Servo motors are the heartbeat of modern automation, driving precision, performance, and productivity across industries—from robotics and packaging to machine tools and logistics. However, the success of any servo system heavily depends on the quality and compatibility of the cables that connect these high-performance motors to their drives. Selecting the right cable isn’t just a technical requirement—it’s a strategic choice that can impact system efficiency, longevity, and safety.
Enter LAPP, a global leader in cable technology. Known for their innovation, durability, and tailor-made solutions, LAPP provides a comprehensive range of servo cables designed to meet the most demanding requirements of today’s servo motor applications. Whether you’re looking for robust resistance to oil, flexible motion capabilities, or superior electromagnetic compatibility (EMC), LAPP has a solution that fits perfectly.
Why Cable Selection Matters in Servo Systems
Servo systems are unique. Unlike conventional motors, they rely on feedback mechanisms for precise control of speed, position, and torque. This demands not only power transmission, but also signal integrity and EMC protection—all within a single, compact system. Poor cable quality can lead to:
- Signal loss or delay
- Unwanted interference
- Premature cable failure
- Increased downtime
That’s why using a high-quality cable that’s matched to the motor’s demands and the installation environment is critical.
LAPP’s Cable Solutions: Engineered for Every Scenario
LAPP has designed an extensive portfolio of servo motor cables to meet diverse industrial needs. Here’s how their solutions align with different servo motor requirements:
1. ÖLFLEX® SERVO 719 and 728 Series – Standard Performance, Exceptional Quality
For standard servo applications in dry or slightly oily environments, the ÖLFLEX® SERVO 719 and 728 cables are ideal. They offer:
- Flame-retardant PVC outer sheath
- Fixed installation or limited flexing use
- EMC optimized with overall copper braid shielding
- Compatibility with popular servo systems like Siemens, Lenze, SEW-EURODRIVE
These cables deliver solid performance at an excellent price-performance ratio, making them suitable for standard drives in packaging machines, conveyor systems, or woodworking machinery.
2. ÖLFLEX® SERVO 7TCE – For Harsh Industrial Environments
When durability is paramount, the ÖLFLEX® SERVO 7TCE stands out. These are TC-ER (Tray Cable – Exposed Run) approved, UL-listed cables suitable for demanding applications:
- Resistant to oils, UV, and mechanical stress
- Can be installed in cable trays without conduit
- Ideal for applications in automotive manufacturing, steel plants, and processing industries
Its robustness reduces the need for additional cable protection, helping simplify installation while ensuring long-lasting performance.
3. ÖLFLEX® SERVO FD – Built for Continuous Flexing
For dynamic servo applications such as robotics, automation arms, or pick-and-place systems, where the cable undergoes constant bending and motion, the ÖLFLEX® SERVO FD family is the go-to option:
- Designed for continuous flex in cable tracks
- High torsion resistance for 3D movement
- Long service life even under extreme stress
- Superior EMC shielding
These cables ensure stable power and signal transmission even under millions of motion cycles—minimizing the risk of unexpected downtime.
4. Hybrid Servo Cables – Power + Signal in One
Modern servo systems often benefit from hybrid cables—which combine power conductors and encoder/sensor pairs in a single sheath. LAPP offers ÖLFLEX® SERVO FD hybrid variants designed to:
- Reduce cabling complexity
- Save space in compact machines
- Simplify cable management
- Enhance overall efficiency
Hybrid cables are especially useful in servo drives of CNC machines, modular equipment, and compact automated production lines.
Global Certifications and Easy Integration
One of the standout features of LAPP cables is their global compatibility. Most servo cables come with:
- UL/CSA, CE, and RoHS certifications
- Compatibility with leading drive systems (Siemens, Bosch Rexroth, Fanuc, etc.)
- Proven compliance with international safety and EMC standards
This ensures seamless integration and approval, whether you’re operating in North America, Europe, or Asia.
Sustainability and Reliability: A Long-Term Partnership
LAPP isn’t just about quality cables—they’re about long-term solutions. Their cables are halogen-free, recyclable, and designed for extended life cycles. This makes them an excellent fit for companies focused on sustainability, total cost of ownership, and maintenance reduction.
The Bottom Line: Find the Perfect Match
In the complex world of servo motors, not all cables are created equal. Choosing the right cable solution can be the difference between smooth operations and costly downtime. LAPP offers an unmatched range of servo motor cables that can be precisely tailored to your application—whether it’s a static machine in a warehouse or a high-speed robotic arm in a factory.
