Function
The
ASD-A2-0721-U is the high-performance controller for the 750W motor, specializing in: [
1]
- High-Power Regulation: Converts 220V AC (Single or 3-Phase) into precise current for the larger 750W motor coil requirements.
- Smart Motion (E-CAM): Built-in Electronic Cam functionality allowing for complex path following without the need for an external motion controller.
- Network Integration: The "U" suffix indicates advanced digital communication capabilities, supporting high-speed command execution and integration into industrial fieldbus networks.
- Stability Control: Features Vibration Suppression and Full-Closed Loop support (via an external linear scale) to eliminate mechanical backlash. [1, 2, 3, 4, 5]
