FAQ
FAQ
Q1: What is the Allen-Bradley 20F1AND477AN0NNNNN?
A: It is a PowerFlex 753 variable-frequency AC drive designed to control the speed and torque of industrial three-phase AC motors.
Q2: What is its input voltage?
A: It operates on a 480 VAC, three-phase supply with an internal DC bus of approximately 650 VDC.
Q3: What are its rated current and power?
A: The drive is rated at 477 A, with 400 HP normal-duty power and 300 HP heavy-duty power.
Q4: Does this model include an internal dynamic braking transistor?
A: No. The exact catalog configuration specifies no internal dynamic braking transistor. An external braking solution may be necessary for applications requiring rapid deceleration or handling high-inertia loads.
Q5: Does it include EMC filtering?
A: Yes. EMC filtering is included. The common-mode capacitor jumper is removed in this configuration.
Q6: What are its dimensions and weight?
A: The approximate Frame 7 reference dimensions are 881.5 × 430 × 349.6 mm (H × W × D). A supplier lists 120.66 kg (266 lb), but this may represent shipping or listing weight. Confirm the actual unit and packaging dimensions before installation or transportation.
Q7: Does it include a built-in keypad or HIM?
A: No. This configuration is supplied without a Human Interface Module (HIM). A compatible HIM can be purchased separately for local monitoring and programming.
Q8: What is the replacement model?
A: Rockwell Automation identifies 20F1AND477JN0NNNNN as the direct replacement. The replacement has the common-mode capacitor jumper installed, so verify compatibility with the original installation before substituting.
