LAPP OLFLEX SERVO FD 796 CP Servo Cable Review: Specs, Price and Applications
Updated: 4 days ago
ÖLFLEX SERVO FD 796 CP is LAPP’s shielded PUR servo cable for continuously moving machine parts and cable chains. The current catalog offers multiple power and control conductor arrangements. A real part example, 0027977, is 4G50+2x(2x2.5) at U0/U 0.6/1 kV; it is not the geometry of every cable in the family.
Quick Verdict
Consider this family for a drive-to-motor cable chain with a defined dynamic route and electrical duty. Confirm the exact article’s bend radius, operating conditions and terminations. A cable-chain performance claim is not automatically a robot-torsion qualification.

Design and Engineering Assessment
Choose conductor size from the actual drive/motor circuit and installation. A larger power cross-section also changes cable diameter, bend requirements and moving mass. Do not treat electrical and mechanical selection as independent decisions.
Long motor links introduce electrical questions beyond simple conductor resistance. Match the drive’s permitted cable length, insulation requirements and any needed filtering or termination arrangements. The family’s long-travel claim is not a blanket drive-to-motor compatibility approval.
The shield and any screened control conductors have different jobs. Identify brake, temperature or other control functions correctly, and follow the actual connector pinout. A control pair must not be relabeled as an arbitrary feedback or industrial-network link.
Validate the Cable Chain
Confirm the selected cable diameter, minimum radius, chain fill, travel and acceleration. Use LAPP’s actual usage table and assembly guidance rather than combining independent headline maxima.
Provide strain relief and avoid unintended twist. A linear cable chain may experience a completely different fatigue pattern from an articulated robot dress pack.
Commission the Drive Link
Verify continuity, protective conductor and screen termination, then test representative loaded motion and warm duty. Check for interference at the actual machine’s sensors and communications.
Retain article number, cut length, glands/connectors and wiring details. Replacing the conductor arrangement or cable diameter can affect both electrical compatibility and chain mechanics.
Applications and Selection
High-cycle servo cable-chain installations with a defined article, drive/motor link and mechanical route.
For LAPP OLFLEX SERVO FD 796 CP Servo Cable, define the actual machine duty before selecting an ordering configuration. Include the required operating point, available installation space, environment and control interfaces. The specification table describes the product or family; the surrounding machine determines which of those features matters for the intended job.
Price and Value
Request a quote for the actual article and cut length, plus screen-compatible connectors, glands and preassembly where needed. The current catalog requires registration for individual price and stock inquiry; no public numeric offer is assumed.
Compare installed electrical compatibility and motion life at the same route conditions. Cable diameter, chain loading, assembly labor and replacement access all affect the useful cost.
Pros and Cons
Advantages
Dedicated shielded continuously flexing servo family
Multiple power/control conductor configurations
PUR construction for demanding machine environments
Limitations
Article-specific diameter and usage conditions govern
Cable-chain rating is not universal torsion approval
Long links need drive-system electrical validation
Who Should Consider LAPP OLFLEX SERVO FD 796 CP Servo Cable?
Consider LAPP OLFLEX SERVO FD 796 CP Servo Cable for high-cycle servo cable-chain installations with a defined article, drive/motor link and mechanical route. Establish the required operating point and installation interfaces before choosing the configuration, and use a representative loaded cycle as the acceptance basis.
LAPP OLFLEX SERVO FD 796 CP Servo Cable FAQ
Is every FD 796 CP the same conductor arrangement?
No. The family includes several power sizes and optional control pairs or triples.
What does article 0027977 identify?
The cited current part is 4G50+2x(2x2.5), not a generic family-wide construction.
Can all headline motion maxima be combined?
Only use the selected article’s qualified operating and bending-cycle conditions.
Does cable-chain suitability establish robot-torsion life?
No. The mechanical duty is different and must be separately qualified.
Can any control pair carry an encoder signal?
No. Match the actual interface, shielding and connector requirements.
Does a long travel claim approve every drive cable length?
No. The drive/motor electrical installation must also permit the link.
What should be checked after assembly?
Conductor identity, protective conductor, screen, terminations and loaded machine behavior.
What belongs in a quote?
Article number, length, motion duty, termination hardware and any preassembly/testing scope.
Prices are indicative and may change. Confirm the final configuration, commercial terms and delivery schedule before ordering.
