    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?

    The fault output of VFD is generally output through the TA/TB/TC terminal of the relay, and the corresponding parameter is P4.12=15 (VFD fault). TA-TB is a normally open contact, and TA-TC is a normally closed contact, similar to a switch.
    About VFD setup
    I have a VFD, and I need to configure it to respond appropriately to an E-Stop activation. From reading the manual, I believe I need to set two input terminals, one to option 11 (External Stop Command) and another to option 13 (Inverter Running Prohibited). Are these the two correct settings I need to configure or do I not need one of them or do I need to configure additional/other settings? I have successfully activated the external stop command, but do not know how to activate the "Inverter Running Prohibited" option. How do I activate this setting? Do I close the connection from this input terminal to COM (or GND) or do I need to connect it to an external positive voltage source (5V, 12V, or 24V)? To activate this setting, is it a momentary connection (like it is to activate the external stop command) or does it require a continuous connection for the duration the VFD needs to be prohibited from running. To exit this state (to be able to run the VFD again), does the VFD need to be reset, power cycled, or will simply opening the connection be sufficient?

    For the start and stop signals of VFD, please refer to the following instructions:
    1.VFD wiring:
    Start switch: the start switch (Normally open contact NO)is connected to terminal FWD and terminal COM
    Stop switch: The stop switch (Normally open contact NO) connect the stop switch to terminal COM and terminal X1.
    2.Set as following:
    P0.03=1 (run command from terminal)
    P4.08=0 (2-wire control mode 1)
    P4.00=13（Define terminal X1 as stop signal）
    When you press Emergency stop, X1 and COM will be connected, and VFD will stop.
    And you can also refer to the video for VFD terminal control: https://www.youtube.com/watch?v=nBUm4i9wnzY&list=PLlo8RulDRnthBFbP4ydheukDSKw2hAfDn&index=12
    The VFD does not drive the motor.
    I received this shipment last week in good condition. During installation yesterday, I can only get one of them to output a voltage and it works fine. The other one appears to work fine, but it does not output a voltage/current and there is no error or fault even though the display shows it ramping up and down - the current is always 0.00. All settings are exactly the same on both units. I thought it might be one of the filters that was bad, but even when the filter is bypassed, the VFD does not drive the motor.

    To solve your problem,
    1. Please provide us with the nameplate of the VFD for confirmation.
    2. Please provide us a video showing the problem you describe. The video should show that the VFD is already running at 60HZ, but has no output voltage.
    3. You can set the VFD parameter to P3.01=10 (restore the factory parameters), running the VFD with no load, and when the frequency runs to 50/60HZ, using a multimeter to measure whether the VFD output terminals U-V, V-W have output voltage.
    Single phase motor with no chance to re wire it
    Can i connect to a single phase motor of 7.5 HP that i can't remove the capacitors this model? Also what size of wire can  the sockets support, cause i have a 4 AWG on the output for the motor.

    ATO Responded
    1. It can be connected to a 7.5HP single-phase motor, but the rated current of your motor should be less than 49A.
    2. It is generally not recommended to remove the capacitor.
    3. Sorry, I don't quite understand which socket you mean by "socket", you can send your questions to this email support@ato.com, our technicians will answer your questions.
    Do you offer external potentiometer for external speed controls for your 1 phase drive?

    Our VFD has a potentiometer beside its operation panel, and also you can install an external one if needed.
    I have a question about VFD for you
    Can this single phase VFD be applied to any type of 1 phase motor? I have a 240VAC supply fan for an indoor air handling unit and would like to control the speed to values other than the 3 speed settings that are available from the motor taps.

    ATO Responded
    As long as your motor is 1-phase, induction motor with running or/and starting capacitors, 220/230/240V, then you can use our 1-phase drives. You can send us your motor name plate "tag label" picture or inform us about its rated voltage, and current.
    Use of single phase VFD
    Can a single phase VFD work with a shaded pole AC motor?
    From: Kamryn | Date: 07/05/2021

    ATO Responded
    Yes, It works for single phase motor and split phase as well.
    Benefits of removing the motor capacitor
    What is the advantage of removing motor capacitors when installing your 1 phase variable frequency drive?
    From: Sharon | Date: 29/03/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    It is okay to remove the capcitors or not, the drive will work effectively. Just removing capacitor may provide little bit stability.
    Single phase output VFD operation
    I am interested in single phase output VFD. Can I run multiple fan motors on one drive?
    From: Mcclellan | Date: 25/03/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, you can. But run all at the same instant from the drive.
