1) Outline of positioning
When positioning is completed, the positioning unit transfers the m code signal to the FX
2N
Series PLC, and the PLC performs an auxiliary unit operation corresponding to the m code.
2) Operating procedure
c
When the start command (X000) is input, the machine returns to the zero point only at
the first time, and regards that position as the electrical zero point.
d
When the machine stops at the first point (A), the positioning unit transfers the m10 code
to the PLC. When receiving the M10 code, the PLC makes the auxiliary unit No. 1 (Y010)
operate. When operation of the auxiliary unit No. 1 is finished, the PLC turns off Y010,
and transfers the m code OFF command to the positioning unit.
e
When receiving the m code OFF command, the positioning unit turns off the m code, and
the machine moves to the second point (B). When the machine reaches the point B, the
positioning unit transfers the m11 code to the PLC. When receiving the m11 code, the
PLC makes the auxiliary unit No. 2 (Y011) operate. When operation of the auxiliary unit
No. 2 is finished, the PLC turns off Y011 and transfers the m code OFF command to the
positioning unit.
f
When receiving the m code OFF command, the positioning unit turns off the m code, and
the machine moves to the electrical zero point. Now, operation is finished.
