Working Principle

1. AC mains input passes EMI filter to rectify stable DC bus voltage;
2. DSP chip receives upper motion command and motor feedback signal, executes real-time vector decoupling operation;
3. PWM power modulation signal drives IGBT power module to output three-phase sine wave current to servo motor stator winding;
4. Real-time sampling of bus voltage, output current, module temperature, and feedback position signal to form full closed-loop regulation;
5. Hardware safety circuit triggers STO shutdown within 2μs when fault threshold is exceeded to cut motor torque output.

Function Features

1. One-click automatic inertia identification and servo loop auto-tuning, compatible with 1000:1 load inertia ratio;
2. Built-in 300 groups of independent motion segment storage without external PLC auxiliary positioning;
3. Real-time six-channel software oscilloscope for dynamic performance capture and machine vibration diagnosis;
4. Integrated electronic cam and flying shear function for continuous web processing equipment;
5. Dual-channel SIL3/PLe STO safety function compliant with IEC 61800-5-2 functional safety standard;
6. Support DC bus parallel sharing for multi-axis system energy circulation regeneration.

5. Low electromagnetic interference via built-in high-performance EMC filter, eliminates external filter extra cost.

Applicable Industries

Installation Requirements

1. Mount vertically inside IP20 protection electrical cabinet only, minimum clearance 50mm top, 30mm bottom, 10mm left/right between adjacent drives;
2. Ambient operating temperature range: 0°C ~ +55°C, storage temperature: -20°C ~ +70°C;
3. Relative humidity ≤85% non-condensing, install dehumidifier if ambient humidity exceeds 70%;
4. Separate power cable and signal cable wiring, maintain minimum 10cm distance, shield cable single-end grounding at drive side only;
5. Connect external braking resistor when load regenerative energy exceeds internal absorption capacity;
6. Secure DIN rail buckle lock to prevent vibration loosening during equipment high-speed reciprocation.

Usage Precautions

1. Power on sequence: First supply 24VDC auxiliary control power, then switch main AC power; power-off sequence reversed to avoid circuit board surge damage;
2. Do not disconnect feedback cable while drive is powered on, will trigger irreversible overvoltage fault;
3. Avoid operation in environment with conductive dust, corrosive gas, oil mist;
4. Conduct regular heat grille dust cleaning every 3 months to prevent overheat derating;
5. DC bus parallel connection requires matched drive power grade, install current balancing reactor for power difference >30%;
6. Fault alarm must be fully cleared and root cause eliminated before restart operation, prohibited forced power reset continuous trial run.
