9. Set the reference counter capacity. (Parameter No. 180)
Set the reference counter capacity when performing a reference position return
operation based on the grid method. Set the number of position pulses per motor
revolution, or set that number divided by an integer.
Example: αi pulse coders, semi-closed loop (1um detection)

10. Turn off/on both CNC and servo amplifier unit and servo parameter initialization is
finished.
11. If you use αi pulse coder as an absolute pulse coder, some procedures described
below are needed.
1) Set the following parameter, then turn off / on the CNC and servo amplifier unit.

APCX (b7) Absolute position detector is
0 : not used 1 : used
ABSX (b0) Position of machine and position of absolute pulse coder
is
0 : not matched 1 : matched
2) Check the connection of the pulse coder battery, then turn off/on CNC and
servo amplifier unit.
3) CNC requires the reference position return.
4) Rotate the servo motor through one or more rotations by jogging and so on.
5) Turn off/on the CNC and servo amplifier unit.
6) CNC requires the reference position return again.
7) Perform reference position return. The ABSX is set to 1 after finishing the
reference position return.
