Hi all.
I have a project whereby multiple different motor arrangements need to be sync'd up. Normally this is no issue as we would use all DOL so the speed would vary with supply frequency or we use VFD's. This time, we will be mixing VFD's and DOL driven motors and I worry that if the supply frequency varies, the motors will be operating at different speeds. They are driving fixed flow hydraulic pumps so varying flow is not catastrophic, but undesirable.
There is no need for the VFD's in this application but the hardware is already installed so we want the VFD to vary the output frequency to match the input frequency. ABB ACS550 series.
Does anyone know if this is possible. I am not an EE and have limited experience/knowledge of these sorts of things.
