Control Techniques Commander C200/C300 drive (needs AI-485 adapter)

Register map(s) for this device, each at the trust rung it earned. Addresses are 0-based as on the wire; word order and scaling are only confirmed at the hardware-verified rung.

interop-verified

Read + decoded cleanly over a real network vs an independent third-party Modbus test server (transport and framing; reads are remapped into the server's register window, so the map's own addresses are NOT exercised). Does NOT prove word order/scaling against the actual device.

link settings as documented (unverified): RTU; default 19200 8N2; unit ID 1; FC 03,06,16,23; The communications port applies a 1.25 unit load to the communications network. Default setting is 8 2 NP (8 data bits, 2 stop bits, no parity).

⚠ The STOP and Safe Torque Off functions of the drive do not isolate dangerous voltages from the output of the drive or from any external option unit. — Starkest reads only; we never write a control register.

bench facts as documented (unverified)
terminalsRJ45 or screw terminals
A/B polarity
termination120 Ohm termination resistor available on RJ45 pin 1 or screw terminal pin 4
connectorRJ45 or screw terminal block
isolationSingle insulated, meets ELV requirements
shield/groundMinimum number of connections are 2, 3, 7 and shield
wiring notesStandard Ethernet cables must not be used when connecting drives on a EIA 485 network as they do not have the correct twisted pairs for the pinout of the serial comms port.

sentinel values
protocol notesThe Modbus slave device increments the register address by 1 before processing the command, which effectively prevents access to parameter Pr 00.000 in the drive or option module.

The trust ladder

Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.

Have a device that isn't here? Upload its register map — generation is free, and the connector earns its rung by being proven, not claimed.

Need it proven on your own device? Hardware verification — if it doesn't verify, you don't pay.

Building a platform? License the verified library — machine-readable maps, firmware matrix, API access.
