Delta Servo Drive ASD-B0221-A

Core Features The ASD-B0221-A is a high-performance low-power servo drive from Delta Electronics (a global leader in industrial automation, power electronics, and motion control solutions), belonging to Delta’s ASD-B series—engineered for light-to-medium duty industrial applications requiring reliable precision control, broad motor compatibility, and cost-effectiveness. This servo drive excels in scenarios where precise torque/speed/position regulation, seamless integration with small servo motors, and industrial-grade durability are critical (e.g., small CNC machines, robotic end effectors, automated assembly lines, and precision linear stages). Following Delta’s standardized ASD-B 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. B: Signifies the general-purpose class (B = Balanced Performance + Cost-Effective + Wide Compatibility), optimized for small-to-medium load motion systems balancing output capacity and practicality. 0221: Specifies the maximum output current rating = 2.1A rms (continuous) – the "02" prefix indicates compatibility with 200–240V AC single-phase input, while "21" directly denotes the continuous output current, tailored for small servo motors (0.1–0.4kW) in light-duty cycle applications. A: Represents the standard hardware/firmware configuration (A = Base Model + Standard Control Features + Global Industrial Compatibility), ensuring compatibility with global low-voltage power grids and mainstream automation systems. 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: 2.1A rms (continuous); 6.3A rms (peak, 1-second duration) – ideal for driving small servo motors (0.1–0.4kW) in precision motion systems. Power Consumption: ≤200VA (no-load); ≤800VA (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 ≥300Hz; Position loop bandwidth ≥120Hz – 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-B 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 industrial environments. 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. Mechanical & Environmental Details Dimensions (W×H×D): 45mm × 150mm × 100mm (compact design with integrated heat sink), optimizing space utilization in dense multi-axis control cabinets or robotic control panels. 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: ≤60dB(A) at 1m (full-load operation), low-noise design compliant with small automation, laboratory, and office-adjacent environments. Vibration Resistance: Up to 5.9m/s² (10–500Hz), suitable for installation in low-vibration industrial settings (e.g., small machining centers, robotic workcells). Weight: Approximately 0.9–1.2kg (without mounting accessories, typical value: 1.0kg); 1.0–1.3kg (with DIN rail clips and terminal covers) – lightweight design for flexible mounting in multi-axis systems. Typical Applications Ideal for light-duty industrial automation requiring reliable precision control, compact design, and cost-effectiveness: Small CNC Machines: Mini CNC milling machines, desktop engraving equipment, and hobbyist machining tools (axis control for X/Y/Z axes) – compact size and high positioning accuracy enable machining of small components (e.g., electronic connectors, medical device micro-parts, craft materials) with tight tolerances (±0.01mm). Industrial Robotics: Small articulated robots, collaborative robot (cobot) end effectors, and delta robots for small-part handling – compact design and low noise support pick-and-place, assembly, and welding tasks in high-cycle production lines (e.g., electronic component assembly, micro-sensor manufacturing). Automated Assembly Lines: Precision assembly machines, PCB soldering equipment, and small-component handling systems – profile position control and low-speed stability enable smooth, accurate motion for high-volume assembly of small parts (e.g., smartphone components, watch parts, automotive micro-components).
