ABB ACS580 Modbus register map

Also searched as: ACS580-01 · ACS580-04 · ACS580-07 · ACS580 standard control program

31 Modbus registers of the ABB ACS580, with the address on the wire, the 30001-style reference, data type, byte order, unit and scale. Transcribed from ACS580 standard control program firmware manual (Revision J, 2025-10-06).

ABB ACS580 general purpose drive over the embedded fieldbus (EFB) Modbus RTU interface; ABB Drives profile words and key 16-bit actual values.

Connection notes

  • Enable the EFB with 58.01 Protocol enable = Modbus RTU; node address is 58.03, baud rate 58.04, parity 58.05.
  • The manual writes holding registers as 6-digit references (400001...); the address here is the reference minus 400001.
  • Registers 400001-400006 hold the defaults of 58.101-58.106 Data I/O 1-6 and change if those are re-mapped.
  • Parameter registers use 58.33 Addressing mode = Mode 0 (default), 16-bit access, register = 400000 + 100 x group + index; values use the parameter's 16-bit fieldbus scaling (FbEq16).
  • 32-bit parameter access (420000 + 200 x group + 2 x index, word order 58.34, LO-HI by default) is not listed here.
  • Writing the control word or references moves the motor. Read-only access is the safe default.

Read it by name

Read the ACS580 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.

This device speaks Modbus RTU: reach it through a Modbus TCP gateway and use the gateway’s address with the device’s unit ID.

Ask your assistant

Read control_word, reference_1, reference_2 from acs580-1.

The tool call it makes

read_named(device: "acs580-1", keys: ["control_word", "reference_1", "reference_2"])

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.
