External Interruption

If an external interruption is encountered, it uses the PR Command trigger method to execute
another PR path (refer to Section 7.1.5 for PR trigger methods). When the PR queue receives a
PR path with an Interrupt function, it sends this path to the motion command generator
immediately and changes the path in execution. Note that a delay does not change the result of
an external interruption. That is, once the PR queue receives an external interruption command,
the motion commands in the latter part are executed by the generator and integrated with the
previous commands. The external interruption is as shown in Figure 7.1.6.10 (a).
If a PR path with external interruption enters the PR executor, the executor sends this Position
command immediately to the generator so that the motor can run in accordance with the
interruption. The motor uses the settings that integrate with the former motion commands when
running. The methods of integration are described in Section 7.1.3. Similarly, an external
interruption affects Speed and Position commands the same way and the same is true for
multiple commands. See Figure 7.1.6.10(b) for an example.
