13-6. Z-θ Unit
The Z-θ unit is composed of an AC servo amplifier that drives the Z/θ-axes.
13-6-1. Structure of Z-θ Unit
In the AC servo amplifier for the Z-θ unit, one driver can drive 4 axes. Therefore, 3 drivers are
installed in FX-3.
4-axis integrated type servo amplifier board for the Zθ-axis is mounted in the head unit. Actually,
three boards are mounted in the vertical direction.
Figure 13-6-1-1 shows the relationship among each motor and servo amplifier.

13-7. Transport Unit
13-7-1. Structure of Transport Unit
Table 13-7-1-1 shows the structure drawing of the transport unit.
The BASE-CARRY board is mounted at the front right portion under the base frame and the driver
for the stepping motor (for transport, auto PWB width adjustment, and backup) is mounted at both
the front left and right portions.
It is not necessary to change the connection destination boards of the transport L motor, transport
R motor, transport L sensor, transport R sensor, and WAIT sensor inside the transport unit
according to the reference and flow direction.
