Linear Interpolation (Fx 2N -20Gm) - Mitsubishi FX2N-10GM Hardware / Programming Manual

FX Series Positioning Controllers
9.4.2 Linear interpolation (FX
1) Outline of positioning
The machine moves to the target address in a linear route, waits until an auxiliary unit fin-
ishes its work, then returns to the zero point.
2) Operating procedure
cThe machine returns to the zero point by the start command only at the first time.
dThe machine moves to the target address in a linear route.
eThe output Y0 turns on and off.
fThe machine returns to the zero point (0, 0).
