Compatibility with the leading drive systems from SIEMENS, Rockwell, Lenze or SEW
Our assembled servo cables are true-to-original and therefore 1:1 compatible assembly solutions for the common drive systems from the major manufacturers SIEMENS, Rockwell Automation, Lenze and SEW-EURODRIVE.
Each manufacturer of servo drives has developed its own technical standards, which must be taken into account when selecting cables and connectors. The selection of suitable connection components for servo drives can therefore quickly become a challenge. But with the assembled servo cables from LAPP, this effort is a thing of the past.
We take care of the compatibility check for you: we carefully harmonise our products with the manufacturer's specifications right from the development phase. This includes connectors, cable lengths, cross-sections, shielding, electromagnetic compatibility (EMC) and mechanical and thermal load capacity.
The result: fully ready-to-connect cables that precisely match the interfaces and requirements of the leading drive manufacturers.
Your advantages when using standard-compliant servo assemblies:
Fast commissioning
No need to search for suitable plugs and cross-sections - LAPP delivers plug & play.
Safety and longevity
Compliance with parameters such as EMC, impedance, interfaces etc. guarantees interference-free communication.
Future-proof
Thanks to the consistent focus on manufacturer specifications, our solution remains updateable and expandable (e.g. with TIA Portal)
LAPP as a system partner
LAPP thinks in holistic solutions, not in individual parts. Our many years of experience in component manufacturing have given us extensive technical expertise and an excellent knowledge of the industry. We are a competent and reliable system provider.
Several hundred servo assemblies for almost any application
Whether standard or special application: With several hundred tested variants and cable cross-sections of up to 4 mm2, LAPP also offers a customised solution for your application. If you cannot find what you are looking for, customised solutions are also available on request.
European production & global availability
LAPP produces in state-of-the-art factories in Europe and operates a global sales and logistics network. This means you benefit from short delivery times and local expertise and support - worldwide.
Optimised connectors with 360° EMC protection
Our connectors ensure continuous, reliable shielding - with 360° EMC shielding for maximum interference immunity. Ideal for dynamic, demanding industrial environments.
Available cable types
With the servo assemblies from LAPP, both cable ends are always prepared for the servo connection (using connectors, end sleeves, cable lugs or similar). The assemblies are suitable for drive systems from SIEMENS, Rockwell Automation, Lenze or SEW-EURODRIVE.
Power supply to the servo motor. 6- to 9-core (depending on drive manufacturer), for 0.6/1 kV nominal voltage.
for signal transmission from the servo motor's feedback system to the frequency converter. Multi-core, for extra-low voltage, also known as (rotary) encoder cables.
for simultaneous power supply as well as signal and data transmission. Space and weight saving, for reduced cable and connector insert.
Individual customer requests regarding printing, labelling and packaging can be sent to us separately at any time.
What is important for your application?
The LAPP servo assemblies essentially differ in terms of the sheath material and the connector used. The available cable assemblies are configurable in length (from 0.5 m to 100 m).
Which jacket material should I choose?
Decide which material should protect your cable – taking into account the location of subsequent use and the expected mechanical and chemical loads there.
Depending on the intended use, there are major differences in the cable design and the materials used. Our cable assemblies are designed for different types of installation:
- Fixed or occasional flexing use
- Highly flexible use in cable chains
- Torsion application in the robot
- Suitable for permanent installation and occasional movement without tensile stress.
- Resistant to acids and alkalis, and oil-resistant to a limited degree.
- Can be used in dry and damp spaces.
- Suitable for highly flexible, continuous use in moving machine parts and in cable chains.
- Withstand high mechanical loads.
- Are resistant to mineral oil-based lubricants and are often chemically resistant.
- Can be used in dry, damp and, in particular, harsh and oily environments.
Which connector is the right one?
The connectors for servo applications must be as small as possible, vibration-proof, robust, EMC-protected and also resistant to moisture, oils and dust. Circular connectors have become established for connecting a servo motor or its feedback system, particularly the M12, M17, M23, LS1, LS1.5, LS3 and V4.0 families.
- Nickel-plated connector housing or plastic-coated connector housing
- When plugged in, protection class IP 66/67 can be achieved.
- Can be used at -20 °C to 130 °C
Provides improved protection against electromagnetic interference: The cable shield is crimped with two metallic sleeves, enabling 360° contact to be achieved. This ensures even more effective deflection of interference signals.
- Tamper-proof locking thanks to automated pressing process
- Plastic-coated connector housing
- When plugged in, protection class IP 67 can be achieved.
- Can be used at -20 °C to 90 °C
Key information
Servo drives are considered indispensable in modern automation technology. They work with absolute precision as they can be controlled, adjusted and positioned.
What are the components of a servo drive?
- A servo controller and
- a servomotor.
They are operated in a permanent control loop.

Servo motors are special electric motors (which can be direct current, asynchronous or synchronous motors) in which the exact angular position of the rotor, its rotation speed and acceleration can be determined using an integrated feedback system. The respective actual values are transmitted to an electronic control system, the servo controller. As a rule, frequency converters with motor position control take on this task. If the actual state of the servo motor differs from the target state, the frequency converter can adjust the output frequency or voltage and thus the torque and speed for the servo motor.
Servo drives can be found in all areas of automation, for example in mechanical engineering, energy technology, the automotive industry, conveyor technology, robotics and the food & beverage sector.
For one thing, they impress with their compact design and low weight. Above all, however, servo drives reduce process times and massively increase the efficiency of a plant.

Servo cables connect the servo motor and its feedback system to the upstream frequency converter within a servo application.
Servo applications are all applications that are controlled by an electrical, frequency-regulated servo drive.
Assembled servo cables are ready-to-connect servo cables where both ends have already been prepared for connection - i.e. connectors, end sleeves and cable lugs are already attached. For you as the end user, there is no need to strip the cable, crimp contacts or install the connector. The advantage lies clearly in the combination of time savings, safety, quality and process simplification. The servo assemblies from LAPP can be used immediately.
No matter what conditions you have: We will customise your servo cable so that it meets your specifications and the current industry standards. Simply specify the drive standard, the type information and the required line length. You will then receive all the information on the original assembly or the LAPP alternative according to the selected standard.
- through precise control and positioning of the devices and machines to be controlled,
- through high repeat accuracy in the processes,
- through high acceleration and deceleration of the executed movements.
- The positioning axes of a beverage bottling system work with millimetre accuracy thanks to rotor position sensors. The individual process steps are carefully coordinated so that the liquid ends up in the bottle rather than next to it. Even after a million repetitions.
- Perfection in the workpiece processing of CNC machines that, for example, laser, mill, turn or grind (and do so with precise acceleration and braking) would be unthinkable without highly dynamic axial control.
- Assembly, sorting and painting robots too are only able to do such a masterful job owing to precisely controllable and adjustable servo drives.
- Even in theatre and stage technology, set motion sequences are controlled using a servo drive. Then it's time to say, ‘Curtains up for...!’
