3.5 Sample/update times
The samples/update times shown in the control terminal specification within the Commander SK Product Data Guide are the default sample/update
times for the default terminal set-up. The sample/update time depends on the destination/source parameter of the digital or analog inputs/outputs.
These sample/update times are the sample or update times for the control microprocessor. The actual sample/update time maybe slightly longer due
to the design of the Commander SK.
3.5.1 Task routine times
At the beginning of each menu, there is a single line parameter description and this contains the update rate for each parameter. This time signifies
the task routine time in the software that the parameter is updated on. For a background task, the time depends on processor loading i.e. what
functions the drive is carrying out and what advanced menus are being used.
From practical tests carried out:
