► ABSOLUTE ENCODERS WITH FIELDBUS INTERFACE |MEM620-BUS i Square flange 63.5x63.5 mm Round flange 0 58 mm Round flange 0 58 mm Blind hollow shaft for motor coupling Blind hollow shaft, fixing by elastic support ► EtherCAT COMMUNICATION PROTOCOL Based on the industrial Ethernet communication protocol, the EtherCAT® interface is steady, flexible and fast, therefore particularly suitable for communication between control systems and peripheral devices, such as I/O systems, drives, sensors and actuators. MEM-BUS EtherCAT® encoders offer: • Real Time communication • Flexible number of nodes • Easy installation and maintainance • Net topologies configuration • Automatic slaves addressing • Flexible work ranges progamming EtherCAT^ Conformance tested ► ELECTRICAL & OPERATING SPECIFICATIONS MEM540-BUS_ECT_M_6 |mEM-BUS EtherCAT ENCODER PROFILE j • Ref IEC61158-1-6 & IEC61784-2 • Device Profile CANopen over EtherCAT (CoE), CiA DS-406 • Physical Layer: EtherCAT 100Base-TX, Fast Ethernet, ISO/IEC 8802-3 • Output code: Binary • Cycle time > 1 ms • Transmission rate 100 Mbit/s • Transmission: CAT-5 cable, shielded (STP), ISO/IEC 11801 Connectors IN and OUT SUPPLY CONNECTOR M12 female type, D code M12 male type, A code • Counting direction • Preset value • Measuring steps per revolution • Speed resolution • Total measuring length in steps MEM-BUS EtherCAT supports different operating modes: • Free-Run: The slave application is not synchronized to EtherCAT. The local cycle is started by the local timer interrupt of the application controller. The cycle time can be modified by the Master, but this is a local cycle and it does not depend on communication and on Master cycle. • SM3 Event: The slave application is synchronized to the SM3 Event (that is the cyclic inputs transmission to the Master). SM events are based on the time an EtherCAT frame is received. This time can jitter in the range of a few microseconds due to the EtherCAT Master implementation (delay in stack, PHY & MAC delay, etc.). • DC: The slave application is synchronized to the SYNC0 event, which is based on the Distributed Clocks Unit (DC). The jitter can be reduced to a few nanoseconds. • The DC mode grants high real-time performances * Elap reserves the right
