Allen Bradley 20F1ANC456JN0NNNNN Air-Cooled AC Variable Frequency Drive (VFD)

FAQ

Q1: What is the Allen-Bradley 20F1ANC456JN0NNNNN used for?
A: The 20F1ANC456JN0NNNNN is designed for controlling large three-phase AC motors in heavy industrial applications such as conveyors, pumps, fans, compressors, crushers, and process machinery requiring precise speed and torque regulation.

Q2: What are the voltage and current ratings of this drive?
A: The drive operates on a 380–480 VAC three-phase power supply and provides a rated output current of 456 A. It supports 250 kW Normal Duty and 200 kW Heavy Duty motor applications.

Q3: Does the 20F1ANC456JN0NNNNN include a built-in braking transistor?
A: No. The 20F1ANC456JN0NNNNN does not include an internal dynamic braking transistor. External braking resistors and related components must be selected separately when braking performance is required.

Q4: What type of enclosure does this PowerFlex 753 drive use?
A: The drive uses an IP20/IP00 NEMA/UL Open Type enclosure and must be installed inside a suitable industrial control cabinet with proper ventilation and environmental protection.

Q5: Does the 20F1ANC456JN0NNNNN include a keypad or HIM module?
A: No. This configuration is supplied as Blank (No HIM). A compatible PowerFlex Human Interface Module can be installed separately for local programming, monitoring, and diagnostics.

Q6: What are the dimensions and weight of the 20F1ANC456JN0NNNNN?
A: The drive dimensions are approximately 1190 × 480 × 415 mm, and the weight is approximately 145 kg. Due to its high-power design, sufficient cabinet space and proper lifting equipment are required during installation.

Q7: What communication and expansion options are available for this drive?
A: The PowerFlex 753 platform supports optional communication modules such as EtherNet/IP and other industrial networks. Additional I/O expansion, encoder feedback, and safety modules can also be installed according to application requirements.

Q8: What should be checked before installing the 20F1ANC456JN0NNNNN?
A: Before installation, verify the incoming power supply, motor ratings, wiring, grounding, cabinet ventilation, environmental conditions, and drive parameter settings. If the application requires braking, confirm the external braking solution before commissioning.
