Installing the X-axis motor unit
X When using SIPLACE D1 machines, the heat sink from the old X motor needs to be fitted onto the
new one. For details, consult the corresponding retrofitting guide [00195618-xx].
4-15: Replacing the X motor unit (D4 shown as example)
1 gantry D1 (2 gantries D2)
X Carefully insert the X motor unit (4) as far as
the stop,
making sure that you do not damage the
toothed belt. The motor cable points towards
the permanent magnets of the linear drive.
X Fix the X motor unit into place with the two
hexagon socket-head screws (7).
X Fit the cable holders for the trailing cable (10).
X Fit the board holder (9).
X Fit the X/Y distributor (5).
X Connect all plugs to their sockets on the X/Y
distributor (5).
X Fix the flat ribbon cable with the cable clamp
(11).
X Fix all the cables with cable ties.
CAUTION:
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 Tension the X toothed belt with the hexagon
socket-head screw (2).
X Use the three M6 x 8 hexagon socket-head
screws to fit the cover strip to the crossbeam,
above the gantry concerned.
X Connect the cable of the fan motor to the
socket.
4-16: Replacing the X motor unit (D4 shown as example)
X Push the head mount (1) towards the X axis
motor unit, as far as the stop on the
elastomeric spring.
X Turn the hexagon socket-head screw (2) to set
the belt tension to 44 Hz +/-1 Hz.
CAUTION:
Do not overstretch the toothed belt
when adjusting the belt tension.
X Secure the hexagon socket-head screw (2)
with the locknut (8).
