Hi everyone. Does anyone have experience driving EBM axial fans with Variable Frecuency drives ? More specifically, we are trying to set up condensing temperature control for a chiller which has 2 A6D910 fans with a Schneider ATV310HU15N4 VFD.

The thing is, EBM says they do not recommend using fans with VFDs beause there is a potential bearing premature damage and we have reasons to believe this maybe true (but thousands of different applications with VFDs claiming they are perfectly ok to be used).

Regards
