EtherCAT Master Motion Controller with up to 3 Integrated Servo Drives

The CMxa Control Module is designed to meet the needs of OEMs with demanding multi-axis motion control applications. Its unique multi-processor architecture leverages powerful profile generation and 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. As an EtherCAT master, it can control ACS products within the SPiiPlus Motion Control Platform and third-party EtherCAT products.
