Positioning By Constant Quantity Of Reciprocating Motion (Fx 2N -10Gm, Fx 2N -20Gm) - Mitsubishi FX2N-10GM Hardware / Programming Manual

FX Series Positioning Controllers
9.3.2 Positioning by constant quantity of reciprocating motion (FX
1) Outline of positioning
The machine moves a workpiece from the left table to the right table.
A single solenoid is used to move up and down the workpiece.
2) Operating procedure
c The machine returns to the zero point by the start
command only at the first time.
d The move-down solenoid Y0 turns on. When the
lower limit X0 turns on, the clamp solenoid Y1
turns on and the machine clamps a workpiece.
e After the clamp wait period of time (1.5 seconds),
the move-down solenoid Y0 turns off and the
machine moves up.
f When the upper limit X1 turns on, the machine
moves to the right table.
g When the machine reaches the right table, the move-down solenoid Y0 turns on. When
the lower limit X0 turns on, the clamp solenoid Y1 turns off and the machine unclamps (=
releases) the workpiece.
h After the unclamp wait period of time (1.5 seconds), the move-down solenoid Y0 turns off
and the machine moves up.
i When the upper limit X1 turns on, the machine returns to the left table.
