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(%) 0.00 - 10.00
09-02: Proportion gain for P control.
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.
