EP7211-9034 | Servomotor module with OCT and STO, 50 V DC, 4.5 A (Irms)

The EP7211-9034 servomotor EtherCAT Box with integrated One Cable Technology (OCT) offers high servo performance in a very compact design for AM8100 series motors with up to 4.5 A (Irms). The One Cable Technology combines motor cable and absolute feedback system in a single cable. The integrated electronic type plate of the AM81xx motors can be read in automatically by the servo box to configure the motor parameters. In this way, wiring and commissioning requirements are minimised.

The high-performance control technology supports fast and highly dynamic positioning tasks, while numerous monitoring functions offer maximum operational reliability. EtherCAT as a high-performance system communication enables ideal interfacing with PC-based control technology. LEDs indicate status, warning and error messages as well as possibly active limitations. Two integrated digital inputs enable the connection of limit switches. The EP7211-9034 enables the user to implement STO safety functions (Safe Torque Off) corresponding to a Cat 3, PL d safety level according to EN ISO 13849-1:2015.
