    Tips: Choose a VFD base on motor rated current

    When a motor power is stated, it is always the mechanical power, shaft power i.e. NOT the input electrical power.
    Variable frequency drives (VFD) are also (mostly) rated in terms of kW albeit it's wrong. Because VFD output is electrical (not mechanical). Mechanical power (i.e. motor shaft power) is always "active" power, where in electricity we also have reactive (doing nothing but losses) power. The apparent (total) power (stated in terms of kVA) is vectorial sum of active and reactive power components.
    For all those facts above, ATO highly recommend to select a VFD by matching motor current. This is the right way. Despite mathematically correct, we wouldn't select a VFD for partial load of motor. We would simply go for motor nominal (rated) current.
    Finally the answer is: choose a VFD output current ≥ motor rated current.

    How to run a three phase or single phase motor with ATO VFD on 120V power supply. Take a 2 hp, single phase 120V input, single phase or three phase 220V output variable frequency drive as an example. It shows you how to wire, set parameters, commissioning VFD, run motors, etc.

    Existing reviews of 1 hp VFD, Single Phase 120V Input, 1ph/3ph 220V Output
    Can you Have a this VFD run off of a 4-20ma input as well as run at a set speed?
    I would like to use DI1 to tell the vfd to run based on a 4-20ma input from AI1. Then I would like to use DI2 to tell the vfd to run a specific speed of 60Hz.

    Is this possible to do? If so what do I need to set?

    Also is there a complete manual that lists all the registers in the VFD? I am also curious where there is documentation explaining how to set up the Relay outputs.

    This VFD does not have the function of switching between 2 different frequencies. The relay output can be described in parameter F5-02.
    Can I connect the input to 120 VAC 60 Hz?
    Manual says to be used with a solar inverter, can I connect the input to 120 VAC 60 Hz?

    You can hook up the input to 120 VAC 60 Hz, but it will take more than 3x the power from the sun to run the VFD's rating.
    If the power is Not enough, the VFD will Not work.
    How to change the default frequency from 50 Hz to 60 Hz?
    I purchased a couple of VFDs from you and they say they can be changed to 60 hz from 50 hz default. I need to know how to please.

    If you want to get 60HZ output, just set F0-10=60, F0-12=60, you can try it.
    A couple of questions regarding this VFD
    I have a couple of questions regarding this 1-phase 115VAC VFD:
    Is the optimum potentiometer value used for a speed reference signal to terminal A11?
    I am using a foot pedal to control speed and have possible options of 1000, 5000 or 10,000 ohms, which is best?
    Foot pedal will also provide Run/Stop signal to drive via a single N.O contact.
    Contact closed = Run, Open = Stop.
    I also need to interface an E-Stop push button into this drive.
    Can you provide some guidance regarding the best way to wire your drive for this set-up. Any special parameter settings that I need for this set-up?
    I would like to configure Relay Output 1 and 2 to be:
    1=Run indicator light
    2=VFD Fault indicator light.
    What parameters need to be set to do this?
    Best Regards

    ATO Responded
    What is your order number? Please let us know so we can better help you. Hope you can understand.
    1. We recommend you use 1-5K ohms resistors.
    2. Connect the pedal switch to DI1 and COM, close to start, open to stop, please set parameter F0-02=1.
    3. F5-04=1 running output (corresponding to relay TA1 TC1)
         F5-02=2 fault output (for relay TA2 TC2)
         F9-09=0 (need to be set, otherwise the relay will not act when fault occurs).
    This VFD just doesn't work
    Finally received a replacement spindle motor to eliminate that as a potential issue but I get the same error 2. I have re-checked every setting many times and this thing just doesn't work. I don't know what else to do.

    Okay, in order to solve your problem as soon as possible, please feedback the following information:
    1.   Please send us your spindle motor nameplate label.
    2.   Please send a video to tell us how you set the parameters of the VFD. Please make sure the parameters of F1-01~F1~04 are correct. The video should show that when you finish the parameter setting, connect the spindle motor, start running, and then show the error code err02. You can send us the large video file via wetransfer.com.
    We want the protocol of capabilities on this modbus.
    For us, modbus is certainly good.
    Then can you give us the protocol of capabilities on this modbus?
    Then what type do you have in mind and then can you give us a graduated price please?
    Thanks.

    ATO Responded
    Sorry, we don't have a protocol of capabilities. Our products use the national standard protocol, and we use the MODBUS protocol that comes with the bottom layer of the TI chip. May I ask what architecture you use to make the bottom layer, the architecture generally has a protocol.
    Application Question
    1. I am looking to drive a spindle motor at 230v with 3.3FLA. (1HP) . Should I upsize and move to the 2hp unit?

    2. The table in the description listed rated current as 4 amps (7 amps for 2hp unit). Is this input or output rating?

    3. What are the recommended feeder circuits wire gauge and breaker amperage for both this unit and the 2hp unit?

    4. Do you recommend wiring in fuses before the VFD (i.e. slow blow fuse, etc)?
    From: Matt | Date: 18/07/2022
    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. Yes, it is safer to use 2HP capacity.
    2. 4A is the output rating.
    3. 1.5mm square wire is enough. The current of the circuit breaker should be more than 2 times greater than the output current of the inverter.
    4. A fuse can be added to the VFD input.
    Questions about 1hp VFD parameters
    For your 1hp variable frequency drives. Are the parameters saved when set, or is there a process to save them?

    The parameters are saved automatically when set.
    1 hp VFD delivery time
    We are looking into 1 hp VFD, single phase 120V Input, 1ph/3ph 220V output drive to control a couple fans, want to make sure we can control these with a pressure transducer having 0-10v dc signal? Also what is the lead time if we order two?

    1 hp VFD use
    Do I need an additional relay to use with the 1 hp VFD, or can I connect it directly to the motor?
    From: Garety | Date: 14/03/2021
    Was this review helpful? Yes No (0/0)

    Just connect the 1 hp VFD directly to the motor.
