When the resolution is 0.0001mm, set the value in the unit ten times
the detection unit.

#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.
#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.
#5(APC) 0 : Position detector is other than absolute pulse coder.
1 : Position detector is absolute pulse coder.
1821 Reference counter capacity per axis [P]
PRM
Normally, the number of feedback pulses per motor revolution is set to
the reference counter capacity.
When plural reference marks are on a linear scale, a quotient of the
distance between the reference marks divided by an interfer may be used
as a reference counter capacity:
Example)
(1µ m)
300mm⇒ reference counter 30000
20000
15000
10000 etc
