About ASD-A2-1521-U* Delta A2 Series Driver - 1500W
The ASD-A2-1521-U is the high-performance 1500W (1.5 kW) AC servo drive from Deltas premium ASDA-A2 series, designed for high-resolution control of medium-inertia motors.
Core Power & Electrical
- Rated Power: 1500 Watts (1.5 kW).
- Input Voltage/Phase: Single-phase or 3-phase, 200V ~ 230V AC (+10% / -15%), 50/60 Hz.
- Continuous Output Current: 8.3 Arms.
- Frequency Response: 1 kHz (for rapid system calculation and response).
- Speed Control Range: 1:5000.
Control & Motion Intelligence
- Control Modes: Position, Speed, and Torque (switchable via I/O or communication).
- 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 additional digital inputs.
Suppression & Safety
- Vibration Suppression: Dual low-frequency vibration filters to eliminate mechanical shaking during high-torque moves.
- 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 (SIL2/PL d).

Function
The ASD-A2-1521-U is the high-speed controller for 1.5 kW motors, specializing in:
- High-Inertia Control: Specifically tuned to provide the current required for medium-inertia motors (like the ECMA-E11315RS) to reach their 7.16 Nm rated torque.
- Smart Motion (E-CAM): Built-in Electronic Cam functionality for complex, synchronized movements (e.g., flying saws or rotary cutters) without a separate motion card.
- Advanced Connectivity: The "U" type supports high-speed digital communication (RS-485/Modbus) and features an extension port for additional digital inputs.
- Precision & Stability: Features a 1 kHz frequency response and Vibration Suppression algorithms to ensure heavy-duty movements remain smooth and accurate.
