Series & Revisions

Series B in stock; other series on request.

Intended Use

Designed for high-performance vector drive applications. PowerFlex 700 drives handle demanding loads such as extruders, winders, cranes and hoists, centrifuges, test stands and large conveyors, with flux vector control, encoder feedback, torque control and DPI communication adapters.

Migration Path

Rockwell Automation has discontinued the PowerFlex 700. Published successor for the PowerFlex 700: PowerFlex 753 20F11ND027AA0NNNNN (same voltage class and normal-duty current), or the equivalent PowerFlex 755 (20G) for embedded EtherNet/IP and more option slots.

Rockwell's PowerFlex 700 to PowerFlex 750-Series migration guide carries a parameter cross-reference; parameters are re-entered or mapped, not copied, because the 750-Series parameter numbering differs.
The HIM and communication adapters change: 20-HIM-A3/A5 give way to 20-HIM-A6/C6, and 20-COMM-x adapters to 20-750-xxx option modules (the 755 has EtherNet/IP embedded).
Frame sizes and mounting differ between a PowerFlex 700 and the equivalent 753/755, so check the panel layout and the 750-TD001 dimensions before ordering.

A like-for-like replacement or a repair keeps the existing program, wiring and panel layout; a migration is a project. Both are listed on this page so the choice can be made on lead time and budget.

Common 20BD027A3AYNANC0 failures

Failure patterns we regularly see on PowerFlex 700 vector control AC drive hardware like the 20BD027A3AYNANC0:

20-COMM option or HIM communication faults (DPI port loss)
Gate driver or current sensor failure showing as erratic current readings
DC bus capacitor aging: undervoltage trips (F4) or a drive that will not finish precharge
Precharge relay / circuit failure leaving the drive stuck in precharge
Hardware overcurrent (F12) or ground fault (F13) from a failed power stage after a motor or cable short

Repair or replace?

ReplaceReplacement PowerFlex 700 vector control AC drive units are usually surplus or refurbished. Replace the 20BD027A3AYNANC0 when the motor is down and a same-rating drive is available. The parameters copy across with a HIM or DriveExplorer. Stick with the exact 20BD027A3AYNANC0. The suffix sets the 20 Hp, 480V AC rating, so a near match is a different unit. We have the 20BD027A3AYNANC0 in stock. Order before 5:00 PM Central and it ships the same day.

RepairAt 20 Hp, repairing the 20BD027A3AYNANC0 usually costs well under half of a replacement. Power modules, bus capacitors, precharge circuits and fans are replaced and the drive is load-tested, so you keep a drive whose parameters and option cards already match the machine. Most 20BD027A3AYNANC0 units reach our bench with one of two symptoms: “DC bus capacitor aging” or “Precharge relay / circuit failure”. Already swapped it out? Repairing the failed 20BD027A3AYNANC0 turns it into a tested spare, and on an older platform that spare can be hard to buy later. Our estimated $1,500.00 repair of the 20BD027A3AYNANC0 includes full-function testing and a 1-year warranty.
