One Servo Cable Covers All The Bases

All servo cables are the same, right? Well, not really. There are thousands of different servo cable types, each with its own electrical and mechanical capabilities and set of approvals. If you build, install or maintain industrial machines, the sheer diversity of servo cables can be a real problem.

To meet all your application requirements, you end specifying and stocking many types of servo cables, which drives cost and complexity. Our latest servo cable can help you simplify your selection process.

Designed for stationary applications with occasional flex cycles the ÖLFLEX® SERVO 719 CY is the closest thing you'll find to a universal servo cable. It offers a broad range of sizes, electrical properties and approvals. It also features new construction that allows the cable to span longer installation lengths.

Here's a closer look at all the SERVO 719 CY cables can do:

Sized And Built Right. SERVO 719 CY comes in more than 20 sizes to meet the requirements of different servo drive systems. The new cable also offers a thinner outer diameter than comparable UL-certified cables, saving additional space and weight.

The cable consists of four conductors for motor power and protective ground, plus one or two optional control pairs. SERVO 719 CY cables have a copper shielding, polypropylene insulation and PVC jacketing.

Enhanced Electrical Properties. To meet the requirements of a common motor-and-drive systems, SERVO 719 CY has a UL nominal voltage of 1,000V and test voltage of 4,000 V.  

The new cable also features other key electrical property enhancements that allow longer cable runs. To make the longer runs possible, the cable insulation has been optimized to reduce capacitance and leakage currents while improving dielectric strength.

Multiple Standards. Because it supports multiple regulatory standards, SERVO 719 CY can serve in many different stationary industrial machines and automation systems. These approvals include:

•     UL AWM Style 2570
•     Flame Retardant VW-1
•     cRU AWM I/II A/B FT1
•     CE
•     RoHS

With its mix of properties and approvals ÖLFLEX SERVO 719 CY can serve as a drop-in-replacement for our ÖLFLEX SERVO 700 CY and ÖLFLEX SERVO 709 CY cables. 

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.
