Replacing the Y Axis Incremental Encoder [03094996-xx]
Parts, equipment and tools
▪ Select the correct incremental encoder:
▪ If needed, mounting bracket for Y axis sensor [03086842-xx]
▪ Test device PG1-I (MS22/MS30) assembly [03102699-xx]
▪ Ethanol
Isopropanol – IPA can be used as an alternative.
Overview
Removal
► Unplug the incremental encoder press-fit connection from the gantry interface. In this case, make a
note of the position, to make clear assignment easier later on.
► Unthread the connection cable as far as the incremental encoder.
► Loosen the three screws fastening the incremental encoder holder and carefully remove this togeth-
er with the incremental encoder.

Installation
► Clean the reading surface of the incremental encoder with a cloth and ethanol or with a Q tip.
► Fit the incremental encoder with the three fastening screws. To do this, place the thickness gauge
provided between the incremental encoder and the scale, so that there is a gap. This gap must either
be 0.4 mm (golden scale) or 0.75 mm (black-white). Use the corresponding thickness gauge (plas-
tic).
► Reconnect to the electricity supply.
► Check the track signals with the testing device. (See "4.1.4 Track Signals and Zero Pulse" [ ➙ 143])

Track Signals and Zero Pulse
Check
Proceed as follows to check the zero pulse.
► Switch off the machine.
► Unplug the incremental encoder from the head board or the gantry interface and connect it to the
test device. (See "4.1.4.1 Test Device PG1-I (MS22/MS30) [03102699-xx] – Operation" [ ➙ 144])
► Move the head or gantry manually back and forth. This movement enables you to read the correct
track signal progress from the test device.
► If the track signal is not within the tolerance range, you will need to reset the incremental encoder.
The incremental encoder has then been fitted either too near, too far away, inclined and/or displaced.
CAUTION
Make sure that the cables do not rub against anything.
Make sure that the axes can be moved without damaging the cables.
► Fasten them with cable ties.
