Inverter does not give voltage signal

Seguir
Good evening classmates
I have a HOLIP HLP-A100 Speed ​​Inverter for a three-phase 4HP motor, the Inverter is powered from the mains to 220 volts two-phase and outputs 220 volts three-phase taking into account that the input can also be connected to 220 three- I came from factory and maybe they configured it well, well the problem is that it does not give me constant output signal bone in the multimeter oscillates the voltage a lot and I guess it came from factory because we are just going to release it again, I deduce that is some parameter that is misconfigured because the multimeter starts reading 240 volts AC and then marks voltages occilantes in CD of 30 40 50 and thus many values ​​but the voltage is not sustained and less in alternating, it is worth noting that the Inverter is new and we are just going to work, but I arrive this way from the factory and the manual is in English and I need your help please help me.

Hi. Does the appliance work? What would be your query? With a common tester you will not be able to check the voltage since the frequency is variable at all times. regards

    Hello servimat1 good morning thanks for answer, look my question is how do I know if the parameters are well programmed since you do not navigate the display of the variator and then what happens is that when checking output voltage is not held and the clamp voltiamperimetrica that used for this measurement is a Uni-t200, it should be noted that the Variator outputs a control signal of 24 volts and goes to a timer of double knob one off and the other on and changes state every 5 minutes, from factory, what's that sign for? the motor is not connected even to the drive

    I would like to know if placing the other phase in the input would have to change some parameter thanks

    The truth to this variador I do not know it. Usually with the ones I have worked on (WEG) it is not necessary to change any parameters. regards

    Ok I understand but to all this I get a doubt is that a speed variator works equally with two phases with three thanks and forgives my ignorance. Blessings

    This is usually done for a matter of engine power and more efficient use of energy. depends on each model also but always depends on the power of the engine. In any case, the drive "manufactures" the missing phase (s) for the motor to run. regards

These oscillations occur because the output frequency is switched and your measuring device is not able to measure it. Test with a multimeter that gives you true value. (TRUE RMs).
I for example use a fluke amperometric clamp to measure that output voltage.
