6.6.2 Setting external position measuring system
A) Distance sensor / tape
The sensor is mounted parallel to the tape and positioned using a feeler gauge.
The distance between the sensor and the tape varies depending on the type
used. The value can be found in the table below.

B) Setting the reference point
The distance between the mechanical stop and the index on the magnetic tape
must be set to the distance according to the following table.

This must be done so that when referencing the axis, an index is not detected
too early or too late. This would then lead to a position shift according to the
pole pitch of the tape.
Procedure for setting the distance:
1. Configure the system as described in the LinMot controller manual. Set the
Home Position to 0 mm.
2. Reference the axis.
3. De-energise the axis by removing the switch ON-bit.
4. Press the axle by hand against the mechanical stop.
5. Adjust the actual position by moving the sensor so that the distance to be
set appears with a negative sign (e.g. Home Position=0mm
Actual
Position = -0,5mm).
Note:
If the home position is set to a different value, the corresponding
offset must be taken into account for all masses (e.g. Home
Position=50mm
Actual Position = 49,5mm). If the axis is set to "positive
homeing" the distance must be added (e.g. Home Position=500mm
Actual Position = 500.5mm).
6. Set new axis reference position.
7. Move the axis to the mechanical end stop so that the current reaches the
maximum value. Then check the setting (e.g. -0.5mm).
The desired distance is set.
