Courtesy: HelukabelHelukabel's Topserv Hybrid PVC and Topserv Hybrid PUR cables allow machine end-users, OEM machine builders, and drive system manufacturers to combine the existing power and feedback cables into a single cable in order to connect the frequency inverter to the motor’s feedback system.

The Topserv Hybrid family contains four power conductors plus two additional pairs – one brake and one encoder. The cables are available in PVC or PUR outer jackets for flexible or high flex applications, respectively, and have been tested to withstand greater than five million cycles of alternating bending stress. The Topserv Hybrid cables are UL rated to carry up to 1000V of current. In addition, the cables are oil resistant, flame retardant, halogen free (LSZH), and are UL, CSA, CE, and RoHS approved.

Helukabel’s Topserv cables are also designed to combine the existing structure of power conductors and break pairs with an encoder cable element. Helukabel’s cable replaces one of the traditional brake pairs with an encoder cable. The encoder element serves as the central communication interface between thefrequency inverter and the motor-feedback system. The use of an encoder cable allows for enhanced transmission of motor position data and feedback, such as operating temperature.
