15. USING A LINEAR SERVO MOTOR
15 - 19
The following shows the relation between the stop interval at the home position return and the linear
encoder resolution. For example, when the linear encoder resolution is 0.001
μ
m and the parameter
for the stop interval at the home position return, [Pr.PL01], is set to "_ 5 _ _" (16777216 pulses), the
stop interval is 16.777 mm. The value inside a bold box indicates the recommended stop interval for
each linear encoder resolution.

In the case of a proximity dog type home position return, the nearest reference home position after
proximity dog off is the home position. The linear encoder home position can be set in any position.
LZ (Encoder Z-phase pulse) is outputted based on "Stop interval selection at the home position
return" in [Pr. PL01].
