(12)Positioning option configuration
The positioning option consists of "[Da.27] M code ON signal output timing" to "[Da.29] Interpolation speed
designation method". The set values of those data are stored in one buffer memory address. Consider the
positioning option configuration in the figure below when setting "[Da.27] M code ON signal output timing" to
"[Da.29] Interpolation speed designation method".

(13)[Da.27] M code ON signal output timing
Set the M code ON signal output timing for each positioning data.
(14)[Da.28] ABS direction in degrees
Set the ABS moving direction when "degree" is selected as the unit for each positioning data.
(15)[Da.29] Interpolation speed designation method
Set the interpolation speed designation method for each positioning data.
● To use the positioning option, set "1: Valid" in [Pr.70] Positioning option valid/invalid setting.
● The positioning option can be set only with GX Works2 (Version 1.540N or later) or programs.
● The positioning option can be set only for the LD75 with a serial number (first five digits) of "17102" or later. If a value is
set for the positioning option of the LD75 with a serial number (first five digits) earlier than "17102" and a positioning
control is started, the value set in the positioning option is ignored.
