Testing the correct phase output without motor connected

What you want to do is wire three light bulbs or 230Vac small signal lights in a delta configuraton. Their links connected together one after each other so that you get 3 wire ends. Then connect this intersections to inverter phases. First you need to load Sine firmware so you are able to start in manual and command slip. Start inverter in "manual" mode.

If you now command fslip 1Hz and nominal motor amps 70% manually you should see lights blinking in 1/3s succession. fslipspnt - 1 ampnom - 70%

In case you have only two lights blinking and one not you know one phase is having some trouble.
