 How to optimise the system:

1. Use the menu command Online  Login, or log in on the Lenze controller with <Alt>+<F8>.

With the log-in, the I/O device configuration is loaded into the controller.

2. Check the task processing times.

3. Optimising the cycle times:

• If technologically required, the cycle times of the remaining tasks with lower priorities

can be decreased.

• Condition: No task with a low priority must assign more than 60 percent of the

corresponding cycle time in its task utilisation.
