Hi!
Little problem with maho 600e
When I try drive machine reference. X and Y axis works well. Z axis won't move and gives this Z09 error.
About 1.5 year ago machine does this same error.
Last time I cleaned glass scale, cleaned motor and tachometer brushes but It doesnt helped. Still same error.. 
I took each relay off, put it back in and manualy pushed motor contactor couple of times. This helped and error dispeared.
Maybe there was a touch fault somewere..Machine have worked very well with out errors about 1.5 year.
But now it started do that same Z09 error again. 
When I try rotate X axis motor by hand it wont turn when machine control is on but Z axis motor turns lightly by hand as if its control voltage were not on.
Could somebody help me ? What could cause this error?
