![]() ![]() I cannot find a fuse anywhere in the box. The manual also says that the VFD is fuse protected. So, does anyone have a circuit diagram for this inverter, or better still can anyone advise me what component has failed? (The motor is not connected)Ģ) Check whether the insulation of the output wires is good. Their suggested course of action for this fault is:ġ) Check whether the connection wire of the motor has a short circuit. Measurements across the V-W terminals was 8.5v, Then after pressing start it was 8.3 then after pressing stop it was 10.6vĪs soon as I press the start button I get a fault dL which according to the manual is an output short circuit. Measurements across the U-W terminals was 4.3v, Then after pressing start it was 4.0 then after pressing stop it was 2.6v Measurements across the U-V terminals was 10.6v, Then after pressing start it was 11.1 then after pressing stop it was 10v It measures very high resistance between all terminals: The thing that is wrong with it seems to be nothing at all on the output side. The first thing you will need is the dynamic link library to pair with mach3 called the Huanyang VFD Mach3 PlugIn. It is possible to connect and configure the spindle VFD to the mach3 via an RS485 communication and protocol. After many days of measuring and them assuring me that it was a minor problem that they could fix easily, they finally said that they couldn't fix it and that they would send me a new inverter (I have to pay another $35 freight. Question: How to configure 2.2KW VFD for Modbus communication with Mach3. I could not get it to work, and told the supplier in China that it was a dud. ![]() I recently bought a Huanyang HY03D023B inverter, which is a 220v input 3.0 KW output VFD. I obviously haven't read all the posts in this section but wonder if anyone can help me? ![]()
