4.2.3 Setting of Distance-coded Reference Scale
(1) Setting of the base specifications
In order to set the distance-coded reference scale, the following setting follows "Setting of Machine Side Encoder".
【#2281(PR)】 SV081 SPEC2 Servo specification 2
bit 7 : szchk Distance-coded reference scale reference mark
Set the number of reference marks to be passed during the reference position calculation. If an error
occurs in passing the reference mark, the neighboring mark is checked. When an error is detected
three times in total, the alarm "42" will occur.
0: Check at 4 points (standard) 1: Check at 3 points
bit 3 : absc Distance-coded reference scale
0: Disable 1: Enable
【#2330(PR)】 SV130 RPITS Base reference mark interval
Set the interval between the base reference marks arranged at regular intervals on the distance-
coded reference scale. When the base reference mark interval (SV130) and the reference mark's
auxiliary interval are in the specified relationship, the distance-coded reference scale is judged to be
connected.
Following is the specified relationship.
(SV130×1000) / SV131 >= 4 (No remainder)
---Setting range---
0 to 32767 (mm)
【#2331(PR)】 SV131 DPITS Auxiliary reference mark interval
Set the auxiliary interval of reference mark in the distance-coded reference scale.
---Setting range---
0 to 32767 (μm)
