19.2.10 Resetting the machine datum
If an axis motor was replaced whose motor encoder is used for position capture (indirect path
measurement), the machine datum (machine reference) may have to be reset.
The procedure for restoring the machine datum when using indirect encoders is the same as with
direct encoders. --> See ”Resetting the machine datum” on page 19 – 295.
Special case: Double reference run
(If you have exchanged a motor with an EnDat encoder which is used for the first rough reference run;
no changes were made to the position encoder.)
General procedure:
8 Reset MP1355.x for the respective axis to 1 (= double reference run) and MP1356.x (distance
between speed and position encoder for double reference run) to 0.
8 Reboot the control.
8 Confirm the position message of the EnDat motor encoder.
8 If required, expand the traverse range.
8 Slowly and carefully traverse the reference mark of the position encoder.
8 The message Set MP1356.x to <value> appears.
8 Note down this value.
8 Enter this value in MP1356.x.
8 Reset the traverse range to its original value.
8 Test the entire reference run of the machine again!
Further information --> See ”Reference run” on page 20 – 323.
19.2.11 Restoring the spindle orientation
If you have replaced a motor encoder used for oriented spindle stop (e.g. for tool change), you must
now readjust the spindle preset.
The procedure for restoring the spindle orientation when using motor encoders is the same as with
angle encoders. --> See ”Restoring the spindle orientation” on page 19 – 299.
DANGER
Ask the machine manufacturer for the reason why a double reference run of the machine axis was
configured! The double reference run may be required to avoid collision. Follow the instructions
of the machine manufacturer to restore the double reference run.
