EL7211-9014 | Servomotor terminal with OCT and STO, 50 V DC, 4.5 A (Irms)
The EL7211-9014 servomotor EtherCAT Terminal with integrated One Cable Technology (OCT) offers high servo performance in a very compact design for motors from the AM8100 up to 4.5 A (Irms). The One Cable Technology 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 automatically by the servo terminal to configure the motor parameters automatically. Thus, wiring and commissioning expenditure are minimised.
The fast control technology, based on field-orientated current and PI speed control, supports fast and highly dynamic positioning tasks. The monitoring of numerous parameters, such as overvoltage and undervoltage, overcurrent, terminal temperature or motor load via the calculation of a I²T model, offers maximum operational reliability. EtherCAT, as a high-performance system communication, and CAN-over-EtherCAT (CoE), as the application layer, enable ideal interfacing with PC-based control technology. The latest power semiconductors guarantee minimum power loss and enable feedback into the DC link when braking. 16 LEDs indicate status, warning and error messages as well as possibly active limitations.
The EL7211-9014 enables the user to implement the safety function STO (Safe Torque Off) that corresponds to a Cat 3, PL d safety level according to EN ISO 13849-1:2015.
