The function is available for only FS16i/18i-MA/MB
When the function is applied for simple synchronous axis, the following condition
should be kept.
(1) Distance coded linear scale with the same reference marks at intervals should
be applied for the master axis and the slave axis.
(2) The master axis scale and the slave axis scale should be installed in parallel
direction. (The zero positions should be faced the same direction.)
(3) To the parameters, which relates to this function (except No.1883, No.1884),
the same value must be set for the master axis and for the slave axis.
(4) During operating the establishment of reference position, the state of
synchronous control selection signal (SYNCJn<G0140>) should be kept.
Procedure for Reference Position Establishment by synchronous axis is as follows.

- When either reference mark of the master axis or the slave axis is detected, the
both axes stop. And the both axes are fed again at a Reference Position Return
FL Feedrate.
- The above mentioned operations are repeated until the master axis and the slave
axis detect enough (3 or 4) reference marks.
- Absolute position of both axes are calculated and Reference Position
Establishment Signal (ZRF1,ZRF2,...) turns to "1".
