This parameter is used to select the target volume of the process PID.
The set value of the process PID is the relative value, and the setting range is 0.0% ~
100.0%. The same PID feedback is the relative amount, the role of PID is to make the two
relative amount of the same.

This parameter is used to select the feedback channel of the process PID
。
The set value of the process PID is the relative value, and the setting range is 0.0% ~ 100.0%

Positive function: When the PID feedback signal is less than a given amount, the inverter
output frequency increases. Such as the tension of the tension control occasions.
