Igus has developed a robust and reliable single-cable system for servo motors. With an integrated bus element, the Chainflex CF270.UL.D hybrid servo cable is, the company says, ideally placed to meet the increasing demand for single hybrid cable technology in the drive manufacturing industry.

Hybrid servo cable

Whereas in the past, servo motors and converters were generally connected with two cables — one servo cable for the motor’s energy supply and an encoder cable for data feedback — more drive manufacturers are now offering servo motors with single-cable technology.

This means that energy supply as well as data feedback are operated by a single cable, with complex measuring system cables being replaced by bus technology.

According to the company, the main advantage the Igus Chainflex CF270.UL.D hybrid servo technology has over ‘standard’ servo cabling is its space-saving function. In addition, the number of plugs and therefore the costs for additional material and installation are reduced.

Also, thanks to its bending-resistant shield made of tinned copper wires with an optical covering of 80 per cent, the sensitive bus signal pairs are effectively protected from disturbances and overall electromagnetic compatibility (EMC) of the cable is ensured.

Key product features

  • Space saving
  • Bending-resistant shield protects sensitive bus signal pairs
  • Specifically designed for use in energy chains
  • Guaranteed for millions of cycles at a bend radius of just 10x cable diameter  
  • UL, CSA and NFPA79.2012 certified
  • Oil resistant, flame retardant and halogen free
  • Due to its Desina conforming orange outer jacket, it is able to endure excessive load conditions, meeting the stringent requirements of machining centres and machine tools
  • Its properties also make it ideal for conveyor technology, as well as in low-temperature applications

Igus

Igus is the largest producer of reinforced plastic energy chains and injection-moulded polymer bearings. The range of polymer bearings includes Iglidur plain, Igubal spherical and Drylin linear bearings. They offer an excellent price-to-life relationship and are developed under the toughest conditions. They are oil, maintenance and lubrication free, low wear, resistant to dirt and dust, corrosion free and simple to fit. Igus also has the data to precisely predict the lifetime of these bearings within a specific application.

Energy chains are the umbilical cord of modern machines. They minimise downtime and protect, support and extend the service life of cables and hoses. The broad range incorporates more than 30,000 innovative, low-cost products. From the smallest ‘micro’ chain to the largest chain in the world, the E4.350, Igus energy chains are capable of long and short travel distances at high speeds in all axes.

Igus also has its own cable series, Chainflex, specially designed with energy chains in mind. They are highly flexible cables, offering a long service life and very small bending radii. A wide range is available, from small signal cables to large power cables, high-speed data cables and glass fibre-optic cables.

The company’s energy chains and Chainlflex cables can be delivered as a fully harnessed and pre-assembled Readychain system, cutting purchasing, warehousing and installation costs.
