Re: Spindle and VFD pairing
A VFD when powered Charges a large 3phase rectifier fed Capacitor reservoir bank, this DC reservoir bank will be (or should be) kept charged to keep up with the anticipated demand of the 3ph switching circuit.if the drain on the bank is low, then the re-charge (supply) current demand is also low.
e.g. When the motor output is zero, then the current demand on the bank is comparatively zero also.
