ÖLFLEX® SERVO FD 7DSL
Low capacitive hybrid servo cable with PUR sheath for highly dynamic power chain application – certified
ÖLFLEX® SERVO FD 7DSL – hybrid cable for permanently flexing applications with UL/cUL AWM.
- OCS – One Cable Solution
- Suitable for Hiperface DSL® motor-feedback systems
- Extended line for high loads in power chains
Benefits
- Allows much faster motion sequences which increases the economic efficiency of machines
- Only one connection line between frequency converter and motor-feedback system. Instead of the encoder cable, an integrated DSL pair takes over the signalling.
- Fewer cables required and reduced connection costs
- Space and weight savings thanks to hybrid cable design
- Durable under harsh conditions thanks to robust PUR sheath material
- Resistant to contact with many mineral oil-based lubricants, diluted acids, aqueous alkaline solutions and other chemical media
Application range
- Applications in electric drive systems
- Connecting cable between servo controller and motor
- In power chains or mobile machine parts
- For use in assembly & automatic placement machines
- Particularly in wet areas of machine tools and transfer lines
