What this cable does in your ET200X system
The 6ES7194-1LD00-0AA0 is a 10 m motor cable for connecting a frequency converter (FU) to the motor in a Siemens ET200X distributed I/O system. Rated for the drive-side wiring in the ET200X family, it carries the motor power from the inverter output to the motor terminals, shielded for the EMI environment common in drive cabinets.
At 10 m, this cable covers the typical distance from a drive cabinet to the motor on a conveyor, pump, or small machine station — long enough to reach across a machine bed but short enough to keep the inverter-to-motor lead within the manufacturer's recommended length for the carrier frequency.
