0: No function
1: Negative PID feedback: by analog input (Pr.03-00, 03-01)
2: Negative PID feedback: by single-phase input (MI7), without direction
(Pr.10-16 = 5)
4: Positive PID feedback: by analog input (Pr.03-00, 03-01)
5: Positive PID feedback: by single-phase input (MI7), without direction
(Pr.10-16 = 5)
7: Negative PID feedback: by communication protocols
8: Positive PID feedback: by communication protocols
 Negative feedback:
Error = + Target value (set point) – Feedback. Use negative feedback when the detection value
increases if the output frequency increases.
 Positive feedback:
Error = - Target value (set point) + Feedback. Use positive feedback when the detection value
decreases if the output frequency increases.
 When Pr.08-00 ≠ 7 or ≠ 8, the input value is disabled. The setting value does not remain when
the drive is powered 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)
