APC APZ OPT
Axis type
OPT 0 : Position detection is performed by the pulse coder built in the
motor.
1 :Separate type pulse coder or linear scale is used.
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.
APC 0 : Position detector is other than absolute pulse coder.
1 :Position detector is absolute pulse coder.

Reference counter size for each axis
Axis type
Set the size of the reference counter.
To set the size of the reference counter, specify the grid interval
for the reference position return in the grid method.
Size of the reference counter =
grid interval
detection unit
Grid interval = the amount of travel per rotation of the pulse coder
1836
Servo error amount where reference position return is possible
Axis type
This parameter sets the servo error used to enable reference
position return in manual reference position return.
In general, set this parameter to 0. (When 0 is set, 128 is
assumed as the default.)
1850
Grid shift for each axis, shift of reference position
Axis type
A grid shift is set for each axis.
To shift the reference position, the grid can be shifted by the
amount set in this parameter. Up to the maximum value counted
by the reference counter can be specified as the grid shift.
When PRM1002#2(SFD) is set to 1, this parameter specifies a
reference position shift amount.

DEC
DEC Deceleration signal (*DEC1 to *DEC8) for manual reference
position return
0 : Deceleration is applied when the signal is 0.
1 : Deceleration is applied when the signal is 1.
