Can a kinetix servo motor 'drift' without a fault
Can a kinetix servo motor 'drift' without a fault
(OP)
we have a machine that has been running approximately 6 months. it has 4 servo axis and one seems to be going out of position but without showing an error. The axis in question seems to always be advancing the other axis. we have changed both the motor and cables. Conceptually, does anyone know is it possible for the drive to be 'loosing' encoder counts which would in turn make the physical axis advance its commanded position?

If you can use an oscilloscope on the encoder outputs you may see it's very noisy or there is too much capacitance on the leads causing distorted waveforms, etc.
Could be your hardware or software too. You may be driving too fast and some part of the system is just not up to the task.

The problem was very misleading but it did end up being mechanical slippage but on a different axis from the one that appeared to be going out of time.
During fault finding all mechanical components were checked (on the axis we thought had the problem) thus leaving only the electrical servo components to be in question. this is where the question 'is it possible for an AB kinetic drive to loose encoder pulses and not fault out'
