Set one of the above values when using PID control.
The following table shows how to determine the target value and the
feedback value to be input when the PID control is enabled.

The frequency reference
that is set to the PID
feedback value selection
(n164)
Condition
Determined by the frequency reference selection
(n004).
When the local mode is selected, the target value is
determined by frequency reference selection in local
mode (n008).
When the multi-step speed reference is selected,
the currently selected frequency reference becomes
the target value.
