Programmable encoders for EtherNet/IP applications
Published: 12 March 2012 - Neil Mead
Sick UK is launching a range of EtherNet/IP-compatible programmable absolute encoders. The new Ethernet/IP AFS60 single-turn and AFM60 multi-turn encoders offer diagnostic and monitoring capabilities for improved plant reliability and availability.
Designed for both precision applications and harsh industrial conditions, the new Sick EtherNet/IP encoders are the first to integrate DLR (Device Level Ring) technology for continuous monitoring of network integrity. Network communications can be rebuilt seamlessly in the event of a cable break preventing downtime. Furthermore, the position of the break is reported, enabling remedial action to be taken quickly and efficiently at the next convenient opportunity.
The round loop capability of the AFM60 EtherNet/IP multi-turn encoder cuts programming and hardware costs for machine builders. Its rotary axis function enables the number of encoded rotations to be defined as a fraction, an important function for rotary applications such as turntables or power presses which often have gearing between the encoder and rotating axis. This saves complicated PLC calculations and control programming, and so cuts costs during installation, maintenance and service.
EtherCAT and ProfiNET variants will be added to Sick’s AFM60 and AFS60 family of encoders during the coming months.
