Ⅱ-1-2 Parameter setting
(1)Check the wiring to ensure the accuracy of wiring;
(2)Set the starting pump number E8.15 (according to the connection M1 named A motor, M2
named B motor, M3 named C motor, M4 named D motor), according to the field requirement to
start the motor needed first. If M2 motor starts first, set E8.15=2.
(3) Set up according to the actual situationE8.24 to E8.27;
(4)Single motor confirms that the direction of motor steering is the same, and the direction of
frequency inverter control rotation is the same as power frequency rotation. For example, starting
the inverter to observe the direction of rotation is the direction of pumping, and then starting the
power frequency to observe the direction of rotation is the direction of pumping. If the direction of
rotation of the frequency inverter mode is incorrect, arbitrarily switch two phases of KM1; if the
direction of rotation of the power frequency mode is incorrect, arbitrarily switch two phases of
KM2.
(5)Pressure gauge range (E8.04), dormancy and wake-up frequency, increase pump pressure,
decrease pump pressure, low-pressure and high-pressure alarm, time and pressure setting of multi-
stage pressure water supply, selection of motor rotation according to the actual situation. Please see
E8 functional parameters for details.
