Hi, I'm looking for some help with a problem on a Z-axis of a Deckel FP4MA.

When I try to move the Z-axis, it will only move a short distance and than the control switches off. After a few seconds I can switch the control on again. It does not make any difference if the movement is in positive or negative direction, by hand or stepping.
The liniar scale is replaced by a new one; the DRO shows the movement of the axis. (the old liniar scale had a problem with the reference mark).

I also see a e1 on the right to the Z-axis. The motor (is the same for Y-axis and Z-axis) is working fine when I move the Y-axis.

Anyone an idea what to check? I already switched the cards for the X en Y/Z but obviously this did'nt solve the problem.
