8.7.2 Changing the controller settings
The PI controller of the frequency inverter is optimised when leaving the factory,
therefore no changes are required.
Should a process-related adjustment of the PI controller be necessary, check/change
the factory settings in accordance with the following table:
Table 18: Main parameters of the PI controller:
Parameter Description Factory Set 1/
Factory Set 2 Setting range/options Access Reference to
3-9-1-1 Enable/disable PI controller 1 / 1 See selection list Customer
