(2) Home position return method (Homing method: 6098h)
Address
6098h
Homing method
The current home position return method can be read using the function code "03h" (Read Holding
Registers).
Set a home position return method using the function code "10h" (Preset Multiple Registers). To enable
the written home position return method after turning the power back on, execute the writing command
to EEP-ROM (1010h). After the execution of the writing command to EEP-ROM, the values of [Pr. PT04]
and [Pr. PT45] are changed.
The following table lists selectable home position return methods.

The home position return method specified with [Pr.
-
PT04] or [Pr. PT45] is used.
When the front end of the proximity dog is detected,
Forward
the travel in the reverse direction starts. Then, the
position where the first Z-phase signal is detected is
Reverse
set as a home position.
The position specified by the first Z-phase signal after
Forward
the front end of the proximity dog is detected is set as
Reverse
a home position.
After the front end of the proximity dog is detected,
Forward
the position is shifted in the reverse direction and the
position on the front end (edge) of the proximity dog is
Reverse
set as a home position.
-
The current position is set as the home position.
-
At the front end of the proximity dog, deceleration
Forward
starts. After the rear end is passed, the position
specified by the first Z-phase signal or the position of
the Z-phase signal shifted by the set home position
Reverse
shift distance is set as a home position.
The object is pressed against a mechanical stopper
Forward
and the position where it is stopped is set as a home
Reverse
position.
The current position at servo-on is set as a home
position.
-
A home position can be set without switching to the
home position return mode (Homing Mode).
At the front end of the proximity dog, deceleration
Forward
starts. After the front end is passed, the position
specified by the first Z-phase signal after the set
distance or the position of the Z-phase signal shifted
by the set home position shift distance is set as a
Reverse
home position.
At the front end of the proximity dog, deceleration
Forward
starts. After the rear end is passed, the position is
shifted by the travel distance after the proximity dog
and home position shift distance. The position after
Reverse
the shifts is set as a home position.
