Beckhoff is extending its range of compact drive technology even further in the higher performance segment with the development of the EL7051 EtherCAT stepper motor terminal. Stepper motors up to 8A at a rated voltage of 80V DC can be directly connected to the EL7051 EtherCAT Terminal. Therefore, it is also possible to drive stepper motors with a higher power rating directly from the I/O system. In combination with the AS1060 stepper motor from Beckhoff, the EL7051 represents an inexpensive small drive solution.
As an addition to the existing EL7031 and EL7041 stepper motor terminals, intended for motors up to 24V DC and 1.5A or 50V DC and 5A respectively, the new EL7051 is suitable as a complete drive system for motors up to 80V DC and 8A. The terminal contains both the outputs for the motor and the inputs for the feedback system. Feedback systems can be eliminated in simple applications, since the terminal has an internal counter.
The pulse-width modulation (PWM) output stages of the EL7051 EtherCAT stepper motor terminal cover a wide voltage and current range. Together with two inputs for limit switches, they are located in the terminal. By setting a few parameters in the object directory, the EL7051 can be adapted to the motor and the application, e.g. via the TwinCAT System Manager. The 64-fold micro-stepping ensures particularly quiet and precise motor operation. Together with the AS1060 stepper motor, the EL7051 represents a complete, compact motion axis. Preferred fields of application for the inexpensive drive solution include, for example, feed axes or simple transport and stroke movements.
