Input Methods for the PID Setpoint
Pulse train input terminal DI
b5-19 [PID Setpoint Value]
Note:
If you set two inputs for the PID setpoint, it will trigger operation error oPE07 [Analog Input Selection Error].

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 12.11 to select how the feedback signal is input to the drive for PID control.
PID Feedback Input Method
Multi-function analog input terminal AI1
Multi-function analog input terminal AI2
Multi-function analog input terminal AI3
Pulse train input terminal DI
• The drive uses two feedback signals, and the difference between those signals becomes the deviation.
Use Table 12.12 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 = 11 [AI1 Function Selection, AI3
Function Selection, or AI2 Function Selection = Diff PIDFbk] to enable the second feedback signal used to
calculated the deviation.
PID Differential Feedback Input Method
Multi-function analog input terminal AI1
Multi-function analog input terminal AI2
Multi-function analog input terminal AI3
Note:
If you set more than one of H3-02, H3-06, and H3-10 to 11, it will trigger oPE07 [Analog Input Selection Error].
