7.5 High speed monitor function
7.5.1 Summary
High speed monitor function is a function for monitoring current command position and current feedback
position etc. It becomes valid after system is started up, and monitor data is updated every control cycle.
The data that can be referenced with the high speed monitor function are the following 6 items.
