Allen-Bradley 20DB028A0EYNANANE — PowerFlex 700S High-Performance AC Drive

AB · PowerFlex 700S · 480V 3-Phase · 28A · ~30 HP / 22 kW · NEW SEALED

The 20DB028A0EYNANANE is a Frame B member of the Allen-Bradley PowerFlex 700S AC drive family. It delivers 28 A continuous output at 480 V three-phase — roughly 30 HP / 22 kW in normal duty — with flux-vector control using Force Technology, an integrated SynchLink fiber port, encoder feedback slot, and Safe Torque Off (STO) safety. KOEED sources this catalog number brand-new factory-sealed for paper-machine sections, web handling, printing-register, extruders, hoist motions and heavy conveyor duty.

Key Technical Specifications & Overview

The catalog suffix breaks down as 20DB-028-A0-E-Y-NA-N-A: PowerFlex 700S platform, Frame B, 28 A nominal, no Human Interface Module (HIM) shipped in the box, SynchLink + enhanced control option, enhanced control firmware, no option module, no brake IGBT, 480 V AC. It is a high-performance vector drive — not a general-purpose 525 / 753-class unit — and is typically paired with Logix controllers in paper, printing, hoist and large-extruder cells.

Application Scenarios & Where It Fits

PowerFlex 700S is the high-bandwidth flagship of the PowerFlex lineup — chosen where a standard 753 / 755 cannot keep up. The 28 A Frame B unit drops into sections of paper machines, web-handling lines, printing presses, extruders, hoist motions and large mill / conveyor duty. Below are the most common fits for the 20DB028A0EYNANANE in particular.

• Paper-machine sections — dryer, calender, reel and size-press sections where web tension and register must stay locked across multiple drives.
• Web tension & printing register — SynchLink lets several 700S drives share a real-time fiber bus, ideal for printing-register control and unwind / rewind stands.
• Extruders & large draw-texturing — vector control with encoder feedback holds melt pressure stable on single-screw extruders and large draw-texturing lines.
• Crane & hoist — flux vector with STO safety covers hoist, trolley and long-travel motions on EOT cranes, where holding torque at zero speed matters.
• Mining mill & heavy conveyor — heavy-duty conveyors, SAG / ball-mill feed conveyors, and reclaim systems where 480 V three-phase power is available.
• Water & wastewater — large pump stations and aerator blowers driven from a Logix controller over EtherNet/IP.

Outside industrial automation? KOEED also stocks equivalent vector drives from Siemens, Mitsubishi, Yaskawa and Schneider for projects where the cabinet is not AB. Our AC drive collection covers all nine KOEED named brands — Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic and KEYENCE.

Integration & Wiring Notes

The 20DB chassis accepts a 20-750-series communication option card — pick the protocol your controller speaks. On the controller side, KOEED stocks the matching Logix hardware in our Allen-Bradley catalog: ControlLogix 1756-L7x processors, CompactLogix 1769-L3x processors, and PanelView HMI for local operator stations.

• Power wiring — 480 V three-phase to L1 / L2 / L3; motor leads to T1 / T2 / T3; PE to the chassis ground stud. Use 75 °C copper conductors and torque to the label value.
• DC bus & brake — this build (suffix N) has no internal brake IGBT, so an external brake resistor or regen unit must be sized for the application. Do not exceed the drive’s DC-bus capacitance rating during regen transients.
• Encoder feedback — wire the 11-bit or 17-bit feedback device to the integrated encoder port; keep the cable shield bonded at the drive end only, and route the encoder cable at least 200 mm away from VFD output power leads.
• SynchLink fiber — connect drive-to-drive with plastic optical fiber when running multi-drive shaft-locked coordination; do not mix with copper Ethernet cabling. Verify TX / RX polarity on each fiber link.
• Communication card — drop a 20-750-ENETR (EtherNet/IP), 20-750-CNETC (ControlNet), 20-750-PBUS (Profibus) or 20-750-PNET (Profinet) into the option slot; CIP messages are mapped through Studio 5000.
• STO safety — wire the Safe Torque Off input to a safety relay or GuardLogix safety output; the drive will not restart until both STO channels are released, in line with SIL 3 / PLe category 3 requirements.
• Control power — if the cabinet needs a stable 24 V supply for the option card, mount a Phoenix-Contact-class PS in the same enclosure and protect it with a dedicated breaker.

Installation & Commissioning Tips

PowerFlex 700S Frame B drives use forced-air cooling on the heat-sink side and still need airflow headroom. Most field issues on this catalog number are mechanical — fan guards clogged by cabling, missing finger-guards, or HIM-less startup attempts where the engineer was expecting a local keypad.

• Clearance — keep at least 100 mm above and below the drive, and 50 mm on each side; do not recess the heat-sink side into a sealed back-panel.
• Cooling — the Frame B fan runs whenever the DC bus is charged; verify finger-guards are fitted and that the fan spins freely before first power-up.
• First power-up without a HIM — this build (suffix A0) ships without a Human Interface Module, so plan on programming over EtherNet/IP from Studio 5000 / RSLogix 5000, or order a 20-HIM-A6 / 20-HIM-C6S HIM as a separate line item.
• Firmware check — confirm the firmware major / minor revision on the nameplate; pair with DriveTools SP or the KOEED AI diagnostic to pull a parameter file before the site visit.
• Motor auto-tune — run a static and a rotating auto-tune with the motor uncoupled where possible; record the resulting flux-current and slip values for the maintenance log.
• Spare pair — for a 24/7 paper, hoist or wastewater line, consider a cold-spare 20DB028A0EYNANANE on the shelf; we can hold stock for repeat customers with a Create a Quote blanket-order request.
• EOL awareness — PowerFlex 700S has been on the migration path to PowerFlex 755TM / 755TR. If you are mid-life extension, the AI diagnostic tool can suggest a 755TR cross-reference from your existing parameter file.
• Cabinet environment — keep ambient below 50 °C, with non-condensing humidity; use cabinet air-conditioning or a filtered heat-exchanger in paper-mill or wash-down areas.

Procurement, Warranty & Lead Time

KOEED ships the 20DB028A0EYNANANE brand-new factory-sealed — original Allen-Bradley carton, anti-static bag intact, nameplate serial visible. NEW SEALED is the listing condition code; it means a first-life unit that has never been energised. We do not resell pulled-from-service parts under that code, and we do not relabel refurbished drives as new.

Need a related option module, a 700S HIM, or a 755TR cross-reference at the same time? Send the whole instrument list to our RFQ desk and we will return a single combined BOM quotation.
