Replacing the Y Axis Incremental Encoder [03052657-xx]
Parts, equipment and tools
▪ Incremental encoder: read head RSF MS20.xx M Y axis [03052657Sxx]
(contains: read head [03052657-xx], mounting bracket with end stop edge [03051136-xx])
▪ Read head test device PG-U (MS20.xxM) [03071361-xx]
Overview
NOTICE
Scale.
This incremental encoder can be used for the white/silver and for the gray/golden scales.
1. Y axis incremental encoder
Each gantry has two incremental encoders for the Y axis.
These are fixed onto mounting brackets.

Removal
► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthorized
reactivation. Observe the instructions in section "1.2 Preparatory Work..." [ ➙ 13].
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following instruc-
tions:

CAUTION
Mounting bracket without end stop edge
There are two versions of the mounting bracket. If you are using a mounting bracket without
end stop edge, please observe the following instructions:
► If you want to refit the same incremental encoder later on (e.g. for cleaning purposes), do
not loosen the mounting bracket!
► If you fit a new incremental encoder, use the mounting bracket provided (with end stop
edge) to simplify installation.
► Mounting bracket without end stop edge (old):
Loosen the two screws (1) fastening the mounting
bracket on the incremental encoder (2).
► Mounting bracket with end stop edge (new):
Where necessary, loosen the two screws fastening
the incremental encoder or mounting bracket.
► Unthread the cable (3) as far as the next connector or
sensor module and then unplug the connector. You
may want to mark the connector positions, to make
clear assignment easier later on. If you need to open
the cable ties, you may want to mark their positions
as well, for easier replacement later on.
CAUTION
Installation instructions
► Clean the reading surface of the incremental encoder with an optical (lint-free) cloth and
ethanol or with a cleansing tip.
► The incremental encoder needs to be fitted at a distance of 0.75 mm parallel to the scale.
Use the plastic foil scale supplied to check this. Make sure that this distance is kept along
the whole width of the incremental encoder and then check the track signals with the track
signal tester.
► If you are using a new mounting bracket, you will need to press the incremental encoder
against the stop edge during installation. This ensures that you achieve parallelism.

Overview
Removal
► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthorized
reactivation. Observe the instructions in section "1.2 Preparatory Work..." [ ➙ 13].
► Remove the cover above the gantry interface. Depending on the version this is secured with press
studs or screws.
► Loosen the connections on the pneumatic hoses which lead away from the gantry interface.
► Unplug the electrical connections of the Y trailing cable on the top side of the gantry interface.
► Loosen the four screws fastening the gantry interface.
► Unplug the electrical connections on the underside of the gantry interface and remove the interface
from the machine.
