Core Functions
- Motion Control Intelligence: Features a built-in Electronic Cam (E-CAM) with up to 720 points, allowing it to perform complex synchronized motions like flying shears or rotary cuts without an external motion controller.
- Precision Regulation: Uses a high-speed Digital Signal Processor (DSP) to deliver a frequency response of up to 1 kHz and settling times below 1ms, ensuring fast and stable machine operation.
- Flexible Control Modes: Supports Position, Speed, and Torque control modes, which can be easily switched to adapt to different automation tasks.
- Safety & Stability:
- Vibration Suppression: Built-in automatic filters minimize mechanical oscillations at the machine edges, ensuring smoother movements.
- Protection Mechanisms: Includes hardware safeguards against overcurrent, overvoltage, motor overheating, and encoder errors to prevent equipment damage.
- Network Integration: The "U" type specializes in digital communication via RS-485 and includes an extension port for digital inputs, making it ideal for distributed control in complex industrial networks.
The ASD-A2-0421-U is primarily rated as a
400W (0.4 kW) servo drive. While it is often paired with 400W motors, it is sometimes applied in systems described as 500W depending on the specific motor matching (such as medium-inertia ECMA-E series motors). [
