Frequently Asked Questions
What is the difference between the PowerFlex 4 (22A) and the PowerFlex 40 (22B)?
The PowerFlex 4 is the entry-level member of the family: V/Hz control only, 4 preset speeds, 2 programmable digital inputs, no analog output, no PID loop, and no StepLogic. The PowerFlex 40 adds Sensorless Vector Control with Autotune, 8 preset speeds, 4 programmable digital inputs, a bipolar ±10V analog input, an analog output, two opto outputs, integrated PID, StepLogic / Timer / Counter / Basic Logic functions, and a skip frequency. PF4 tops out at 5 HP; PF40 extends to 15 HP and includes a 600V 3-phase class that is not available on the PF4.
What is the migration path from a PowerFlex 4 / 40 to a PowerFlex 525?
The PowerFlex 525 (Bulletin 25B) is Rockwell's current-generation replacement for both the PF4 and PF40 at 0.4-30 HP. It is mechanically similar in many frame sizes but is not a bolt-for-bolt drop-in — terminal assignments differ, the parameter structure is new, and EtherNet/IP is built in rather than requiring a 22-COMM-E adapter. Plan for re-commissioning with Connected Components Workbench or Studio 5000 when retrofitting; consult Publication 520-TD001 before specifying the swap.
Are 22-COMM communication adapters compatible with both the PowerFlex 4 and the PowerFlex 40?
Yes, but the PowerFlex 4 requires the 22-XCOMM-DC-BASE external mounting kit to host a 22-COMM-x adapter; the PowerFlex 40 can mount the adapter directly under a 22B-CCB (Frame B) or 22B-CCC (Frame C) communication adapter cover, which adds 25 mm (0.98 in.) to the drive depth. The same 22-COMM-B (BACnet), -C (ControlNet), -D (DeviceNet), -E (EtherNet/IP), -L (LonWorks), and -P (PROFIBUS DP) adapter catalog numbers apply to both drives. A single 22-XCOMM-DC-BASE can serve up to five drives on one network node.
What enclosure ratings are available, and how do I convert an open-chassis drive to NEMA Type 1?
Standard packaging is IP20 / NEMA/UL Type Open (panel mount). Flange-mount (F-suffix) variants reduce overall enclosure size for door mounting. IP66 / NEMA/UL Type 4X/12 indoor is factory-available on PowerFlex 40 Frame B only (C-suffix). To field-convert a panel-mount drive to IP30 / NEMA/UL Type 1, order the 22-JBAA (PF4 Frame A), 22-JBAB (shared Frame B), 22-JBAC (PF40 Frame C), 22-JBCB, or 22-JBCC conversion kit — each includes a conduit box, mounting screws, and plastic top panel.
What fusing and branch-circuit protection does Rockwell specify?
Recommended fuses are UL Class J, CC, T, or Type BS88 600V (550V) or equivalent, sized per the catalog-specific ampere rating in the Drive Ratings tables. Rockwell also lists Bulletin 140M / 140MT motor protectors and 100-C / 100-E contactor pairings for every catalog number. For IEC applications with DC-bus terminals in use, a DC fuse is mandatory on the internal dynamic brake circuit — Rockwell specifies Bussmann PV-series fuses plus Hinode 1000GH fuses by rating. Manual Self-protected Type E combination controllers are UL-listed for 208 Wye/Delta, 240 Wye/Delta, 480Y/277, and 600Y/347 systems — they are NOT UL-listed on 480V or 600V Delta/Delta, corner-ground, or high-resistance-ground systems.
Is the PowerFlex 4 or PowerFlex 40 still manufactured?
Publication 22-TD001 is still maintained (revision J, September 2024), which means Rockwell continues to produce and support the family. However, the PowerFlex 525 is the current-generation preferred drive at this power level for new machine designs. Use the 22-TD001 ratings and catalog-number tables for spare-parts sourcing, drop-in replacements, and OEM installations already standardized on the 22A/22B platform.
