Schneider PN072130P905 Control Power Board – Tested ATV61/71

What Is the PN072130P905?

The Schneider PN072130P905 is the control-side power and interface board for Altivar ATV61 and ATV71 drives. It regulates the control-side voltage and provides the interface between the main control circuitry and the power stage. It is often supplied alongside the main CPU board VX4A71101 as a matched control set.

This is not the main CPU board and not the pure IGBT power board. It sits between them, handling control power and signal-level interfacing. Supplied as Tested / New stock — confirm condition per unit before ordering.

Key Specifications

When This Board Is the Suspect

• NLP (No Line Power) with DC bus voltage confirmed present — Schneider’s official guidance for ATV61/71 states that if the DC bus measures normal between PA+ and PC− but the drive reports NLP and the mains voltage menu shows no measurement, the probable cause is the power board, the control board, or the ribbon cable between them. 
• InFA (Internal Input Power Fault) — defined by Schneider as an internal input power fault; the input stage is not operating correctly。This points directly toward the control-side power management path that this board serves。
• Control power present at input but control circuitry unresponsive — supply voltage confirmed at the board input, but the control section does not initialize。

Compatibility Check

Before ordering, confirm:

• Original board marking — confirm the existing board reads PN072130P905.
• Drive series — confirm the drive is ATV61 or ATV71. This board is not the main CPU board（VX4A71101）and not the IGBT power board.
• Fault context — confirm whether the active fault is NLP or InFA. If the fault is a motor-side or output-side symptom（OCF, SCF, etc.），the relevant board is in the power stage, not this control power board。
• If unsure, send a photo of the original board label and the drive nameplate before purchase.

FAQ

Is PN072130P905 the main CPU board?

No. It is the control power / interface board. The main CPU board for ATV61/71 is a separate board，and the two are often supplied as a set. It is also not the IGBT power board.

Does NLP always mean this board is faulty?

No. Schneider’s NLP guidance lists the power board, the control board, and the ribbon cable between them as possible causes。Reseat and inspect the cable and power board before replacing the control board.

What fault does InFA point to?

InFA is an internal input power fault — the input stage is not operating correctly。It falls within the control-side power path this board serves, but the main control board should also be considered.

Condition & Dispatch

This board is supplied as Tested / New stock per the listing。Inspection covers connector condition, ribbon interface integrity, and board appearance. Photographic records are available on request before dispatch.
