Installation
1. 4 x M3x5 hexagon socket-head screws with locking
varnish
2. Z axis drive
3. 2 x M2.5x12 hexagon socket-head screws
4. Motor clamp upper part /DLM3
5. Motor clamp/DLM3 (do not confuse this with the as-
sembly clamp for the Z motor tacho interference sup-
pression board)
6. 2 x M3x14 hexagon socket-head screws
7. Toothed belt
► Switch off the machine and secure it to prevent unau-
thorized reactivation.
► Remove the plugs (motor tacho and incremental en-
coder) from the sockets on the intermediate distribu-
tor.
► Loosen the four M3x5 hexagon socket-head screws
which have been fixed with locking varnish (1).
► First loosen the upper M2.5x12 hexagon socket-head
screw (3) of the motor clamp fitting 2 (4), then the low-
er one.
► Loosen the two M3x14 hexagon socket-head screws
(6) on the motor clamp fitting (5).
► Carefully remove the Z axis drive (2) together with the
cables.
► Insert the Z axis drive (2).
► Make sure that the teeth of the toothed belt (7) en-
gage in the teeth of the motor pinion (1).
► Use the four M3x5 hexagon socket-head screws to fit
the Z axis drive.
► Tension the Z axis toothed belt by moving the Z axis
drive unit upwards and fix the motor with at least one
screw.
► Check the toothed belt tension with the belt tension
measuring device.
