The EtherCAT SubDevice ECAT-2074A is an absolute encoder master. ECAT-2074A provides four channels. Each channel is independent of each other. It supports two serial transmission interfaces: SSI (Serial Synchronous Interface) & BiSS-C (BiSS Continuous Mode, unidirectional). ECAT-2074A also supports a maximum transmission frequency of 10MHz, a maximum transmission bit of 48bit(Including error bit, warning bit, CRC in BiSS-C mode), and Automatic compensation of cable delays in BiSS-C mode. The maximum cable length supported is 70 meters.
