(b) Home position return operation
The home position return operation from the position board is basically the same as operation for using
a rotary servo motor.
However, note the following.
1) When using the absolute position type linear scale, the scale home position signal detection method
or the scale home position signal detection method 2 cannot be used.
The other home position return methods are available and a home position return is performed to the
reference home position created based on stop interval settings for the home position return.
2) When using the incremental linear scale, it is recommended to use the scale home position signal
detection method or the scale home position signal detection method 2. In this case, the home
position return is performed based on the home position signal (Z-phase). The reference home
position which is created based on stop interval settings for the home position return is not used.

Note 1. *: Setting will be valid at system startup.
3) When using the incremental scale, the home position return using a Z-phase detection method
cannot be used.
4) With the incremental scale, when using a home position return method other than the scale home
position signal detection method or the scale home position signal detection method 2, "1
"
(Search again) must be set for the parameter No.0240 (*OPZ1).
In this case, the home position return is performed based on the home position return reference
position which is created based on stop interval settings for the home position return and the home
position signal (Z-phase).
