Core Features The ASD-A0221LA is a high-performance compact low-power servo drive from Delta Electronics (a global leader in industrial automation, power electronics, and motion control solutions), belonging to Delta’s ASD-A series—engineered for small-scale industrial applications requiring exceptional space efficiency, precise motion control, and seamless integration with small servo motors. This servo drive excels in scenarios where miniaturization, low power consumption, and reliable torque/speed/position regulation are critical (e.g., small CNC machines, robotic end effectors, automated micro-assembly lines, and precision linear stages). Following Delta’s standardized ASD-A series naming convention, the alphanumeric suffixes encode key technical configurations for intuitive identification: ASD: Denotes Delta’s core servo drive platform (ASD = Advanced Servo Drive), designed for industrial-grade durability, low noise, and broad application versatility. A: Signifies the low-power compact class (A = Compact + Low-Power + Cost-Effective), optimized for small-load motion systems balancing precision and affordability. 0221: Specifies the maximum output current rating = 2.2A rms (continuous), tailored for small servo motors (0.1–0.4kW) in low-to-medium duty cycle applications. LA: Represents hardware/firmware configuration (L = Low-Profile Design + A = Enhanced Feedback Compatibility + Basic Safety Functions), ensuring compatibility with global low-voltage power grids and mainstream small servo motors, with a focus on space-saving installation. Key Performance Specifications Electrical Ratings Input Voltage: 200–240V AC (single-phase, ±10% tolerance), suitable for global low-voltage industrial power grids and compact automation systems. Maximum Output Current: 2.2A rms (continuous); 6.6A rms (peak, 1-second duration) – ideal for driving small servo motors (0.1–0.4kW) in precision motion systems. Power Consumption: ≤220VA (no-load); ≤850VA (full-load, dependent on motor efficiency). Control Power Supply: 24V DC ±10% (0.8A typical), powered via external industrial power supply or optional internal auxiliary power module. Control Performance Control Modes: Position Control (P/PI + Velocity Feedforward), Speed Control (PI + Feedforward), Torque Control (P/PI), Profile Position Mode (Trapezoidal/S-Curve Acceleration/Deceleration), and Electronic Gear Ratio Adjustment. Positioning Resolution: Up to 524,288 pulses/rev (19-bit absolute encoder compatible) / 100,000 pulses/rev (incremental encoder), enabling micron-level precision (≤0.1μm for linear applications with 1mm-lead ball screws) for high-accuracy small-part processing. Dynamic Response: Speed loop bandwidth ≥320Hz; Position loop bandwidth ≥130Hz – ensuring rapid settling time (≤5ms) and minimal overshoot (<5%) for high-cycle small-motion sequences (e.g., micro-assembly, precision feeding). Vibration Suppression: Built-in single-band notch filter and low-resonance control algorithm – effectively reducing mechanical vibration in lightweight systems (e.g., small robotic arms, mini linear stages) and eliminating resonance-induced positioning errors. Low-Speed Stability: Enhanced current ripple suppression and cogging compensation algorithm to ensure smooth operation at low speeds (≥0.1rpm), critical for precision micro-adjustment tasks (e.g., small-part engraving, fine positioning). Feedback & Communication Feedback Interface: Supports incremental encoders (A/B/Z phases, differential output, up to 300kHz) and absolute encoders (BiSS C, Delta’s proprietary encoder), enabling flexible compatibility with Delta ASD-A series small servo motors and third-party low-power servo motors. Communication Protocols: Modbus RTU (RS-485), CANopen, and Pulse/Direction input (for standalone operation) – seamless integration with small PLCs, motion controllers, and industrial PCs. I/O Signals: 8 digital inputs (photo-coupler isolated, 24V DC), 4 digital outputs (transistor open-collector, 24V DC), 1 analog input (±10V, 12-bit resolution for torque/speed command), 1 analog output (±10V, 12-bit resolution for status monitoring). Safety & Protection Safety Function: Safety Torque Off (STO, EN ISO 13849-1 Category 2, PL c) – prevents motor torque output when a safety signal is triggered, ensuring operator and equipment safety in small-scale automation. Protection Functions: Overcurrent protection (phase-to-phase), Overvoltage protection (DC bus), Undervoltage protection, Overheating protection (heatsink), Short-circuit protection (motor/encoder), Encoder Fault detection, and Motor Overload protection.

Mounting Type: DIN rail mounting (EN 50022 standard, 35mm rail) – suitable for space-constrained installations and multi-axis stacking (e.g., small CNC machines, desktop automation equipment). Protection Rating: IP20 (front panel); IP40 (when installed in a control cabinet) – protected against dust and accidental finger contact. Operating Temperature: 0°C to +55°C (ambient); derating above 45°C (1% current reduction per °C up to 55°C) to maintain stable performance under continuous operation. Storage Temperature: -20°C to +85°C. Relative Humidity: 20% to 90% (non-condensing), compatible with industrial environments with varying humidity levels. Noise Level: ≤61dB(A) at 1m (full-load operation), low-noise design compliant with small automation, laboratory, and office-adjacent environments.
