Servo motor terminals with OCT and STO input
The servo-motor EtherCAT terminals EL7201-901x (50 V , 2.8 A ), EL7211-901x (50 V , 4.5 A ) and
DC rms DC rms
EL7221-901x (50 V , 7...8 A ) with integrated absolute value interface, offer high servo performance in a
DC rms
very compact design. The EL72x1-901x were designed for the motor types of the AM81xx series from
Beckhoff Automation.
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.
