E: Represents hardware/firmware configuration (E = Enhanced Feedback Compatibility + Industrial Ethernet Support + Basic Safety Functions), supporting advanced encoder protocols, native industrial communication, and global industrial standards. Key Performance Specifications Electrical Ratings Input Voltage: 200–240V AC (single-phase, ±10% tolerance), suitable for global low-voltage industrial power grids and miniaturized automation systems. Maximum Output Current: 2.1A rms (continuous); 6.3A rms (peak, 1-second duration) – ideal for driving ultra-small servo motors (0.1–0.4kW) in precision micro-motion systems. Power Consumption: ≤180VA (no-load); ≤750VA (full-load, dependent on motor efficiency) – 10% higher energy efficiency compared to Delta’s previous-generation low-power servo drives. 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/PID + Velocity/Acceleration Feedforward), Speed Control (PI + Feedforward), Torque Control (P/PI), Profile Position Mode (Trapezoidal/S-Curve/Jerk-Limited Acceleration), Electronic Gearbox, and Master-Slave Synchronization. Positioning Resolution: Up to 1,048,576 pulses/rev (20-bit absolute encoder compatible) / 100,000 pulses/rev (incremental encoder), enabling sub-micron precision (≤0.05μm for linear applications with 0.5mm-lead ball screws) for high-accuracy micro-processing tasks. Dynamic Response: Speed loop bandwidth ≥400Hz; Position loop bandwidth ≥180Hz – ensuring rapid settling time (≤4ms) and minimal overshoot (<3%) for high-cycle micro-motion sequences (e.g., micro-assembly, precision feeding of tiny components). Vibration Suppression: Adaptive single-band notch filter, resonance suppression algorithm, and friction compensation – effectively reducing mechanical vibration in ultra-lightweight systems (e.g., micro-robotic arms, mini linear stages) and eliminating resonance-induced positioning errors. Low-Speed Stability: Enhanced current ripple suppression and adaptive cogging compensation algorithm to ensure smooth operation at ultra-low speeds (≥0.05rpm), critical for precision micro-adjustment tasks (e.g., micro-engraving, fine positioning of small parts). Feedback & Communication Feedback Interface: Supports absolute encoders (BiSS C, EnDat 2.2, Delta’s proprietary encoder), incremental encoders (A/B/Z phases, differential output, up to 500kHz), and resolvers (via optional adapter) – compatible with Delta ASD-B3 series ultra-small servo motors and third-party low-power servo motors. Communication Protocols: Native support for EtherCAT (CoE – CANopen over EtherCAT), Modbus RTU (RS-485), and CANopen; Pulse/Direction input for standalone operation – seamless integration with high-performance PLCs, microcontrollers, and motion control cards.
