Working Principle

1. Low-voltage AC mains filtered and rectified to stable DC bus voltage for power inverter stage;
2. Dual-core processor separates real-time current loop calculation and upper motion logic processing to eliminate computation delay;
3. PWM modulation signal drives IGBT inverter to output three-phase sine wave excitation current to servo motor stator;
4. Real-time feedback signal sampling executes closed-loop correction of speed, torque and position within microsecond cycle;
5. Hardware STO circuit immediately disables PWM output upon safety interlock trigger to cut motor torque;
6. RJ45 EtherCAT port receives deterministic motion commands from host PLC with sub-millisecond synchronization cycle.

Function Features

1. Kollmorgen WorkBench software one-click auto-tuning, automatic load inertia and friction parameter identification;
2. Embedded 256-segment motion profile storage for standalone point-to-point positioning without host controller;
3. Native SFD single-cable motor connection, power and feedback integrated into one cable to reduce wiring quantity by 50%;
4. Six-channel real-time software oscilloscope for capturing transient motion response and machine vibration waveform;
5. Built-in multi-order notch filter to suppress mechanical resonance across full speed range;
6. Hot-pluggable EtherCAT communication bus without drive power cycle for system expansion.

4. Global CE, UL, RoHS certified for medical, food, semiconductor cleanroom equipment application;
5. Complete single-cable motor ecosystem cuts wiring labor and cable inventory cost for OEM manufacturers.

Applicable Industries

Installation Requirements

1. Vertical DIN rail mounting only inside IP20 electrical cabinet; minimum clearance 40mm top, 20mm bottom, 5mm between adjacent drives;
2. Ambient operating temperature range: 0°C ~ +55°C, derate output power 15% continuously above 45°C ambient;
3. Non-condensing relative humidity ≤85%, prohibited installation near water cooling pipelines without waterproof baffle;
4. Shielded motor and feedback cables must use 360° metal gland grounding at cabinet entry point;
5. External braking resistor required when cyclic deceleration regenerative energy exceeds internal absorption capacity;
6. Cabinet EMC shielding partition recommended for installation near high-frequency inverter equipment.

Usage Precautions

1. Auxiliary 24VDC control power must remain powered during equipment standby to retain fault history and parameter storage;
2. Do not hot-unplug SFD single cable during drive operation, will trigger emergency STO shutdown;
3. Avoid installation in environments with conductive dust, alcohol vapor, or fine powder pollution;
4. Cabinet ventilation grille dust cleaning every 6 months for low-dust workshop, every 2 months for dusty production lines;
5. Do not connect multiple drives to one shared 24VDC auxiliary power supply without overcurrent fuse protection per drive;
6. After fault alarm elimination, execute full parameter backup before resuming production operation.
