Connection notes

Enable the EFB with 58.1 Protocol enable = Modbus RTU; node address is 58.3, baud rate 58.4, parity 58.5.
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 (FbEq 16b).
32-bit parameter access (420000 + 200 x group + 2 x index, word order 58.34, LO-HI by default) is not listed here.
This manual covers the AINLX primary control program; drives with the UCU control board (YINLX) have a separate manual, 3AXD50001000998.
Writing the control word or references moves the motor. Read-only access is the safe default.

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.

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.
