Tree used some BEI encoders that are difficult to find any datasheet for. The numbers on the case are 817-05-1019 CI;OB0068 S/N 106470 . These are the encoders that came on the Baldor motors and I assume they are original. ZPS was not able to ID them. They have 9 wires 5V,COM, A,/A B /B Z /Z and a BIG Ground wire.
They were used on a retrofit using Gecko G320 and Mach3. After reviewing the controls I had made some errors - left the jumper on the G320 between pin 5 and 7 meaning that any possible error correction was disabled. Before going to Retrofit 2.0 I wanted to get everything corrected since I would have to do it for a new controller. After removing the jumpers the machine was completely unstable - erroring for a variety of reasons ... so the plan is the shield all wires, do whatever I can to reduce noise and get the system operational.
Rather than go into the larger picture I want to ask about the encoder wiring. For some reason - which seemed to work, I used /A and /B. Now that I'm using A and B I have a runaway servo, so I will go back the way it was. I just doesn't seem right.
Any advise on removing the encoders would be welcome - there are three screws with triangular clamping items but I 'm guessing there is some set screw that holds the encoder to the motor shaft.
