<Replacing the timing belt Z IC>
After the timing belt Z IC 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 2-8.)
1) Loosen the screws
shown in the figure on the right.
2) Replace the timing belt Z IC.
3) Reassemble the components in the
reverse order of disassembly.
∗ Apply Loctite 242 to the Z-motor
mounting screws (3 pcs.) and
tighten them with a tightening
torque of 2.3 N⋅m.
∗ Adjust the belt tension following
section 2-2-3.
<Replacing the timing belt θ: KE-3020V>
After the timing belt θ has been replaced, it is absolutely necessary to re-input the MS parameters
related to the Z-axis home. (For details of input items, see section 2-8.)
1) Detach the bearing base L
2) Detach the spline shaft from the
coupling .
3) Pull out the spline housing downward
and the spline shaft upward.
4) Replace the timing belt θ.
5) Reassemble the components in the
reverse order of disassembly.
∗ When the bearing base L is secured,
make sure that the shaft is rotated
