2 PID Group 9 parameter descriptions 09-00:
PID operation selection = 0: disable =1: enable (Deviation is D-controlled) =2: Feedback D-controlled =3: D Reverse characteristic controlled =4: Feedback D characteristic controlled =5: Frequency command + D controlled =6: Frequency command + Feedback D controlled =7: Frequency Command + D reverse Characteristic controlled. =8: Frequency Command + Feedback D reverse Characteristic controlled.
09-00 =1, D is the deviation of (target value –detected value) in the unit time (09-04). =2, D is the deviation of the detected values in unit time (09-04). =3, D is the deviation of (target value – detected value) in the unit time (09-04). If the deviation is positive, the output frequency decreases, vice versa. =4, D is the deviation of detected value in unit time (09-04). When the deviation is positive, the frequency decreases, vice versa. =5, D is equal to the deviation of (target value – detected value) in unit time (09-04) +Frequency command. =6, D is equal to the deviation of detected values in unit time + Frequency command. =7, D is equal to the deviation of (target value – detected value) in unit time +Frequency command. If the deviation is positive, the output frequency decreases, vice versa. =8, D is equal to the deviation of detected values in unit time + Frequency command. When the deviation is positive, the frequency decreases, vice versa. 09-01: Feedback Gain coefficient (%) 0.00 - 10.00 09-01 is the calibration gain. Deviation = set point –(feedback signal×09-01) 09-02: Proportional Gain(%) 09-02: Proportion gain for P control.
0.00 - 10.00
09-03: Integration Time (s) 0.0 - 100.0 09-03: Integrate time for I control 09-04: Differentiation Time (s) 0.00 - 10.00 09-04: Differential time for D control 09-05:
PID Offset
0 : Positive Direction
1 :Negative Direction 09-06: PID Offset Adjust (%) 0 ~ 109 09-05/09-06: Calculated PID output is offset by 09-06 (the polarity of offset is according to 09-05). 09-07: PID Output Lag Filter Time (s) 0.0 - 2.5 09-07: Update time for output frequency. 4-48
