I powered up the unit the three gecko's fault lights dissapeared and I started tuning my servo motor connected to my z axis drive. No other motors were connected at this time. A couple of times I faulted the z axis by running at too high rpms, nothing major.. I played around with gain and damping till I was happy. When I looked back at the enclosure the x axis had faulted for some reason. I had tested but not tuned the x axis earlier and all was fine.

Yes, of course. When a move is commanded, an offset is added to an
accumulator in
the drive. it expects a corresponding movement of the motor to produce
encoder
counts to decrement the accumulator value. If the accumulator counts up
or down
to 128 counts from zero, it causes a fault. (It may also fault if the
error is not cancelled
within some time limit.)

But, a reset or power down should clear this.
