Absolute Rotary Encoder CEV58M-ETC P
Industrial Ethernet is a widely accepted standard for automation technology. The networking of devices familiar from the traditional field buses have also been established for new, Ethernet-based interfaces; the bus cable is connected from one device to another. Together with the voltage supply, each node has 3 connector cables. The EtherCAT P system provides real single cable solution for signal and supply of the encoder. The rotary encoder is supplied with voltage by suitable distributors, e.g. from Beckhoff, directly via the data cable. A star distribution topology is used for this purpose, i.e. each remotely supplied node has its own cable to the distributor node. If star wiring is advantageous for a specific system configuration, the wiring requirement can also be reduced to one line per rotary encoder through Power over EtherCAT-P. On each line, a maximum of 3A is available for sensor supply, so a single-cable (daisy-chain) structure becomes possible.
The rotary encoder has a specially coded M8 connector which can easily withstand the typical rigors of everyday industrial use. Incorrect connections are avoided by these exclusively coded connectors. Specific cables with molded plugs are a perfect solution for applications with compact-machines. The M8 plugs fit into very narrow grommets allowing for a small overall cable profile.
Rotary encoders with EtherCAT P for control technology are absolutely compatible with rotary encoders for series cabling. With an industry-standard resolution of 8192 steps per revolution and 4096 resolved revolutions, the rotary encoders in series CEx58 acquire all rotary and linear travel information of a machine with reliable and repeatable accuracy. Signal processing is fast enough so that together with the EtherCAT network designed for dynamic drive systems, position control with a CE_58 ETC encoder is easily achieved.
