Technical Specifications: Single‑phase 115‑230 VAC input; continuous output current 10 Arms; peak output current 20 Arms; switching frequency 22 kHz; ±10 V analog command interface; support resolver and incremental encoder feedback; isolated digital enable, fault relay output; operating temperature range 0 ℃‑50 ℃; storage temperature ‑20 ℃‑85 ℃; relative humidity 5%‑95% non‑condensing; protection functions include over‑current, over‑temperature, DC bus over‑voltage and under‑voltage; panel‑mount chassis structure; weight 2.7 kg.
Functional Features: Four‑quadrant regenerative power operation; hardware current‑limiting protection; adjustable PI loop gain via potentiometers; resolver‑based commutation for brushless motors; fault relay contact output for system alarm; support external regeneration resistor connection; analog monitor test points for real‑time signal observation; hardware inhibit input for emergency stop.
Application Scenarios: Legacy CNC machine tools, industrial robotic equipment, packaging automation machinery, material handling equipment, retrofitting and spare‑part replacement for vintage automated production lines.
Performance Parameters: Current‑loop bandwidth up to 1200 Hz; velocity‑loop bandwidth adjustable up to 450 Hz; short‑term 200% peak overload capacity for 30 seconds; fast hardware fault detection and latch‑up; regenerative energy handling for motor deceleration condition.
Material Composition: Die‑cast aluminum alloy housing; high‑power IGBT power modules; gold‑plated industrial connectors; flame‑retardant high‑voltage PCB circuit board; metal heat sink fins; status LED indicator array; metal locking mounting brackets.
Structural Features: Compact panel‑mount metal chassis; front panel fitted with adjustment potentiometers and status LED indicators; rear section equipped with power terminals, motor connector, feedback connector and analog signal terminals; non‑fan convection cooling structure; all external signal ports adopt industrial‑grade locking connectors.
Working Principle: AC input power is rectified into DC bus voltage. Power semiconductor devices output three‑phase variable‑frequency current to drive brushless servo motor. Resolver or encoder feedback delivers rotor position and velocity signals into analog PI control circuits. The amplifier responds to ±10V external analog command to realize torque and velocity closed‑loop regulation. Hardware monitoring circuits continuously sample current, temperature and bus voltage. Fault conditions trigger immediate power stage shutdown and activate fault relay output.
Installation Requirements: Install vertically inside industrial control cabinet; maintain 70 mm upper‑lower ventilation clearance and 40 mm left‑right clearance; separate power cables and signal cables with physical distance greater than 12 cm; all shielded signal cables implement single‑end shield grounding; connect unit protective earth terminal to cabinet grounding bar reliably; install external regeneration resistor according to actual deceleration energy demand.
Usage Notes: Allow sufficient DC‑bus bleeding‑off time before opening cabinet for maintenance; strictly prohibit live‑plugging motor and feedback connectors; do not exceed rated input voltage and output current parameters; regularly inspect fault relay and terminal tightening status; replacement spare parts must match hardware revision and motor feedback type.
