Schneider PN072130P902 Control Terminal Board – Tested ATV61/71

When This Board Is the Suspect

The control terminal board becomes the replacement target when signal-level symptoms persist after external wiring and parameter checks:

• NLP fault (No Line Power) with wiring confirmed — Schneider’s guidance for ATV61/71 states that NLP in most cases indicates a problem with the power board, the control board, or the cable connection between them . The control terminal board is part of this signal chain and should be inspected if the fault persists after reseating connections.
• Control inputs not responding — start/stop, frequency reference, or fault reset commands are correctly wired and configured but the drive does not respond. A damaged terminal block or poor terminal contact can interrupt the signal path.
• Analog/digital I/O instability — intermittent or offset readings on control terminals, with sensor/wiring verified normal.
• Visible terminal damage — cracked housing, loose or stripped terminal screws, or discoloration on the control terminal block.

Compatibility Check

Before ordering, confirm:

• Drive MLFB — the exact ATV61/71 catalogue number on the nameplate. The VX4A1104 kit is documented for all ATV61/71 frame sizes, but confirm your specific model against the manual’s frame table.
• Original board marking — confirm the existing terminal board matches PN072130P902 or VX4A1104.
• Terminal layout — compare the number and arrangement of control terminals against the original.
• If unsure, send a photo of the original terminal board and the drive nameplate before purchase.

FAQ

Is PN072130P902 the main control board?

No. It is the control terminal board (signal interface and terminal distribution). It does not contain the drive’s CPU or firmware. The main control board is a separate assembly.

Does NLP fault always mean the terminal board is faulty?

No. Schneider lists power board, control board, or inter-board cable connection as probable causes for NLP . The terminal board is one link in the signal chain. Reseat and verify wiring before replacing it.

Is VX4A1104 compatible with all ATV61/71 power ratings?

The official installation manual documents the VX4A1104 kit across ATV61/71 frame sizes from Frame 1 to Frame 15 . Confirm your exact drive MLFB against the frame table before ordering
