6. APPLICATION FUNCTIONS
6.21 Absolute position detection system
By using a servo motor compatible with the absolute position detection system, the positioning control can be
made by the absolute position detection system.
In the absolute position detection system, if machinery position is determined at the system startup, there is no
need to execute the home position return because the absolute position is restored at system startup.
Determination of machinery position is made by the home position return. At home position return and power
on, be sure to execute the operation referring to the procedures described in Section 6.21.2.

Absolute position data
Set the validity/invalidity of
restoring the absolute position.
0: Invalid
1: Valid
When 1 is set, the absolute
position is restored at system
startup, based on the home
position multiple revolution data
and the home position within 1
revolution position.
When 0 is set, the position at
system startup is defined to be 0.
Perform the home position return
prior to automatic operation and
linear interpolation.
Change of absolute position data
on home position reset
Set the validity/invalidity of
restoring the absolute position.
0: Invalid
1: Valid
When 1 is set, the absolute
position is restored at system
startup, based on the home
position multiple revolution data
and the home position within 1
revolution position.
When 0 is set, the position at
system startup is defined to be 0.
Perform the home position return
prior to automatic operation and
