Miniaturised EPOS2 controllers for the CANopen network

02 June 2011

maxon motor has introduced a compact positioning controller for controlling and commanding miniaturised applications in the CANopen network. Three variations of the EPOS2 24/2 are available, suitable for driving brushed dc and brushless EC motors up to 48W, with digital encoders and Hall sensors as required. Measuring just 50mmx40mm, the EPOS2 24/2 offers impressive control functionality, including dual loop position and speed controller.

Interpolated Position Mode (PVT) allows very accurate, synchronous running with high dynamics, and co-ordinated multiple-axle movements, while step/direction mode gives incrementally controlled movement of the motor shaft, and master encoder mode applies the drive as electronic gearing.

Moreover, as part of maxon’s second generation EPOS2 family, the controller’s compatibility with CANopen according to CiA 40, is supplemented with USB and RS232 communication, including the key gateway functions USB-to-CAN and RS232-to -CAN.

Backwards compatibility in both mechanical and electronic aspects also ensures the 24/2 has exactly the same dimensions and pin compatibility as its predecessor the EPOS 24/1, but with added functionality and double the output power.

Similarly, the easy-to-use EPOS Studio user interface enables engineers to transfer parameters from the 24/1 to the new 24/2 controller with ease – as well as fine-tuning its operation at will.

A wided variety of modes, including position, current and velocity control make the controller a flexible choice for automated systems, tools building and mechatronics, particularly where space is at a premium.
