20F11NC2P1JA0NNNNN Variable Frequency Drive PowerFlex 753 0.7kW 3-ф/380

20F11NC2P1JA0NNNNN — PowerFlex 753 rated 0.7 kW, three-phase 380V supply, 2.1 A rated current, IP20. The smallest item in this lineup — for small drives in systems already controlled by an Allen-Bradley controller.

Typical uses:

• Small fan or extractor in a control cabinet
• Dosing or small process pump
• Short conveyor or feeder within a ControlLogix line

Note: three-phase 380V, no factory EMC filter and no installed option modules — EtherNet/IP and extra I/O are added separately. Outside the Rockwell ecosystem a Veichi AC10 is usually better value at this power.

Allen Bradley PowerFlex 753 — modular VFD for plants standardized on Rockwell

In short: the 753 (catalog prefix 20F) is the general-purpose member of Rockwell Automation's PowerFlex 750-Series. Its real strength is not price or any unique drive spec — it is deep integration into the Allen-Bradley world: ControlLogix/CompactLogix PLCs, EtherNet/IP networks and the Studio 5000 environment. If your line already runs on that hardware, the 753 drops in cleanly. If it does not, we will say it straight: paying the premium makes little sense.

In this lineup we list models from 0.7 to 55 kW, all three-phase 380V input and output, IP20. That is only part of the full 750-Series range (up to 250 kW per the manufacturer). Every item here ships without a factory EMC filter and without installed option modules.

What the 753 is for

• Ventilation and AHU: supply/exhaust systems with variable-torque loads — typical 753 duty.
• Pumps: water supply and process pumps, usually in the 4-55 kW band.
• Conveyors and material handling: where the drive must take commands from ControlLogix over EtherNet/IP.
• OEM machines: machine builders standardized on Allen-Bradley who do not want a zoo of brands.

What sets the 753 apart

Slot-based architecture: three option ports (4, 5, 6) for I/O, feedback, safety or communication modules — so you pay for what you actually need. Control modes are V/Hz, sensorless vector and flux-vector with FORCE technology. It has built-in I/O, an optional Safe Torque Off functional-safety feature (Safe Speed Monitor certified to PLe/SIL3) and predictive diagnostics for the cooling fans. EtherNet/IP at the series level is delivered by a separate dual-port module — on our specific SKUs it is not factory-installed and is added separately. The manufacturer claims Premier Integration with Studio 5000 cuts drive-system development time by up to roughly 70% — that is Rockwell's marketing figure, but the direction holds: PLC and drive are configured in one project.

753 vs 755 and cheaper alternatives

Choose the 755 when you need built-in EtherNet/IP, permanent-magnet motor control and 5 ports. PID is identical on both. If the plant is not on Allen-Bradley, a Veichi AC310 is most likely the better value: the same pump-and-fan duty, simpler standalone start-up and a noticeably lower price.

When the 753 is NOT the right pick

• Single-phase 220V mains — not offered here; see Veichi AC10 (1x220).
• You need a cheap standalone drive outside the Rockwell ecosystem — take a Veichi AC310.
• You need a factory EMC filter or comms module out of the box — on these SKUs those are separate options.

Our experience

From what we see, the 753 is bought mainly to integrate into existing Allen-Bradley lines, less often as a standalone drive. A common buyer question is whether these models ship with EtherNet/IP and a filter out of the box. The honest answer is no — those are options, and we flag it before the order. Another recurring question is matching to a 380V three-phase mains; every item here is built for exactly that.
