Note:

The single phase motor should Not be adjusted to run based on a lower frequency than 80% of its rated frequency for along time, otherwise the motor may fail.
ATO VFD Cannot be used as a power source, it Can only be directly connected to an induction motor to control the motor speed.
Single phase VFD Cannot control the motor in reverse, if you want to reverse the motor, refer to the motor nameplate instructions for operation.

Tips: Commissioning of single phase VFD with PC
After the basic settings of VFD, it can be connected with PC for the whole system commissioning. Connect the control lines of the VFD with the PC, and change the VFD operation mode to terminal control. According to the requirements of the PC system, set the VFD receive frequency signal range to 0~5V or 0~10V, and set the sampling response speed of analog frequency signal. If additional monitor is required, select the analog output monitoring item and adjust the range of this monitoring item terminal.

Running a single phase motor with VFD

In this video, ATO will show you details about running a single phase motor on a VFD. It's important to note that there are two wiring methods for single phase motor connecting to ATO single phase VFD: wiring of removing motor capacitor & wiring of keeping motor capacitor. At first, you should choose the wiring method you needed, and then set basic parameters step by step.

How to read the Inverter Fault when OC1 is configured to output it?

I got the e-stop button wiring figured out. I tried to do both a terminal stop command and a VFD Run Prohibit, but the spindle would just coast to a stop. I then disconnected the VFD Run Prohibit and it did what I needed. As a bonus, since the estop button is latching, stop command is continuously being applied, thus preventing the spindle from being restarted until the estop is deactivated. The only thing I haven't figured out is how to read the inverter fault when OC1 is configured to output it. There does not seem like enough voltage across the terminals to be able to activate a LED nor to energize a relay. How do I read the inverter's faults?
