#1(DLZ) 0 : The normal method (dog) is used for reference position return.
1 : Reference position setting without dogs is used (axis by axis).
NOTE
A reference position can be set axis by axis by setting bit 1
of parameter No. 1002 to 0 and setting bit 1 of parameter
No. 1005. Reference position setting without dogs cannot
be used for a spindle positioning axis and Cs contour axis.
When these axes are involved, use bit 1 of parameter No.
1005.
1821 Reference counter capacity [P]
PRM
No. of feedback pulses or its division by an integer is set.
1850 Grid shift amount per axis [P]
PRM
When the resolution is 0.0001mm, set the value in the unit ten times
the detection unit.

PRM
#5(APC) 0 : Position detector is other than absolute pulse coder.
1 : Position detector is absolute pulse coder.
#4(APZ) Zero position of absolute pulse coder is
:
0 : Not established
1 : Established
(Turns to 1 after establishment)
To manually change the value of the APZ bit from 0 to 1 without first
returning to the reference position
when using serial pulse coder α , follow this procedure: Back up the
data with the battery and give the motor one or more turns.
Turn the power off then on again, then change the APZ bit setting
from 0 to 1.
#1(OPT) 0 : Position detection is performed by the pulse coder built in the motor.
1 : Separate type pulse coder or linear scale is used.
