Technical Specifications: Control mode sensor‑less current vector control, V/F open‑loop control; output‑frequency range 0.0‑400.0 Hz; pulse frequency 3‑16 kHz; overload capacity 150% for 60 seconds, 200% for 3.5 seconds; 5 digital inputs, 2 analog inputs, 2 relay outputs; interfaces RS‑232, RS‑485 USS, PROFIBUS‑DP, CANopen; protection class IP20; ambient operating temperature 0 °C ~ +50 °C; storage temperature ‑20 °C ~ +70 °C; support side‑by‑side adjacent installation without gap; automatic motor‑parameter identification function.

Functional Features: Sensor‑less vector control for high starting‑torque output; automatic motor‑parameter self‑identification; four groups of switchable parameter sets; built‑in PID process controller; DC braking function; complete multiple protection functions; multiple industrial‑bus communication options; parameter storage and backup function; motor‑temperature PTC monitoring function; digital‑potentiometer simulation function.

Application Scenarios: Conveyor‑belt drive control, fan‑pump energy‑saving speed‑regulation, packaging‑machine drive, material‑handling equipment, general‑purpose mechanical asynchronous‑motor speed‑regulation in factory automation production‑lines.

Performance Parameters: Analog‑command value constancy analog <1%, digital <0.02%; relay output contact rating 2 A 230 V AC; efficiency up to 96%; over‑voltage, under‑voltage, short‑circuit, ground‑fault, over‑temperature, overload protection.

Material Composition: Metal alloy housing; FR‑4 power‑circuit board and control‑circuit board; IGBT power‑switching devices; electrolytic power capacitors; optocoupler isolation chips; terminal‑block for power and signal wiring; cooling radiator.

Structural Characteristics: Compact vertical cabinet‑mount structure; top‑side power‑wiring terminals, lower‑side signal‑wiring terminals; built‑in radiator for heat dissipation; side‑by‑side installation without spacing requirement; front‑panel operation‑keypad and status‑LED indicator; optional external communication‑bus adapter module.

Working Principle: After three‑phase AC power input, rectifier circuit converts AC into DC bus voltage; IGBT inverter circuit converts DC into adjustable‑frequency adjustable‑voltage three‑phase AC output to drive asynchronous motor; sensor‑less vector‑control algorithm calculates motor‑rotor position and current through motor mathematical model, realizing high‑performance speed‑torque control; internal sampling circuit monitors voltage, current and temperature signals, and executes protection action when abnormal value appears.

Installation Requirements: Install inside IP20 control cabinet; vertical mounting orientation; ensure sufficient upper‑and‑lower ventilation clearance; power‑cable and signal‑cable must be routed separately; motor‑cable use shielded cable; protective ground connection is mandatory; derating operation required when installation altitude exceeds 1000 m above sea‑level.

Usage Notes: Wait for capacitor discharge for specified time after power‑off before opening housing; strictly match motor‑parameter setting with actual motor; do not run beyond overload capacity; set RS‑485 bus terminal resistor for long‑distance bus communication; regular inspection of radiator dust accumulation; comply with safety‑operation specification for high‑voltage power‑unit.
