S72402-NANANA-NA-225 Servo Drive

Three-Closed-Loop Control Architecture: Based on full closed-loop control of position loop, speed loop, and current loop, combined with adaptive PID adjustment, it supports nanometer-level positioning accuracy (e.g., ±1μm), suitable for precision scenarios such as semiconductor wafer handling and electronic component mounting.

High Dynamic Response Characteristics: Supports 0-3000rpm acceleration time ≤30ms. With S-curve/trapezoidal curve trajectory planning, it enables high-speed start-stop and complex path tracking, reducing motion impact and vibration.

Flexible Switching of Multiple Control Modes: Supports position control (pulse/direction input), speed control (analog/communication command), and torque control (current closed-loop), and allows seamless mode switching through parameter configuration.

Compact and Efficient Architecture: Rated power 2.4kW, peak power up to 7.2kW, body size only 120×120×160mm, suitable for miniaturized equipment (e.g., collaborative robots, compact production lines); adopts low-loss IGBT modules and heat sink design, with efficiency ≥97% and 20% reduced temperature rise.

Wide Working Condition Adaptability: Operating temperature -10℃~+50℃ (with derating), protection class IP20 (optional IP65 protection kit), supporting stable operation in harsh environments (dust, oil pollution).

Comprehensive Industrial Communication Protocols: Standard EtherCAT interface (communication cycle ≤1ms), optional Profinet, Modbus TCP, CANopen, etc., compatible with PLC, robot controllers (e.g., ABB, Fanuc), and host systems.

High-Precision Feedback Support: Built-in 24-bit absolute encoder (EnDat 2.2 protocol), position resolution up to 16 million pulses/revolution, supporting real-time position, speed, and temperature feedback to ensure closed-loop control stability.

Multiple Hardware Protections: Integrates overcurrent, overvoltage, overheating, short-circuit, and undervoltage protections, supports emergency stop (STO) function, and complies with ISO 13849 safety standards.

Fault Self-Diagnosis and Recording: Monitors operating status in real time through LCD panel or host software, stores the latest 50 fault logs, and supports remote debugging and maintenance (e.g., parameter backup, online upgrade).

Current Loop: Drives IGBT power modules through PWM modulation to output precise three-phase current to the servo motor, generating electromagnetic torque; samples current feedback in real time, compares it with the command value, and adjusts the output to suppress current fluctuations.

Speed Loop: Based on the motor speed fed back by the encoder, adjusts the current loop command through PID algorithm to ensure stable motor speed (e.g., fluctuation ≤±0.1% at target 3000rpm).

Position Loop: Compares the position value fed back by the encoder with the target position, calculates the deviation, and generates a speed command to achieve sub-micron positioning (e.g., positioning error ≤±1μm).
