3 Reserved
Select an input terminal to serve as the PID feedback location. When Pr.07-06 is set to 0 or 2,
Pr.07-05 can’t be set to 1.
Negative feedback = Positive target value – detection value. It is used for the application that
the detection value will be increased by increasing output frequency.
Positive feedback = Negative target value + detection value. It is used for the application that
the detection value will be decreased by increasing output frequency.
07-07 Proportional Gain (P) Unit: 0.1
Settings 0.0 to 10.0 Factory Setting: 0.2
This parameter is used to determinate error gain. If I = 0 and D = 0, doing proportional gain
operation.
