deVIce structure & IsolatIon
This graphic shows the electrical structure of the drive, detailing the elements that share a common circuit
common (Signal Ground, HV Com) and circuits that are isolated and have no connection to internal circuits.
note that there is no connection between the heatplate (Chassis, frame Ground) and any drive circuits.
