User Manual of EM730 Series Inverter F09.37=0: always calculate the integral term This function code does not affect the integral action. F09.37=1: calculate the integral term after the F09.21 set time is reached The integral is unavailable within the first change period (F09.21) after startup. F09.37=2: calculate the integral term when the error is less than F09.38 integral will be enabled again if the error is less than F09.38 within this period. The integral is unavailable within the first change period (F09.21) after startup. However, the F09.39=0: target pressure F09.01* coefficient of wake-up action point F09.40* preset F09.39=1:
wake-up action point (F09.30) The PID will wake up if the value is less than the wake-up point (F09.30) and kept for the wake-up delay time (F09.31). It is dedicated to the water pump application macro. When the overpressure of the pipeline network reaches the value of F09.41 and kept for the set time (F09.42), the E57 pipeline network overpressure protection will be reported. 250 within the set change time of PID Function code Function code name Parameter description Unit Default setting Attribute Mailing address F09.39 Wake-up option 0: target pressure F09.01* coefficient of wake-up action point 1:
