March 20, 2013 - HELUKABEL announced TOPSERV Hybrid PVC and Hybrid PUR cables. These 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 cables combine the existing structure of power conductors and break pairs with an encoder cable element. The encoder element serves as the central communication interface between the frequency 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. By adding the encoder cable element to the existing servo power cable structure, the single cable becomes slightly thicker. However, the cable’s mechanical and electrical properties remain the same, which prevents the disruption of data or power transmission caused by any electromagnetic interference or ‘cross talk.’ Given that this encoder technology is still relatively new, the TOPSERV Hybrid PVC and TOPSERV Hybrid PUR cables will be produced to meet each customer’s specific set of operating criteria, such as the drive manufacturer chosen, fixed or flexing application, country-specific approvals, etc. Combining both the power and data transmission elements into one cable allows HELUKABEL to minimize the amount of cabling used, which reduces installation/maintenance time and lowers the overall costs for machine end-users, OEM machine builders, and drive system manufacturers. 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.
