Tips and Tricks

An inverter is not a PLC! It is not possible to simply replace the inverter and the motor to get the same result. You should understand that the vector motor operation mode is set in the inverter by default (P00,00=1 ) . This mode involves building a virtual model of the motor to create a control vector at the three-phase output. The model includes engine parameters from the nameplate and additional parameters that the inverter can measure in tuning mode. If you switch the operation mode in the small inverter to 2 (this is the simplest mode without current vector generation), then there will be no need to generate the motor model. And if the inverter and the motor are in workingcondition, then everything should start working (on the same PLC setting). Next, you follow the path described by me above - adjust the motor parameters and perform auto-tuning. P.S. When sitting in a car of different sizes, you must adjust the height of the seat and the distance to the steering wheel. Now you are in a situation where you changed the car to a smaller one and for some reason you cannot see the road... You are definitely sure that you know how to drive a car. Just adjust the seat - the car is in good condition

The settings on the two VFDs are the same. Still it works if we change to the larger model, without any changes.    Small VFD Model: UMI-0022EE - B1  2,2 kW Normal VFD model: UMI-0040EE - B1 4kW

I think this is about analog OUTPUT , and it is corect .

As a kid, I used to watch The Wizard of Oz and wondered how someone like Scarecrow could talk if they didn't have a brain. Then Facebook came along......

Somewhere in the scheme of things, reference to using my forum name as password has gone missing.  ???    It's now back.   Just maybe I didn't have it there in the first place!  😖 Anyway, as others have said, different makers have vastly different ways of doing things. I'm sad for you because I could have recommended a small book I had years back that assisted my learning curve, but it appears to have gone to the paper gods during a bookshelf clean-up/huge office re-arrange some time back.  I'll keep my eye out for it, as it was the sort of thing I would never  throw out, but likely by the time it shows up you will be proficient! cheers, Aus
