Keith,
The PCON signal switches the drive from PI (proportional-integral) to proportional only. The PI mode is preferred as it gives better speed control, but I don't know off hand if the signal on this drive needs to be on or off to enable this mode. I think you should try dropping the encoder count out of the drive just to see if this helps. You probably can drop it quite a bit without hurting your machine accuracy. Other than that, it doesn't really sound like a problem with the drive.
