Frequently Asked Questions
What is the Allen-Bradley 20F1AND248AN0NNNNN?
It is a Rockwell Automation PowerFlex 753 variable frequency drive with embedded I/O, a 480 VAC three-phase input configuration, 248 A continuous output current and a Frame 6 open-type enclosure.
What is the normal duty motor rating?
The normal duty rating is 200 HP, approximately 150 kW. Actual motor selection must be based on the drive output current rating, motor nameplate and operating conditions.
What is the heavy duty motor rating?
The heavy duty motor rating is 150 HP, approximately 110 kW. Applications with significant overload requirements must be evaluated using the relevant manufacturer overload and derating specifications.
What is the drive's rated output current?
The manufacturer specifies 248 A. Confirm the required duty classification and motor full-load current before selecting the drive.
What input power supply is required?
The catalog number identifies a 480 VAC three-phase drive. Supply tolerances, upstream protection and wiring requirements must follow the applicable PowerFlex 750-Series technical documentation.
Does the drive include embedded I/O?
Yes. The 20F1AND248AN0NNNNN is a PowerFlex 753 drive with embedded I/O for supported control and monitoring functions. Confirm the required terminal functions and parameter assignments during commissioning.
Does this PowerFlex 753 include built-in EtherNet/IP?
No. EtherNet/IP connectivity requires a compatible optional communication module. The PowerFlex 753 should not be assumed to have the same integrated network hardware as a PowerFlex 755.
Is a Human Interface Module included?
No. This configuration is specified with a blank operator position and no HIM. A compatible operator interface must be selected separately when local display or keypad operation is required.
Does the 20F1AND248AN0NNNNN have an internal braking transistor?
No. The catalog configuration specifies no dynamic braking hardware and does not include an internal braking transistor. Applications requiring braking must be engineered using supported external solutions.
What is the drive frame size?
The 20F1AND248AN0NNNNN uses Frame 6 construction. Mechanical clearances, mounting arrangements and cabinet ventilation should be checked against the applicable installation documentation.
What enclosure rating does the drive have?
The drive is specified as IP20/IP00, NEMA/UL open type. It requires installation in a suitable protective enclosure based on the industrial environment and electrical safety requirements.
Does the drive include an EMC filter?
Yes. The drive is configured with EMC filtering and the common-mode capacitor jumper removed. The jumper configuration is an important part of the full catalog identification.
What is the difference between 20F1AND248AN0NNNNN and 20F1AND248JN0NNNNN?
Both are PowerFlex 753 drives with the same 480 VAC class, 248 A output current and 200 HP normal duty rating. The 20F1AND248AN0NNNNN has the common-mode jumper removed, whereas the 20F1AND248JN0NNNNN is configured with the jumper installed. The grounding arrangement must be reviewed before substitution.
Is the 20F1AND248AN0NNNNN discontinued?
Yes. Rockwell Automation lists the product as Discontinued, with a discontinuation date of June 30, 2024.
What is the manufacturer-listed replacement?
Rockwell Automation identifies 20F1AND248JN0NNNNN as the direct replacement. Although the manufacturer classifies it as a direct replacement, the EMC and common-mode configuration difference must be considered before installation.
Can the drive be used with industrial PLC systems?
Yes. Compatible PLC-based control systems can interface with the drive through supported embedded I/O and optional communication hardware. Network modules, control logic and drive parameters must be selected for the intended system.
Can this model be connected directly to an external DC bus?
The specified input configuration uses an AC input with precharge and has no DC terminals. It should not be selected for an application requiring external DC-bus terminals without reviewing an appropriate alternative drive configuration.
What should be checked before ordering?
Confirm the exact catalog number 20F1AND248AN0NNNNN, 480 VAC three-phase input, 248 A continuous output, 200 HP normal duty and 150 HP heavy duty ratings, Frame 6 enclosure, embedded I/O, forced-air cooling, no HIM, no internal dynamic braking transistor, no DC terminals and EMC filter with common-mode jumper removed. If considering the replacement 20F1AND248JN0NNNNN, verify the common-mode jumper and grounding requirements with the system design.
