Schneider Electric ATV900 Modbus register map

Also searched as: Altivar Process ATV900 · ATV930 · ATV950 · ATV960 · ATV980 · ATV9A0

1,911 Modbus registers of the Schneider Electric ATV900, with the address on the wire, the 30001-style reference, data type, byte order, unit and scale. Transcribed from ATV900 Communication parameters addresses (V4.6).

Altivar Process ATV900 drives (ATV930, ATV950...); every parameter is a 16-bit holding register at its logic address.

Hardware verification

Not yet verified on hardware. The map is transcribed from the vendor document and checked against it by script; check the first readings against the device display.

Verify it on your device What the levels mean

Connection notes

  • The embedded Modbus serial address is OFF from the factory; set [Modbus Address] (Add) before connecting.
  • Parameter codes (ETA, CMD, LFR...) are in each register's notes; the drive's display uses the same codes.
  • Writing CMD or setpoints moves the motor. Read-only access is the safe default.

Registers

Grouped as in the vendor document. Measurement, energy and identity groups are shown (300 registers); open any other group to load it.

Read it by name

Read the ATV900 with an AI assistant

The Proxus Industrial MCP Server includes this map. Set it on the device, and Claude, Cursor or VS Code reads registers by key with the right type, byte order, scale and unit. It only reads.

  "devices": {
    "atv900-1": {
      "protocol": "modbus-tcp",
      "host": "192.168.10.40",
      "unit_id": 1,
      "map": "schneider-electric/atv900"

  }
}

Ask your assistant

Read rfrd, rfr, otr from atv900-1.

The tool call it makes

read_named(device: "atv900-1", keys: ["rfrd", "rfr", "otr"])

Have this device? Verify the map.

Ask your assistant to run verify_device_map. It reads every register once, read-only, checks that the values are plausible and asks you to compare two values with the display. You get a report and a prefilled GitHub issue to submit; your name goes on this map’s verified list.

How verification works

Collecting from many devices?

Proxus reads Modbus TCP and RTU devices next to the machines, keeps the history and delivers the values to dashboards, databases and AI.
