With the coupling fixing screws (at two places) loosened, move the coupling up and down. Secure the Z-motor
when the coupling can be moved smoothly without binding.
The Z-motor shaft must be aligned properly with the ball screw to prevent an excessive load from being applied to
the coupling.
Coupling

r
Minimizes load applied to the coupling to prevent it from being damaged.

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.

QA Table
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.
