    Note: The single 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.
    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.

    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.
    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.
    Use of single phase VFD
    Can a single phase VFD work with a shaded pole AC motor?
    From: Kamryn | Date: 07/05/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, It works for single phase motor and split phase as well.
    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.
    From: Laurilee | Date: 25/08/2021

    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.
