EtherCAT servo terminals

The EL7221-9014 servomotor EtherCAT Terminal with integrated One Cable Technology (OCT) offers powerful servo performance in a very compact design for motors from the AM8100 series up to 8 A (Irms). OCT combines a motor cable and an absolute feedback system in a single cable. The integrated electronic type plate of the AM81xx motors can be read in by the servo terminal to configure the motor parameters automatically. Thus, commissioning of the motors as well as cabling are minimized. The high-performance control technology supports fast and highly dynamic positioning tasks. Monitoring of numerous integrated parameters offers maximum operational reliability. The specified output power is attained in operation with the ZB8610 fan cartridge. For operation without a fan cartridge, the EL7211-9014 is recommended. The STO function according to EN 61800-5-2, can be implemented using the reaction-free HWE input corresponding to a safety level Cat. 3, PL d according to DIN EN ISO 13849-1:2015 (see document "EP7211-0034 | TwinSAFE application example").
