0: On the negative direction side. (Viewed from the scale zero point, the
reference position is on the positive direction side.)
1: On the positive direction side. (Viewed from the scale zero point, the
reference position is on the negative direction side.)

RFSx
[Data type] Bit axis type
RFSx On an axis using a linear scale with absolute addressing reference marks,
if an automatic reference position return (G28) is made before the
reference position is established, the
reference position is established first,
then:
0: A movement to the reference position is made.
1: A movement to the reference position is not made, but the operation is
completed.
RF2x On an axis using a linear scale with absolute addressing reference marks,
if an automatic reference position return (G28) is made after the reference
position is established,
0: A movement to the reference position is made.
1: A movement to the reference position is not made, but the operation is
completed.
DG0x On an axis using a linear scale with absolute addressing reference marks, a
reference position return by jog feed or a rapid traverse command is:
0: Disabled.
1: Enabled.

FUPx

[Data type] Bit axis
FUPx To perform follow–up when the servo is off is set for each axis.
0: The follow–up signal, *FLWU, determines whether follow–up is
performed or not.
When *FLWU is 0, follow–up is performed.
When *FLWU is 1, follow–up is not performed.
1: Follow–up is not performed.
NOTE
When the index table indexing function (M series) is used,
be sure to set FUPx of the 4th axis to 1.
CRFx When servo alarm No.445 (software disconnection), No.446 (hardware
disconnection), No.447 (hardware disconnection (separate type)), or
No.421 (excessive dual position feedback error) is issued:
0 : The reference position setting remains as is.
1 : The system enters the reference position undefined state.
DATx On a linear scale with absolute addressing reference marks, the automatic
setting of parameters No. 1883 and No. 1884 is:
0: Not performed.
1: Performed.
