WARNING
If you set parameter 1818#3 (SDCx), please don’t forget to
turned off before operation is continued. This parameter
doesn’t generate P/S alarm 0 (Power–off alarm).

DATx When manual reference point return is executed, the automatic setting of
paramete 1883,1884 is:
0 : Not executed.
1 : Executed.
The procedure of the automatic setting are following :
(1)Set a correct value to parameter No.1815,1821,1882.
* On the linear scale with distance–coded reference marks (serial),
parameter No.1882 is unnecessary to set.
(2)Positioning the axis to reference position by mechanical measurement
by manual operation.
(3)Execute manual reference point return.
When the manual reference point return is finished, parameter
No.1883,1884 are set and No.1819#2 is turn to ’0’.
1821 Reference counter size for each axis
[Data type] 2–word axis
[Unit of data] Detection unit
[Valid data range] 0 to 99999999
Sets the intervals of mark 1 of the linear scale with abssolute addressing
referenced marks.
CAUTION
On the linear scale with distance–coded reference marks
(A/B phase), this parameter is used on the usual purpose.
(Setting reference counter size foreach axis)
1882
Space between mark–2 indications on the linear scale with absolute
addressing reference marks
[Data type] 2–word axis
[Unit of data] Detection unit
[Valid data range] 0 to 99999999
Sets the intervals of mark 1 of the linear scale with abssolute addressing
referenced marks.
