          Questions buyers ask about 6SE6420-2UD21-1AA1

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • What motor load suits this MICROMASTER 420 rating?

            For high-overload duty use the 1.10 kW and 3.00 A rated output values to assess the load.

          • Does the 420 drive accept a 400 V three-phase supply?

            The specified input is three-phase 380–480 V AC ±10% at 47–63 Hz.

          • Can the FSA MICROMASTER rely on natural cooling?

            The unit is fan-cooled. Keep the air path clear and check the applicable enclosure conditions.

          • What pulse frequency is specified for the 1.10 kW drive?

            The data sheet lists 4 kHz. Review the approved settings before transferring parameters.

          • What frequency range applies in V/f mode?

            The documented V/f output range is 0–650 Hz. Set limits appropriate to the installed motor.

          • How should maintenance validate the MICROMASTER command source?

            Restore the configured run and speed sources, then test direction and speed under the site procedure.

          • What overload information should a MICROMASTER spare quote include?

            State high-overload duty and the motor nameplate current so selection is based on both ratings.

          • How can receiving identify the correct 420 voltage class?

            Check the full -2UD21-1AA1 marking and the three-phase 380–480 V label.
