Set the distance from the first grid point after leaving the near point dog on the slave axis to the position where
the reference position is actually established in dog-type reference position return in synchronous control.
(Reference position shift amount is not included.)
The adjustment value will be automatically set in the slave axis's parameter according to the reference posi-
tion adjustment complete signal from PLC.
Fine adjustment is also available from the parameter screen.
In the distance-coded reference position detection, the reference position adjustment value will be invalid.
(Note 1) This parameter is enabled when the synchronization at zero point initialization ("#1493 ref_syn" =
"1" of the master axis) is applied.
(Note 2) This parameter can be set when one of the following settings is applied.
- Relative position detection ("#2049 type" = "0")
- Dog-type absolute position detection ("#2049 type" = "3")
- Simple absolute position ("#2049 type" = "9")
(Note 3) Set "0" when using the speed/current command synchronization control.
(Note 4) A setting unit of this parameter is [mm]. It is not influenced by the content of the following parameters
setting.
- "#1003 iunit"
- "#1004 ctrl_unit"
- "#1005 plcunit"
- "#1040 M_inch"
- "#1041 I_inch"
- "#1240 set12/bit2" (Zero point shift amount magnification)
(Note 5) The number of the significant digits after decimal point follows "#1004 ctrl_unit"
(Note 6) A change of this parameter requires reference position return. When the automatic operation starts
without reference position return, an alarm will occur.
