Hi guys,

We're having some trouble reading the X and Z axis encoders on our lathe.

The encoders for the X and Z axis servos are Yaskawa TFUE-25ZC7 encoders, which are single-ended encoders with an integral tach generator built in.

The outputs of this encoder match Figure 4 shown on page 8-25 of the installation manual, and have been wired as illustrated in the example. Viewing the encoder output in Diagnostics shows no movement.

The Y axis encoder has differential outputs and works fine in both directions on the same encoder input as what we have the single-ended encoder wired to now (encoder #1).

The encoders are connected in order per the recommendations in the Setup.exe program, with Z axis on encoder #1, X axis on encoder #2, and Y axis on encoder #3 (Setup.exe asks that the X and Z axes be wired to a lower numbered encoders than the Y axis. Thurston recommended that we wire Z first, then X, and then Y).

So after all of this, the issue seems to be that the encoders that we are trying to use are setup as differential inputs, so how do we change them to single-ended, or which encoder inputs should we be using?

The machine type has been left as "MAGIC" in Setup.exe just as it came from CamSoft. I had changed this to "GALIL" per the installation instructions, but that moved the travel limits to the X and Z axes and messed things up.


Thanks,

John
