Technical Questions and solutions
1. How to achieve Automatic start after stop?
If it is controlled by keyboard no need to set any parameter. If
you want to control by external switch
As the default control mode is keypad control, First set P00.06=1
and use a wire or switch to connect com and DI1,When the switch is
closed, the drive run, when the switch is open, the drive stop
2. How to use a float in the water tank to stop the pump if the tank
is full?
If your float signal is digital signal Use float switch to short DI
1 and com and P00.06=1
3.Use level probe in the well for protection against dry running?
Set P24.13=30%-40% and P24.14 P24.16 and P23.21
If your float signal is Analog signal, Connect Ai2 and 10V and GND
and set P41.00=23 and
P41.03-P41.06
Accessories:
1. GPRS (support 2g/3g/4g internet)
2. LCD keypad

Package:
When power is less than 45kw, we use carton package:
When power is more than 45kw, we use wood case package:
For 220V single phase motor connection
1: Single phase asynchronous motor wiring method (without starting
capacitor):
Notice: U is connected to the common end of the starting winding
and the working winding, V is connected to the starting winding,
and W is connected to the working winding;
Single-phase asynchronous motor if the rotary steering is not
correct, you can change the V and W wiring or set P22.13=1.
First solution: Set parameter P11.01=1 (Single phase motor type without capacitor) or second solution: set P00.11=31 if your motor frequency is 50
hz or set P00.11=32 if your motor frequency is 60HZ
For 220V single phase motor connection
2:Single-phase asynchronous motor wiring method (with capacitor)
Notice1:First solution: Connect motor cable to power terminal U and V and enter BSC mode to
Set parameter P23.15=0(output phase loss shielding protection) or second solution: set macro P00.11=21 if your motor frequency is
50HZ or set P00.11=22 if your motor frequency is 60HZ
