Terminal Selection of PID Feedback

Default: 0

Settings

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)
