Phase Z signals are output as is if the encoder of the actuator is not a
serial encoder. With serial encoders, the range of ±0.5° in mechanical
angle from the position of point 0 (home) is output as phase Z signal. This
precision is only guaranteed when the revolution speed of the motor is 100
rpm or less due to the communication cycle with the encoder.
* See (7) for the encoder types.
