2) Types of PID control interfaces
Process quantity input data (frequency) and feedback input data can be combined as follows for the PID
control of the VF-S11:
Process quantity input data (frequency setting)

4) Adjusting the PID control gain level
Adjust the PID control gain level according to the process quantities, the feedback signals and the object to
be controlled.
The following parameters are provided for gain adjustment:
