maxon’s EPOS3 70/10 EtherCAT easily integrates as slave into real-time EtherCAT protocol-based Ethernet networks. A multitude of operating modes allows efficient, flexible use in a wide range of drive systems in robotics, automation, and mechatronics. The positioning controller supports a broad bandwidth of encoders.

In the typical EtherCAT, the EtherCAT master calculates the trajectory points and sends the target parameters cyclically and synchronous via EtherCAT network to the EPOS3. The corresponding control loops for position, speed, and torque/current take place in the EPOS3 and then delivers the measured actual values (position, speed, current) to the EtherCAT master.

For the actual drive control, the EPOS3 70/10 EtherCAT is equipped with superb motion control functionality.

Additional features include speed control with given target velocity to a defined mechanical position using numerous implemented methods is available. The same applies for the generous number of inputs and outputs, which makes the extra EtherCAT I/O module obsolete. Digital inputs/outputs (11/5) can be configured as reference or limit switch as well as Capture or Trigger, or can be used to activate holding brakes with definable ON/OFF switching delays. Additionally, analog inputs/outputs (2/1) are at free disposal. Tailored for servo motors, the EPOS3 70/10 EtherCAT offers built-in motor filters with motor chokes for EMC-conform operation.

The controller offers comprehensive circuitry against overcurrent, excess temperature, undervoltage and overvoltage, voltage transients, and short-circuits in the motor cable. Furthermore, it is equipped with adjustable current limitation to protect motor and load as well as protected digital inputs and outputs.
