6.11Performing PI control

H : PI control

H : Proportional (P) gain

H : Integral (I) gain

• Function

These parameters are used to perform various kinds of process control, such as keeping the air quantity, flow rate or pressure constant by inputting feedback signals (4~20mA, 0~10V) from a detector.

[Parameter setting]

Feedback signal: 4~20mA, 0~10V

2) Types of PI control interfaces

The following combinations of process quantity data (frequency setting) and feedback data can be entered for PI control.

Process quantity input data (frequency setting)		Feedback input data
Setting mode	Frequency setting mode	External analog input
	HOQF	H: 0 (voltage input)
①Internal potentiometer setting		①VI/S3 (DC: 0~10V)
②Panel input setting		H:1 (current input)
③Preset speed setting	or	②VI/S3 (DC: 4~20mA)

Note: When the PI control function is enabled (H: 1), the VI/S3 terminal is used exclusively as a feedback signal input terminal.

Note: Do not set Frequency setting mode (HOQF) parameter to 0 if VI/S3 terminal is not used as contact input.

If all terminals for preset speed are off, a speed command other than the preset speed

3) Setting the PI control parameter

Set the extended parameter H (PI control) to (enabled).

(1)It is recommended to set the parameters CEE (acceleration time) and FGE (deceleration time) to as small values as possible.

(2)If there is a need to limit the output frequency, set it with the parameters WN (upper limit frequency) and NN (lower limit frequency). When process quantities are set from the operation panel, their adjustment ranges are limited by the settings of WN (upper limit frequency) and NN (lower limit frequency).
