Structural Characteristics: Vertical modular cabinet mounting structure, DIN rail buckles and screw mounting holes on rear side Metal frame matched with flame‑retardant plastic protective cover Front panel LED status indicators showing running, fault and bus status Main circuit power terminals on upper section, control signal terminals on lower section Side slots reserved for communication option cards Physical separation between power cavity and signal cavity to reduce electromagnetic interference
Working Principle: Three‑phase AC power connects to main circuit terminals. Rectifier bridge converts alternating current into DC bus voltage. IGBT inverter module outputs three‑phase AC with continuously adjustable voltage and frequency to drive synchronous servo motor. Encoder collects real‑time rotor speed and position signals and feeds back to the inverter. CFC closed‑loop vector algorithm continuously calculates motor flux, rotor position and output torque, dynamically adjusts output voltage and frequency to complete high‑precision closed‑loop speed regulation. Regenerative energy generated during load decimation passes through built‑in brake chopper and releases to external brake resistor. Hardware protection circuit cuts off power output immediately when fault occurs, fault indicator lights up and fault code is stored.
Installation Requirements: Vertical upright installation only inside closed electrical cabinet. Inverted or horizontal installation is forbidden Reserve upper and lower ventilation gaps inside cabinet without blocking cooling air channel Separate routing for power cables and signal cables, all signal cables adopt shielded cables Input power voltage must match nameplate rating Installation environment excludes dust, corrosive gas and condensed water vapor PE protective earth connection must be firmly fastened Encoder cable uses SEW specified shielded encoder cable
Precautions for Use: Wait at least 10 minutes after power‑off for full discharge of DC bus capacitor before opening cover for maintenance Verify input voltage against nameplate before power‑on Complete full motor identification procedure during commissioning Capacitors and surge absorbers cannot be connected in parallel at output side Clean cooling channel dust regularly to avoid overtemperature fault ESD anti‑static protection must be implemented when plugging or unplugging communication option cards External brake resistor must match specification, short‑circuit of brake terminals is prohibited STO safety circuit wiring strictly complies with safety manual specifications
