ECMsm Motion Controller with Servo Drives
2 or 4 Axis EtherCAT® Universal Drive Module

The UDMsm is a member of the Universal Drive Module (UDM) series of EtherCAT-based drives. It is designed to meet the needs of OEMs with demanding multi-axis motion control applications. Controllable by any ACS SPiiPlus Platform EtherCAT master, it leverages powerful servo control algorithms to maximize motion system performance. At the same time, its universal servo drive technology allows the system designer to control almost any type of motor or stage.
