Function
The ASD-A2-1021-U is the command center for the 1.0 kW system, featuring:
- High-Power Conversion: Specifically tuned to drive the 1000W motor using 220V AC (Single or 3-Phase) input.
- Advanced Motion (E-CAM): Built-in Electronic Cam logic for complex, synchronized movements without requiring an expensive external motion controller.
- "U" Series Connectivity: Supports high-speed digital communication and extended I/O, allowing it to integrate seamlessly into modern industrial networks (RS-485/Modbus).
- Safety & Precision: Includes Safe Torque Off (STO) for emergency stopping and vibration suppression algorithms to keep high-torque movements smooth and silent. [1, 2, 3, 4, 5]
