realize a lot of hardware will need to be replaced, but I'm taking it step by step.
This is for a mill for personal use, so budget is limited and time isn't very important.
Step one is to get the encoders to read on on Mach 3 software.
There are rotary encoders on the ends of the motors. They have 6 wires coming out of them. Twisted pairs red-white, black-white, brown-white. How can I meter these or make a setup to figure out which ones are which? Or do I need to take them apart to see where the wires end up going. These were going to the computer board on the control unit. There is a seperate tach signal that goes to the servos.
I build electronics for a living so I have access to any testing stuff I need.
Thanks
