Multistep Operation Using Continuous Paths (Fx 2N -10Gm) - Mitsubishi FX2N-10GM Hardware / Programming Manual

FX Series Positioning Controllers
5.4.3 Multistep operation using continuous paths (FX
Though the cod 01 (LIN) is a linear interpolation instruction, it can be used for multistep opera-
tion by specifying continuous paths in the FX
• Create a program accord-
ing to the operation exam-
ple shown below.
• The travel can be specified
by either the absolute drive
method (ABS) or the incre-
mental drive method (INC).
However, when the drive
method is changed during continuous paths, the machine stops temporarily.
Example of incremental drive
Ox 00,N0
N0 cod91(INC);
N1 cod01(LIN)
x1500
f3000;
N2 cod01(LIN)
x1000
f2000;
N3 cod01(LIN)
x2500
f1600;
N4 m02(END);
• In multistep operation, preparation for the next process is performed at the same time as the
present process. Accordingly, when the available distance for change-over from the present
operation speed to the next step speed is too small or when the travel time is short, the
machine may not continue operation but is stopped temporarily.
• The number of multi-steps (number of continuous paths) is not restricted at all. The opera-
tions using m codes are performed in the same way as described for continuous paths on
the previous page.
• In the FX

tion are possible because interpolation control is required. The unspecified axis does not
move.)
