The UDMnt addresses the needs of demanding multi-axis motion applications with limited space, such as wafer-handling robots, wire bonders,
die bonders, electronics packaging, small manipulators, and table-top motion stages.

With the optional combination of a 5MHz laser encoder interface, the powerful ServoBoost and MotionBoost  algorithms, demanding positioning systems achieve ultimate performance levels, such as speeds above 1m/s with position jitter below 3nm, almost zero settling time, and uncompromised system robustness with minimal sensitivity to disturbances and changes.

The UDMnt is a slave that runs under any ACS EtherCAT masters. A comprehensive set of software support tools are provided for module
configuration, setup and tuning.
