Working Principle

1. Power Rectification & Inversion Stage: Input AC power is rectified into DC bus voltage through internal rectifier circuit; DSP digital chip outputs PWM pulse width modulation signal to control IGBT power tube inversion, output three-phase adjustable frequency and adjustable voltage AC power to drive servo motor
2. Feedback Signal Sampling Stage: Real-time collect motor rotor position and speed signals through encoder/resolver feedback channel, transmit feedback data to main control DSP chip
3. Three-Loop Closed-Loop Calculation Stage: DSP chip receives position/speed/torque command signals from upper controller through analog, pulse or fieldbus; compare command value and actual feedback value to calculate error, adjust PWM output signal through PID algorithm to eliminate motion error
4. Built-in PLC Logic Operation Stage: Independent PLC processing unit collects digital input signals of equipment limit switch, photoelectric sensor; execute pre-programmed interlock logic, output control signals to relay, solenoid valve and other execution components through digital output channels
5. STO Safety Protection Working Logic: When external safety door, emergency stop safety signal is triggered, STO hardware circuit directly cuts off the drive output PWM signal, the motor loses driving torque immediately; the drive keeps fault lock state until manual safety reset

Installation Requirements

1. Installation Direction: Must be installed vertically; heat dissipation fins must keep vertical upward air circulation, horizontal or inverted installation is prohibited
2. Cabinet Installation Spacing: Reserve more than 50mm heat dissipation gap above and below the drive; when multiple servo drives are installed side by side, the horizontal gap between two drives must be greater than 30mm
3. Wiring Specification:
   • Power cable: Use shielded three-core copper cable with wire diameter matching output current; shielding layer single-point grounding at cabinet ground bar
   • Encoder feedback cable: Special double-shielded high-flex servo encoder cable, separate wiring trough from power cable to avoid electromagnetic interference
   • STO safety signal cable: Independent twisted pair shielded cable, cannot be bundled with power cable

5. General industrial automation equipment: Small CNC drilling and milling machines, cutting equipment, automatic conveying positioning trolleys

Operation & Maintenance Precautions

1. Before power-on, check whether the STO safety circuit wiring is intact; emergency stop and safety door signals must be connected to STO dedicated terminals, cannot use ordinary digital input terminals instead
2. Do not plug or unplug encoder feedback cables when the drive is powered on; hot plug will cause permanent damage to the feedback signal chip
3. Regularly clean the radiator heat dissipation fins every three months, remove accumulated dust and lint to avoid poor heat dissipation triggering over-temperature fault alarm
4. When modifying electronic cam, electronic gearing motion parameters, stop the equipment axis operation first, parameter modification during high-speed operation will cause axis runaway risk
5. The built-in PLC program modification must save the program file to the upper computer for backup; after program loss due to power failure, the backup file needs to be re-downloaded
6. If over-current, over-voltage fault codes appear frequently, check whether the servo motor winding insulation is damaged, whether the power cable has short-circuit hidden dangers
7. Storage environment of spare drives must keep dry, avoid long-term storage in high-humidity and low-temperature environment to prevent circuit board moisture corrosion
