QA Table
The encoder must be installed in complete alignment with the spline housing IC assembly to prevent an
excessive load from being applied to the flat spring of the encoder. (LAIC only)
Secure the encoder so that rotation of θ-axis (spline housing IC assembly) does not result in load being applied to
the encoder.

Raise the Z-slide bracket up until the Z-sensor is activated. From that point, raise the Z-slide bracket another 1
mm to obtain phase zero of Z-motor. Secure the coupling at this point.
Lock the Z-motor with its phase zero obtained and raise the Z-slide bracket. When the Z-sensor LED lights up,
raise the Z-slide bracket another 1 mm and, at that point, secure the coupling.
Make sure that Z-sensor is activated when the Z-slide bracket is raised to its upper limit.

Check procedure:
Tension value: 34.6 N {3.53 kgf} Timing belt θ tension adjustment value
Adjust to obtain a deflection of 1.2 mm when the center of the belt is pushed with a force of 2.2 N {220 gf}
using a spring balance.
Center-to-center distance 78
Adjustment procedure:
Loosen screws (a) at four places and adjust tension in the belt with screw (b). After the adjustment, tighten
nut (c) and bond hexagon cap nut (d) with Loctite 242.
