08 High-function PID Parameters

Terminal Selection of PID Feedback

08-00
Settings 0: No function
 Pr.08-00 ≠ 0 enables the PID function.
 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.
 When Pr.08-00 ≠ 0, the related applicable parameters include:
 Pr.00-20 (Master frequency command source (AUTO) / Source selection of the PID target)
 Pr.03-00–03-02:
When Pr.00-20 = 2 (External analog input), set Pr.03-00–03-02 = 4 (PID target value)
When Pr.08-00 = 1 or 4, set Pr.03-00–03-02 = 5 (PID feedback signal)
Refer to the following description for details.
1: Negative PID feedback: by analog input (Pr.03-00–03-02)
2: Negative PID feedback: by PG card pulse input, without direction
(Pr.10-02)
3: Negative PID feedback:by PG card pulse input, with direction (Pr.10-02)
4: Positive PID feedback: by analog input (Pr.03-00–03-02)
5: Positive PID feedback: by PG card pulse input, without direction
(Pr.10-02)
6: Positive PID feedback: by PG card pulse input, with direction (Pr.10-02)
7: Negative PID feedback: by communication protocols
8: Positive PID feedback: by communication protocols
