Note:
Our switch is actually a self-holding type.
Potentiometer usage method:
An external potentiometer can be used.
External potentiometer connection method:
5VIN connects to the potentiometer's middle pin,
5Vout and GND connect to the other two pins of the potentiometer.
Parameters:
PN03=3
Potentiometer resistance: 500 ohms to 10k ohms.
The maximum output frequency of the potentiometer is the frequency set by the PN10 parameter.

Hardware connection description:
Connect FWD and GND for forward rotation; disconnect to stop.
Connect REV and GND for reverse rotation; disconnect to stop.
Connect both FWD and REV to GND for reverse rotation; disconnect all to stop.
Connect both wires from your controller's switch to FWD and GND.
The controller switch must be a contact-type switch only.
Do not supply any voltage to the controller, as this will permanently damage the inverter.
The inverter has an internal self-powered circuit.

After setting the above parameters:
Press RUN on the panel to start, STOP to stop.
Press FWD/REV to switch between forward and reverse rotation.
Use the up/down keys on the panel to adjust speed.
Detailed menu operation instructions are on page 8 of the manual.
Page 36 of the manual contains detailed application instructions.
Simply follow our settings above for guaranteed first-time success.
External start application method:
pn04=2 (monitor pn07 parameter)

To modify your motor for three-phase 220V wiring:
Rewire the motor terminal box internally to a delta configuration.
Below are test parameters:
pn32=6
pn02=Motor rated frequency
pn03=2
pn04=1
pn10=Motor rated frequency
pn12=Motor rated frequency
By vevor
Derating is only required when used with air compressors; it's unnecessary for other applications. Please provide detailed information about your specific use case.
Testing method provided below:
Power connection method:
For single-phase 220V, connect to R and T terminals. Leave S terminal unconnected.
For three-phase 220V, connect to RST.
Connect the motor's three wires to U, V, W.
Only wire connections are permitted between the motor and inverter; no intermediate switches may be installed.
