12.2 b: APPLICATION
Use Table 12.14 to select how the feedback signal is input to the drive for PID control.
PID Feedback Input Method
MFAI terminal AI1
MFAI terminal AI2
Pulse train input terminal DI
• Use two signals, and use the difference between those signals as the feedback signal.
The drive uses two feedback signals, and the difference between those signals becomes the deviation.
Use Table 12.15 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 or H3-10 = 11 [AI1 Function Selection or AI2 Function Selection =
Diff PIDFbk] to enable the second feedback signal used to calculated the deviation.
PID Differential Feedback Input Method
MFAI terminal AI1
MFAI terminal AI2
Note:
If you set H3-02 and H3-10 = 11, it will trigger oPE07 [Analog Input Selection Error].

PID Feedback Loss Detection
The PID feedback loss detection function detects broken sensors and defective wiring between the drive and
sensors.
