PID Diagram for PID parameter adjustment
*
PID parameters can be modified during the inverter is running.
14-09 Tolerance Range of Constant Pressure
Range
When 14-20=0, range is 0.00~650.00
When 14-20=1, range is 0~100
When pressure feedback value is in the range of 14-02+14-09, inverter output frequency will
decrease downward into sleep status.
14-10 Sleep Frequency of Constant Pressure
Range
【0.00~599.00】Hz
When inverter output frequency falls below 14-10 (sleep frequency of constant pressure), it
starts to count the sleep time (14-11).
14-11 Sleep Time of Constant Pressure
Range
【0.00~255.5】s
When the inverter finishes counting the sleep time (14-11), the output frequency falls
downward at the deceleration time (00-15) and gets into sleep status. Parameter 14-10 (sleep
frequency of constant pressure) is dedicated by the pump and it is not applied to parameter 10-17
(start frequency of PID sleep).
