FAQ
FAQ
Q1: What is the Allen-Bradley 20F1AND477JN0NNNNN?
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: The drive is designed for a 480 VAC, three-phase power supply, with an internal DC bus of approximately 650 VDC.
Q3: What are its current and power ratings?
A: The normal-duty rating is 477 A and 400 HP (approximately 298 kW). The heavy-duty rating is 300 HP (approximately 224 kW), with an output current of approximately 361 A.
Q4: Does this model include an internal dynamic braking transistor?
A: No. This catalog configuration does not include an internal dynamic braking transistor. An external braking solution may be required depending on the application’s deceleration and load requirements.
Q5: Does it include EMC filtering?
A: Yes. EMC filtering is included, and the common-mode capacitor jumper is installed.
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 the weight as approximately 106.14 kg (234 lb). Confirm the actual unit and packaging weight before installation or shipping.
Q7: Does the drive include a built-in keypad or HIM?
A: No. This configuration is supplied without a Human Interface Module. A compatible HIM can be purchased separately for local monitoring and programming.
Q8: Is the 20F1AND477JN0NNNNN still available?
A: Rockwell Automation lists this model as active. Availability and lead time may vary by region and distributor. It is also identified as the direct replacement for 20F1AND477AN0NNNNN.
