When you replace the existing Z-motor with another one, you have to obtain the MS parameters
related to the height of the Z-axis and the laser again. (See Section 2-2 “Readjustment after
Replacement of Head Unit” for the MS parameters to be obtained again.)
<Motor arrangement>
The odd-numbered shafts of Z-motors are arranged on the upper side, while the even-numbered
shafts of Z-motors are arranged on the lower side.
Note that the motor replacement method differs between odd-numbered shafts and even-numbered
shafts.
