User Manual of EM760 High-Performance 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 The integral is unavailable within the first change period (F09.21) after startup. However, the integral will be enabled again if the error is less than F09.38 within this period. F09.39=0:
target pressure F09.01* coefficient of wake-up action point The PID will wake up if the PID feedback is less than F09.40 * pre-setting and such state lasts for the F09.31 wake-up delay time. F09.39=1: wake-up action point (F09.30) The PID will wake up ifthe PID feedback is less than F09.30 and such state lasts for the F09.31 wake-up delay time. 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. It is dedicated to the straight wire drawing machine of the winding and unwinding application micro.
When F27.00 is set to the option 3 (straight wire drawing machine) and the feedback signal is the maximum value for a long time after startup, the system will be adjusted by PID to the negative output. F09.43=0 : No limit When the output is reduced to 0, it will not be limited and may continue to decrease. F09.43=1: limit When the output is reduced to 0, it will be limited and not continue to decrease. 97 Function code Function codename Parameter description Unit Default setting Attribute F09.39 Wake-up option 0: target pressure F09.01* coefficient ofwake- up action point 1:
