New Servo Cables Withstand High Accelerations

As machine tools get faster and faster, there’s a growing need for high-acceleration servo systems. These servo systems obviously require more robust motors and mechanical components. What’s less obvious is that they also need power and signal cables that have been designed to withstand acceleration-related stresses.


At the IMTS Show next month (Booth E–4624), we’ll have Lapp technical experts on hand to discuss the effects of high acceleration motion on cable lifecycle and performance. We’ll also be showcasing our brand new lineup of high-acceleration servo cables, including ÖLFLEX® SERVO FD 796 CP.

This high-acceleration cable’s features include extra-fine Class 6 copper stranding, polypropylene insulation, non-woven wrapping, tinned copper braiding and a polyurethane jacketing. The cable optionally contains either one or two control pairs.


The new cable supports accelerations in excess of 5g and travel speeds up to 5 m/sec. Travel distances can range up to 100 m. Intended for flexible applications, it has a minimum bend radius of 7.5 x OD.

Other than its outstanding ability to withstand high accelerations, FD 796 CP behaves much like any other high-performance servo cable. It resists oil and flame to UL standards. Temperature range for flexible applications is –40 to 80ºC.
