About ASD-A2-1021-U* Delta A2 Series Driver - 1000W
The ASD-A2-1021-U is the high-performance 1000W (1.0 kW) AC servo drive from Deltas ASDA-A2 series. It is specifically designed to provide high-resolution control for motors like the ECMA-E11310RS.
Core Power & Electrical
- Rated Power: 1000 Watts (1.0 kW).
- Input Phase/Voltage: Single-phase or 3-phase, 200V ~ 230V AC (+10% / -15%), 50/60 Hz.
- Continuous Output Current: 7.3 Arms.
- Frequency Response: 1 kHz (for rapid command execution).
- Speed Control Range: 1:5000.
Control & Motion Intelligence
- Control Modes: Position, Speed, and Torque.
- Feedback Resolution: Supports 20-bit incremental encoders (1,280,000 pulses/rev) and 17-bit absolute encoders.
- Electronic Cam (E-CAM): Built-in logic with up to 720 points for master-slave synchronization.
- Specialized "U" Features: Includes digital command support, high-speed position capture/compare, and an extension port for digital inputs.
Suppression & Safety
- Vibration Suppression: Dual low-frequency vibration filters to prevent mechanical shaking during movement.
- Resonance Suppression: Features high-frequency auto-notch filters to eliminate mechanical "humming."
- Safety Function: Built-in Safe Torque Off (STO), ensuring hardware-level power cut-off for operator safety.
Connectivity & I/O

Function
The ASD-A2-1021-U acts as the high-speed controller for the 1.0 kW motor, specializing in:
- Torque Management: It provides the high current necessary to reach the motor's 4.77 Nm rated torque, ensuring stable performance even under heavy loads.
- Advanced Networking: The "U" suffix denotes high-speed digital communication capabilities (RS-485/Modbus) and an extension port for additional I/O.
- Electronic Cam (E-CAM): Features built-in E-CAM functions for complex master-slave synchronization without an external controller.
- Resonance Suppression: Includes advanced Vibration Suppression algorithms specifically useful for medium-inertia setups to eliminate mechanical "humming" or shaking.
