Chapter 4 Key Characteristics of Actuator Control Commands and Points to

Note

1. Continuous Movement Commands

[PATH, CIR, ARC, PSPL, CIR2, ARC2, ARCD, ARCC]

[1] By running a program with continuous movement commands input in a series of continuous

program steps, you can allow the actuators to perform operations continuously without stopping
between steps.

PATH

12




[2] Continuous operation is possible even when all positions are not continuous.

Specify the position number of the discontinuous position for both the start position number and
end position number in the PATH command. In this example, position No. 6 is a skip point.

The actuator moves continuously in the sequence of position Nos. 1

 2  3  4  6  9 

10.

[3] Continuous movement will not be achieved if an input condition is specified for any continuous

movement command.

[4] The output field of each command will turn ON as the end position of that command approaches.

Only with the last command in a series of continuous movement commands, the output will turn
ON upon completion of operation (if there is no input condition).
