2-2. Replacing the Motor
2-2-1. Replacing the Z-Motor
After the Z motor has been replaced, it is absolutely necessary to re-input the MS parameters
related to the Z-axis home position adjustment, Z-axis height, and laser.
(For details of input items, see section 2-7.)
1) Disconnect the Z-motor
cables from the power
connector base and
Z-encoder relay board.
(See also steps 2), 4), 5),
and 7) stated in section
2-1.)

2) Loosen the hollow set screws c (×2) of the Z-motor pulley.
3) Remove the SEMS cap bolts d (×3) mounting the motor. Detach the Z-motor by pulling out the
pulley.
4) Reassemble the components in the reverse order of disassembly, and adjust the belt tension
as the last step.

c Put the screw in the tap of the Z-motor and lock the
mounting screw with the screw pulled in the direction
indicated by an arrow with a force of 21.6 N (2.2 kgf)
using a tension gauge.
Tension meter set value (For check)
• Tension meter input value
Weight: 0.9g/m Width: 8.0mm Span: 45mm
• Specification value: 10.5±1N
∗ Apply Loctite 242 to the Z-motor mounting screws
(3 pcs.) and tighten them with a tightening torque of
2.3 N･m.
∗ When tightening the setscrew of the Z-motor pulley, make sure to align the orientation of the
flat part of the Z-motor shaft and the setscrew of the pulley. Tighten the setscrew with a torque
of 0.5 N･m.
When the Z-motor pulley is secured at a position where
the marking on the shaft is located at 2-o’clock position
as shown in the figure on the left or the shaft D cut
surface is located at a position as shown in the figure
with the Z-axis raised to its uppermost position, this
becomes the conditions for item d.
