
Positioning Data Type (d237)
Handling of the positioning data set to positioning data 1 to 8 can be switched between handling as
absolute positions or as moving amounts.
To switch handling when necessary, use increment/absolute position switching “INC/ABS” (data =
135) in the multifunction input terminal function.
When “INC/ABS” is allocated to multifunction input terminals, the d237 setting is disabled.

Position Data Determination T
ime (d238)
When position command selection 1 “CP1” to position command selection 3 “CP3” is switched,
chattering may cause the selected positioning data to change. In cases like these, set the time up
to settling of the positioning data to d238.

Positioning Data Setting Selection via communication (d277)
Positioning data can also be assigned via communication. To assign positioning data via communi-
cation, set 1 to d277. The upper four digits and lower four digits of the positioning data are as-
signed to Positioning Data via Communication (MSB) (S20) and Positioning Data via Communica-
tion (LSB) (S21), respectively.
To reflect positioning data, turn the position change command “POS-SET” ON.
While commands via communication are enabled, Positioning Data 1 (MSB) (d244) and Positioning
Data 1 (LSB) (d245) are switched to S20 and S21. These parameters can also be switched to posi-
tioning data 2 to 8 by position command selection 1 “CP1” to position command selection 3 “CP1.”
