The UDMMC is a line of compact EtherCAT modules of two and four universal drives with rating of 12 to 80Vdc and 2.5A (5A peak) to 20A (40A peak) per drive. Each drive is programmable to control a 3 & 2 phase servo motor, a DC brush motor, a voice coil motor and a 2 & 3 phase step motor.
The UDMMC addresses the needs of demanding multi-axis motion applications with limited space, such as waferhandling robots, wire bonders, die bonders, electronics packaging, small manipulators, and table-top motion stages. With the optional powerful ServoBoostTMalgorithm (ordered with the controller), demanding positioning systems can achieve ultimate performance levels, such as speeds of meters per seconds and Nanometers of jitter, minimal settling time, and uncompromising system robustness with minimal sensitivity to disturbances and changes. Optional Safe Torque Off (STO) cuts the power to the motor without removal of the power source for applications that are required to comply with SIL-3 and PLe safety levels. The UDMMC is a slave that runs under any ACS’ EtherCAT masters. The 4-axis UDMMC can be ordered with mixed current specifications. See Ordering Options.
A comprehensive set of software support tools are provided for configuration, setup, tuning and diagnostics.
