Entering the PID Feedback Value
You can use two methods to input the PID feedback value to the drive. One method uses a single feedback signal
for usual PID control. The other method uses two signals. The difference between those signals sets the deviation.
• Use one feedback signal.
Use Table 11.30 to select how the feedback signal is input to the drive for PID control.
PID Feedback Input Method
Multi-function analog input terminal A1
Multi-function analog input terminal A2
Multi-function analog input terminal A3
Pulse train input terminal RP
• The drive uses two feedback signals, and the difference between those signals becomes the deviation.
Use Table 11.31 to select how the second feedback signal is input to the drive. The drive calculates the deviation
of the second feedback value. Set H3-02, H3-06, or H3-10 = 16 [Terminal A1/A3/A2 Function Selection =
Differential PID Feedback] to enable the second feedback signal used to calculated the deviation.
PID Differential Feedback Input Method
Multi-function analog input terminal A1
Multi-function analog input terminal A2
Multi-function analog input terminal A3
Note:
If you set more than one of H3-02, H3-06, and H3-10 to 16, it will trigger oPE07 [Analog Input Selection Error].
