Terminal Selection of PID Feedback
Default: 0
Settings 0: No function
1: Negative PID feedback: by analog input (Pr.03-00)
2: Negative PID feedback: by single-
phase pulse input (MI7), without direction
(Pr.10-16)
3: Negati
ve PID feedback: by single -phase pulse input (MI7), with direction
(Pr.10-16)
4: Positive PID feedback: by analog input (Pr.03-00)
5: Pos
itive PID feedback: by single -phase pulse input (MI7), without
direction (Pr.10-16)
6: Pos
itive PID feedback: by single -phase pulse input (MI7), with direction
(Pr.10-16)
7: Negative PID feedback: by communication protocol
8: Positive PID feedback: by communication protocol
 Negative feedback means: Error = Target value - Feedback.
The detection value increases by increasing the output frequency.
 Positive feedback means: Error = Feedback - Target value.
The detection value decreases by increasing the output frequency.
 When Pr.08-00 ≠ 7 neither ≠ 8, the input value is disabled. The value of the setting does not
remain the same after the drive is off.
 The related applicable parameters to set Pr.08-00 include:
 Pr.00-20 (Master frequency command source (AUTO)
 Pr.03-00–03-01:
When Pr.00-20 = 2, set Pr.03-00–03-01 =4 (PID target value)
When Pr.08-00 = 1 or 4, set Pr.03-00–03-01 = 5 (PID feedback signal)
