RS-485 Modbus Servo Motors

RS-485 servos run on a two-wire differential bus, so they tolerate cable runs and electrical noise that would corrupt a single-ended signal, and several servos can share one pair.

One caveat matters before you write controller code: not every model in this category speaks Modbus. The industrial series (9100 and above) is documented as RS-485/Modbus, while the brushless low-profile and 8-series builds carry an inspection sheet that lists RS485 as the command signal and nothing more. Each product page states which one it is — do not assume a Modbus dialect from the category name.

Register maps, function codes and bit rates are supplied per model on request.
