Servo cables aren't usually an area of focus at the beginning of motion control design; however, many motion faults begin at the cable. Servo cables that are designed for continuous flexing, for reliable and stable feedback transmission, and for noise-free communication between the servo drive and the motor can significantly reduce faults caused by cabling. For example, in a high-speed application, if there is a cable signal loss or shielding failure, positioning accuracy will be immediately affected. Therefore, when selecting cables, it is critical to consider many factors such as the type of servo drive, the motor rating, the routing path, and the bending radius of the cable, not just compatibility with the connector.
Cables in our inventory include LXM23 and LXM26 series, Schneider reference numbers VW3M5101, VW3M5102, VW3M5104, VW3M5105, and VW3M8102 along with encoder cables and hybrid power with data assemblies. The outer sheath material is chosen based on how the cable will be routed, through a tray or drag chain, or connected from the panel to the machine. Double-shielded cables wired according to proper grounding practices will protect the cable from electrical noise in industrial environments where VFD panels, motor control panels, and high-current feeders run parallel to each other.
Length matching is considered a critical factor for performance; excess coiling within the panel creates unnecessary heat and signal disruption while significantly increasing the stress on connectors when cabling is routed too short. We will confirm the correct pin configuration, brake core requirement, earthing continuity, etc., prior to shipping. Once our servo cables are installed into US automation lines, they are able to support very accurate movement control, repeatable positioning, and reliable communication regardless of the amount of vibration, temperature modulation, or continuous use cycles that may occur within the production environment.
