[Setting of linear scale with distance-coded reference marks (serial)]
Follow the procedure below to measure the distance.
<1> Set parameters OPT (No.1815#1), DCL(No.1815#2), and
SDC(No.1818#3) to enable this function.
Set an appropriate value in parameters No. 1821 and No. 1882.
Set 0 in parameter No. 1240.
Set 0 in parameters No. 1883 and No. 1884.
<2> At an appropriate position, establish a reference position.
(As a result, the machine coordinate represents the distance from
the scale zero point to the current position.)
<3> By jog feed or handle feed, place the machine at the accurate
reference position.
<4> In parameter No. 1883 and No. 1884, set the machine coordinate
of that time converted to the detection unit (machine coordinate ×
CMR).
<5> If necessary, set parameter No. 1240.
NOTE
1 Set the valid range, within –999,9999,999,999 to
+999,9999,999,999 for setting parameter No.1883,
1884.If setting value is over the valid range, the
alarm PS5325 occurs.
2 It is not available to cross the scale zero under
scale valid area of the linear scale with
distance-coded reference marks (serial).Please
adjust the scale valid area which the scale zero is
located within the next scale zero is valid.

Allowable move amount of FL feedrate on establishment of reference
point(linear scale with distance-coded reference marks (serial))
[Input type] Parameter input
[Data type] 2-word axis
[Unit of data] Detection unit
[Valid data range] -999999999 to 999999999
On the linear scale with distance-coded reference marks (serial ), the
amount of movement on FL-speed during establishment of reference
point is set.
If the reference point is not established despite the amount of
FL-speed movement exceeds this parameter, alarm DS0017(SERIAL
DCL:REF-POS ESTABLISH ERR) occurs.
When this parameter is set to '0', the setting of allowable move amount
of FL feedrate on establishment of reference point (linear scale with
distance-coded reference marks (serial)) is ineffective.
