Hi I have an old Mori Seiki MV 40 A we just acquired and it wont move all the way down the Z axis. It should go down to about 6 inches above the table but wont go beyond about 14 inches. Gives a soft OT warning and then wont move any lower with the handle.

The Z drive was disconnected recently and then put back. It is possible that where it was connected via the belt to the motor before is now a different position. Does the "absolute encoder" term mean that the motor has some limit to travel in each direction built in? In other words if the motor thinks it is lower down than it is, does it stop moving when it gets to a certain point or will it keep driving till the limit switch tells it to stop?

It would be easy enough to disconnect the belt and rotate the motor independently to see if this "range of travel" also moves.

Thank you , V
