This VFD can be used for constant torque loads ( such as hard starting: Air compressors, HVAC units) and variable torque loads (such as pumps, fans, etc). It can be used as a motor speed control and a phase converter. The input for this VFD is 1 phase . You can control the different speed as you like when yo use this VFD. Many customer bought this VFD from us to use for: Lathes, Mills, Car Hoists, Pumps & Conveyors, etc and then performance excellently. This item use Sine wave PWN(SPWM ) for the control system and performance excellently.
About the item:
【Connection way】Input:220VAC(+/-5%) 1 or
3phase(for single-phase input, just connect the input wire to the R and S
terminals) Output:3phase 220v. Frequency:0-50hz/60hz. 0-400hz
【Multiplex
terminal】Unlike other inexpensive VFDS, this VFD has two sets of
terminal functions,Rich of digital and analogy control terminals for
versitile control,optional MODBUS (RS485) extension,diversified
parameter setting
【Safety performance】Take advantage of various
protection ways such as Motor short-circuit detection at power-on,
output phase loss protection, over-current protection, over-voltage
protection, under-voltage protection, overheat protection, overload
protection and etc.
【Good Noise Control】The product has the
advantages of low noise and low electromagnetic interference, which are
achieved by the excellent PMW control technology and component
compatibility design. There is enough space for cooling between each
component, and the product casing is designed with multiple holes, the
above features can make this VFD have a longer service life.
【Warranty】:
Lifetime warranty .If there is an error code in the product and you do
not know how to operate, please contact the seller.

Test parameters and methods:
1. Power connection mode,
If you use single-phase 220v, please connect to R and T, S is empty and do not need to be connected.
If you are three-phase 220v then connect to RST.
The three lines of the motor are connected to U,V and W.
2.Test Parameters
pn32=3
pn02= rated frequency of motor
pn03=2
pn04=1
pn10= rated frequency of motor
pn12= rated frequency of motor
After the above Settings,
Press panel RUN to start and panel STOP to stop.
Press fwd/rev to switch forward and backward
Press the up and down buttons on the panel to adjust the speed
There are detailed menu instructions on page 8 of the manual
Note:The motor and frequency converter can only be connected by wire, and the switch cannot be installed in the middle
