I couldn’t find a specific datasheet for 23km-c051-09v in my training data or live search results — it’s likely a custom or OEM part number (possibly from a motor, driver, sensor, or industrial component). However, I can give you a solid guide on how to locate and interpret such a datasheet, plus general steps to work with unknown part numbers.
Use shielded 18 AWG twisted-pair wire for each phase. Keep the cable length under 15 meters (50 feet) to minimize capacitance and voltage drop. Connect the shield to the driver’s earth ground terminal, not both ends (to avoid ground loops).
