Difference between
position at switch-
on and shutdown
When the MANUALplus 620 is switched off, the actual position of the axes is
saved with an absolute encoder. During switch-on it is compared with the
position values read by the encoder.
If the positions differ by more than the difference defined in MP_endatDiff, a
pop-up window appears with both positions. The new position must be
confirmed with a soft key. If it is not confirmed, the error message Check the
position encoder <axis> appears.
The pop-up window may appear, stating that the positions at switch-on and
shutdown differ by more than MP_endatDiff. If the motor is located at the
correct position, you can confirm the message.
MP_endatDiff
Permissible difference of EnDat encoders during switch-on

The cause for one of the above listed messages can also be a defect in the
encoder or control.
