Selection Table for Servo Motor Cables & VFD Cables
Choosing the right cable is essential for the safe and reliable operation of servo drives and frequency converters. To help you quickly find the best solution, we have summarized the key product features in two clear selection tables.
Servo cables: The table includes different cable types such as motor connection cables as well as encoder and feedback cables for precise signal and power transmission. Important selection criteria include the required voltage rating, flame resistance, available UL/CSA approvals, and oil and chemical resistance. In addition, low-capacitance designs ensure high EMC safety and enable reliable servo drive operation even over long cable lengths.
VFD cables: The second table presents our range of VFD and UL motor connection cables, specially developed for use with variable frequency drives. Key selection parameters include flame resistance according to UL 1277 (Power and Control Tray Cable) / FT4, cULus and WTTC approvals, RHW-2, the IEEE 1202 (Vertical Flame Test), exposed run approval, direct burial suitability, the cold bend test, and verified moisture resistance – ensuring safe performance even under demanding industrial and outdoor conditions.
The product links in the tables take you directly to further technical details. As an experienced cable manufacturer, we also design customized servo hybrid cables according to your specifications, which are perfectly matched to your application.
