The MC-41103400 supports both synchronous and asynchronous motors, delivering vector control with ±0.1% speed accuracy 3. Its SERCOS III interface enables real-time communication with high-resolution encoders (e.g., HEIDENHAIN Endat 2.2), achieving sub-micron positioning in applications like semiconductor wafer handling. For example, in a solar panel manufacturing line, this drive ensures precise alignment of robotic arms with ±0.02 mm repeatability
