12.3 b: Application
• Use Single Feedback Signal
Use Table 12.26 to select how the feedback signal is input to the drive for PID control.
PID Feedback Input Method
MFAI terminal A1
MFAI terminal A2
MFAI terminal A3
Pulse train input terminal RP
• Use Two Feedback Signals and Calculate the Deviation from the Difference between Those Signals
Use Table 12.27 to select how the second feedback value 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
MFAI terminal A1
MFAI terminal A2
MFAI terminal A3
Note:
If you set two or more of H3-02, H3-06, and H3-10 to 16, it will trigger oPE07 [Analog Input Selection Error].
