Working Principle: Three-phase AC power enters main circuit terminals. Internal rectifier bridge converts alternating current into stable DC bus voltage. IGBT inverter module outputs continuously adjustable three-phase AC to drive asynchronous motor. Encoder feeds rotor speed and position signals back to control board. CFC closed-loop vector algorithm continuously calculates motor flux and output torque, dynamically adjusts output voltage and frequency to realize high-precision speed and position closed-loop regulation. Regenerative energy generated during deceleration is dissipated by built-in brake chopper into external brake resistor. When fault occurs, hardware protection circuit immediately cuts power output, lights fault indicator and stores fault information. Multiple drives share regenerative energy through DC bus interconnection terminals.
Installation Requirements: Vertical upright installation only inside closed electrical cabinet, inverted or horizontal installation forbidden Reserve sufficient upper and lower cooling clearance, keep cooling fan inlet and outlet unobstructed Separate routing for power cables and signal cables, all signal cables use shielded cable Three-phase input voltage must match nameplate rating Cabinet environment free of dust, corrosive gas and condensed water vapor PE protective earth terminal firmly connected to cabinet ground busbar Encoder cable uses SEW dedicated shielded cable Metal shielding cover must be fitted after option card installation
Precautions for Use: Wait at least 10 minutes after power-off for full DC bus capacitor discharge before opening the cover for maintenance Verify three-phase input voltage balance before power-on Complete full motor identification during commissioning No parallel capacitors or surge absorbers on the inverter output side Clean cooling fan and heat sink dust regularly to avoid overtemperature shutdown Implement ESD protection when plugging option cards and control components External brake resistor must match drive rating, brake terminal short-circuit prohibited STO safety circuit wiring strictly follows the official safety manual
