14-6. Z-θ Unit
The Z-θ unit is composed of an AC servo amplifier that drives the Z/θ-axes.
14-6-1. Structure of Z-θ Unit
The servo amplifier for the Z/θ-axis is a 4-axis integrated servo amplifier that one amplifier board
can drive the 4 axes.
The servo amplifier board for the Zθ-axis is mounted in the head unit. Actually, four boards are
mounted in the vertical direction.
Three boards are mounted only in the KE-3010 (f is not mounted).
Figure 14-6-1-1 shows the relationship among each motor and servo amplifier.
