Note 1. Normally select feedback-value integral PID control as the derivative control method.
Note 2. Add the frequency reference if the target of control is motor speed and do not add the fre-
quency reference if the target of control is temperature or pressure.
Note 3. Set positive or negative characteristics according to the characteristics of the detector. If the
feedback value is decreased with the output frequency increased, set negative characteris-
tics.
Note 4.
Set PID control in n128 (PID Control Selection) only after returning n077 to 0. An error will occur and it
will not be possible to change n128 if n077 is set to other than 0 (disable).

Set Values
Set the multiplication rate of the feedback value.
This parameter adjusts the feedback value so that the input level of the input device, such as a sensor,
will coincide with the input level of the target value.
For example, if the target value of 1,000 rpm is input as 10 V and the feedback value at 1,000 rpm is
5 V, the feedback value will be doubled.
