Hi Viesturs . Could you please specify the motor data and the VFD data (manufacturers + material code) ? I never seen any VFD to control 2 motors in "series" connection . The high speed motors are equivalent to asincronous or they are not ? A standard VFD (V/F or sensor less vector) can control this kind of motors ? Maybe you have to tweak some parameters into the VFD (such as electrical motor data) to best fit the electrical motor characteristics .
