ATV71HD37N4: Variable Speed Drive
The ATV71HD37N4 is the Variable Speed Drive covered on this page. The attribute that decides whether it fits the existing installation without modification is 380-480 V AC.
This configuration's variable speed drive is the attribute that drives the replacement decision. A variable-speed or soft-start device is specified by the motor it must control and the starting or speed regime it must deliver. variable speed drive sets the current or power rating, the control method and the enclosure or network option — the things that decide whether the device starts the load without tripping and integrates with the existing control. Verifying 380-480 V AC against the motor nameplate and the control architecture prevents a drive that fits the panel but cannot carry the load.
