    We have a Huanyang hy02d223b frequence convertor, and we obtain the problem that we can drive a motot of 2,2 Kw 1750Rpm, but no pmower is driving the motor, i.e. the motor runs untill a well definedlower frquence, but above that frequence the motor does’nt turn anymore, althoughwe hear in the motor that the frequence ( sound in motor ) amounts in functionof the pot meter setting.

    We thing ithas something to do with the parameter setting in the convertor, but did’nt find the solution untill now.

    Has anybody some idea about the reason of this problem ?
