6. Path
Operation
Description
Move continuously through four arbitrary points without stopping
(PATH movement).
The actuator moves along the path shown at right, without
stopping at P2 and P3.
Compared with MOVP and MOVL, this command does not
require the actuator to position exactly at P2 and P3, and thus
the movement tact time can be reduced.
Assume the following command is executed when the actuator
is stopped at P1:
PATH 2 4
The actuator will move from P1 to P4 by passing points near P2
and P3. (The passing points can be brought closer to the
specified positions by increasing the acceleration.)
Even if “PATH 2 3” and “PATH 3 4” are input successively, the
actuator will still move in the same way as when “PATH 2 4” is
input.
If “PATH 4 1” is executed while the actuator is stopped at P4,
the actuator will move along the same path in the opposite
direction (P4
P3 P2 P1).
Continuous operation is possible even when all positions are
not continuous.

As shown above, specify the position number of the
discontinuous position, or No. 6 in this case, for both the start
position number and end position number in the PATH
command. The actuator will move continuously in the sequence
of position Nos. P1
P2 P3 P4 P6 P9 P10.
