Note
•
Normal PID output (PID OUT) is bipolar and is limited by PID-46 (PID Limit Hi) and PID-47 (PID
Limit Lo) settings. DRV-20 (MaxFreq) value equals a 100% of PID OUT.
•
The following are the variables used in PID operation, and how they are calculated:
- Unit MAX = PID Unit 100% (PID-68)
- Unit Min = (2xPID Unit 0% (PID-67)–PID Unit 100%)
- Unit Default = (PID Unit 100%-PID Unit 0%)/2
- Unit Band = Unit 100%-Unit 0%
•
PID control may be utilized for the following operations:
Soft fill, auxiliary PID reference compensation, MMC, flow compensation, pipe breakage
detection
•
During a PID operation, the PID output becomes the frequency reference. The inverter
accelerates or decelerates to the frequency reference based on the Acc/Dec times.
PID Basic Operation Setting Details
Code Description
PID-01 PID Sel Sets the code to ‘1 (Yes)’ to select functions for the process PID.
PID-03 PID Output
Displays the existing output value of the PID controller. The unit, gain, and
scale that were set in the PID group are applied on the display.
PID-04 PID Ref Value
Displays the existing reference value set for the PID controller. The unit, gain,
and scale that were set in the PID group are applied on the display.
PID-05 PID Fdb Value
Displays the latest feedback value of the PID controller. The unit, gain, and
scale that were set in the PID group are applied on the display.
PID-06 PID Err Value
Displays the differences between the existing reference and the feedback
(error value). The unit, gain, and scale that were set in the PID group are
applied on the display.
PID-10 PID Ref 1 Src
Selects the reference input for the PID control. If the V1 terminal is set to a PID
feedback source (PID F/B Source), the V1 terminal cannot be set to the PID
reference source (PID Ref Source). To set V1 as a reference source, change the
