Information
- Allen-Bradley 80026-044-06-R serves a defined point in the PowerFlex 7000 IGDPS circuit path. Separating the source, connections and monitored output helps locate the actual cause of a supply-related fault.
Gate-drive output: 20 VDC
Output diagnostic tolerance: +/-2%
Gate-supply diagnosis compares the nominal 20 VDC output against a +/-2% window. A low gate-supply event requires inspection of output voltage and its connections; the diagnostic state of a gate driver cannot be explained by the IGDPS part number alone.
For IGDPS 56V Loss, inspect the AC/DC output, IGDPS input and supply wiring. Compare the measured ACB J15 voltage with the value in P101. A valid physical 56 V reading paired with a lower reported value directs attention to the measurement/control path rather than automatically condemning the supply.
80026-044-06-R Official Technical Excerpt
The original technical excerpt for Allen-Bradley 80026-044-06-R covers exact supply identification and applicable fault investigation. PDF · 4 pages.80026-044-06-R Installation & Verification Guide
Apter Power installation and verification guide covering power-path identification, connection restoration and diagnostic comparison. PDF · 5 pages.
Application scope: Use the exact supply selection within the stated platform. Similar output voltages do not establish compatibility with a different source or gate-drive board.
Auxiliary source verification
Keep AC/DC source failures, IGDPS 56V Loss and gate-output faults distinct. Their diagnostic names point to different parts of the auxiliary circuit.Controlled circuit replacement
Mark the incoming auxiliary feed and outgoing gate-power connections. Inspect for loose, damaged or incorrectly seated connectors.Diagnostic comparison
Under the authorized test setup, compare AC/DC output with the voltage at the IGDPS input. Correct wiring loss before evaluating the converter.System recovery
For fault 53, measure ACB J15 and compare with P101. A normal physical rail and low displayed value call for control-path investigation.
Apply the approved medium-voltage and control-power isolation, discharge and verification procedure before accessing the supply or gate circuitry.
Mark the incoming auxiliary feed and outgoing gate-power connections. Inspect for loose, damaged or incorrectly seated connectors.
Match the complete 80026-044-06-R identity and installed assembly. Do not substitute a similarly numbered board with a different input or output arrangement.
Under the authorized test setup, compare AC/DC output with the voltage at the IGDPS input. Correct wiring loss before evaluating the converter.
Measure the nominal 20 VDC output at the prescribed points and compare it with 19.6-20.4 VDC. Include the affected gate-driver power connection.
For fault 53, measure ACB J15 and compare with P101. A normal physical rail and low displayed value call for control-path investigation.

Technical notes
Two-stage supply checks: Verify the upstream 56 VDC source and the downstream gate-power output separately. The IGDPS is one stage in the drive auxiliary-power path.
Metering comparison: A discrepancy between physical voltage and reported voltage can involve the control or feedback path. Compare the prescribed test points before deciding which assembly to replace.
FAQ View All FAQ
-
What voltage conversion is associated with 80026-044-06-R?The PowerFlex 7000 IGDPS selection is 56 VDC input to nominal 20 VDC gate-drive power.
-
Is 80026-044-06-R the single-phase AC/DC source for the drive?No. It operates downstream of the 56 VDC auxiliary source. The AC/DC converter is a separate component.
-
Which output window is used when diagnosing 80026-044-06-R?The gate-supply procedure uses 20 VDC +/-2%, equivalent to 19.6-20.4 VDC.
-
What does IGDPS 56V Loss mean for the circuit feeding 80026-044-06-R?The drive has detected loss of the 56 VDC feed. Inspect source output, connections and IGDPS input before selecting a replacement.
-
Why compare ACB J15 with P101 when investigating 80026-044-06-R?J15 provides a physical supply measurement while P101 reports the processor-observed value. Disagreement can identify a measurement/control-board issue.
-
Does a correct 56 VDC input prove the outputs of 80026-044-06-R are healthy?No. Verify the gate-supply outputs and their connections separately against the 20 VDC diagnostic window.
-
Can reconnecting a feedback fiber change the diagnostic state associated with 80026-044-06-R?The drive guidance notes that TFB fiber removal or insertion can cause a low gate-power event. Follow the specified reset and voltage verification procedure rather than assuming permanent supply failure.
-
What should be checked if 80026-044-06-R is replaced but gate-power faults remain?Check output voltage at the affected gate-driver path, connector seating, the upstream 56 VDC source and the drive feedback/measurement circuit.
