Installing the primary part of the linear motor
Settings
4-12: Replacing the linear motor primary part (D4)
X Fit scotch tape to the lower edge of the primary
part of the linear motor, so that the lockrails (5)
do not fall out during assembly.
X Push in the primary part from the side.
X Fasten the primary part (2) with the nine M5 x
20 hexagon socket-head screws (3) to the
motor bracket (4).
X Make sure that the primary part is aligned in
parallel to the permanent magnet.
X Fit the X axis motor unit as described in sec-
tion (4.1.2.5 Replacing the X Motor Unit
[00333167-xx]

37 ) .
X Fix all the cables with cable ties.
CAUTION:
X Make sure that the cables are firmly
seated. Otherwise, the high
acceleration forces may cause the
cable to slip out of position and shear
through.
X Fit the permanent magnets (4 or 16 M6 x 12
hexagon socket-head screws). The space at
the bottom must be 0.8 mm. Use the
appropriate feeler gauge or plastic strip to help
you. A gap of approx. 0.8 mm should be
between the magnet plates.
X Fit the cover strips on the crossbeam above
the gantry concerned (3 M6 x 8 hexagon
socket-head screws).
4-13: Replacing the X-axis motor unit (D4)
X Use the belt tension measuring device to set
the X-axis toothed belt tension to 44 Hz + /-1
Hz.
CAUTION:
X Do not overstretch the toothed belt
when adjusting the belt tension.
X Secure the M4x35 hexagon socket-head
screw (2) with the locknut (8).
X Check the axis dynamics of the drives
removed.
