Is it possible, that the encoder on a yaskawa servo motor, can allow the axis to move, without showing up in the readout? My Y axis has a ballscrew, and is driven by a yaskawa brushelss servo motor. when I run a series of holes, just using the x axis, the y axis moves over toward home, .0008" per cycle. After about 50 cycles, I am out of tolerance, and the movement never showed up on the display. I am using Camsoft professional software.

What controller do you have? Do you have differential or single-ended encoders? Have you discussed your problem with Camsoft?
In your "display" are you displaying TP or RP data? What is the position error (TE) when you are out of tolerance?

I have a DMC-2152 controller. I have moved everything out of the cabinet, to eliminate electrical noise. I also installed ferrite cores, on the cables. I have Yaskawa SGDH-04AE amps. Is it possible, that the amp isn't sending all the encoder pulses to the motion card, or maybe the card is not able to handle them? My encoders are motor mounted incremental encoders. 2048 ppr x 4

The controller can handle up to a 12MHz encoder frequency, so it will be able to handle your encoder.
