In high-performance automation, every power cable, feedback wire, and connection cable plays a vital role. Servo cables and accessories form the essential link between the servo drive, servo controller, and servo motor, ensuring accurate motion, stable power transmission, and reliable data feedback.
At Venus Automation, we supply a complete range of servo cables, shielded Ethernet cables, pre-assembled connectors, glands, and wiring accessories. Whether you need a single motor power wire, a servo drive control harness, or a complete harnessed cable set, our solutions are built to last in industrial environments across Australia.
Understanding Servo Cables and Their Role
Power Transmission and Feedback
A servo cable connects your servo drive or servo amplifier to the motor, carrying controlled voltage and current for precise torque control. Meanwhile, feedback and signal cables return encoder and resolver data to the servo controller, closing the loop in the servo drive control system.
Typical installations include:
- Power cables with high-quality copper conductors and TPE insulation for mechanical flexibility.
- Encoder or connection cables that transfer feedback signals between the motor and controller.
- Shielded Ethernet cables for digital communication between Centroid CNC control systems or industrial PLCs.
Together, these components ensure that your automation network maintains accuracy, stability, and noise immunity — even under heavy electrical loads.
Cable Construction and Materials
Conductors and Insulation
High-grade copper conductors with low resistance ensure minimal voltage drop across longer distances. To improve mechanical endurance, Venus cables use TPE mixtures and PUR sheaths that resist oils, UV, and continuous flexing.
Shielding and Grounding
In noisy electrical environments, shielding is critical. Our shielded servo cables feature foil and braid layers to block EMI, while ground wires and signal pins maintain stable reference potential across all axes. Proper grounding prevents data corruption and ensures safe operation of your servo drives and power supplies.
Servo Cable Accessories and Assembly Options
Pre-Harnessed Cables
Harnessed cables simplify installation by combining power, signal, and feedback wiring in one jacketed assembly. Each comes pre-terminated with industrial connectors and tested for continuity and insulation resistance before shipment.
Cable Glands, Ferrules, and Boots
For durability and ingress protection, cable glands seal motor and controller entry points. Cable ferrules ensure clean terminations within terminal blocks, while strain-relief boots protect against bending stress — extending the life of both cable and connector.
Interconnecting and Extension Cables
Venus Automation also provides specialized interconnecting cables, including Power Cable for 631 to ACG & ACM2n Motors and Interconnecting Cable for 631 to IBT HMI, ensuring compatibility across diverse OEM platforms like Bosch Rexroth, Schneider Electric, and Parker SSD Drives.
Power and Control Systems Integration
Servo Drive and Controller Synchronization
A servo drive delivers power to the motor, while the servo controller generates motion commands. Servo cables ensure these two devices exchange real-time feedback signals, enabling precise torque, velocity, and position control.
Whether you’re integrating Compax 3 Servo, Kinetix 3, or Lexium 32 systems, our servo drive control cables maintain synchronization between motor, drive, and encoder feedback.
Each power supply connection is engineered to handle continuous current loads with minimal temperature rise, while shielding prevents interference between analog feedback and digital communication lines.
Cable Management and Motion Performance
Dynamic machinery like knee mills, robot arms, or CNC routers requires flexible cabling capable of millions of bending cycles. Our drag-chain rated servo cables feature reinforced PUR jackets and stranded copper cores that resist torsion and abrasion.
Cable Routing Best Practices
- Maintain a defined bend radius to prevent conductor stress.
- Separate power wires from low-voltage signal cables.
- Use ferrite cores and advanced ferrite long-life brushes to suppress transient noise.
- When required, implement a harmonic drive coupling for smoother motion.
For maximum service life, use our CAD service life calculator to estimate flex durability based on machine configuration and movement frequency.
