Working Principle: Three-phase AC power enters the main circuit. The rectifier bridge converts it into a stable DC bus voltage. The IGBT inverter outputs adjustable three-phase AC to drive the motor. The encoder feeds rotor speed and position back to the control board. The CFC closed-loop vector algorithm dynamically adjusts output voltage and frequency for high-precision closed-loop regulation. Regenerative energy during deceleration is dissipated by the brake chopper into the external brake resistor. On fault, the hardware protection cuts power output, lights the fault indicator and stores fault information. Multiple drives can share regenerative energy through DC bus interconnection.
Installation Requirements: Vertical upright installation only inside a closed electrical cabinet, inverted or horizontal installation forbidden Reserve sufficient cooling clearance, keep fan inlet and outlet unobstructed Separate power and signal cable routing, all signal cables shielded Input voltage matches nameplate rating Cabinet environment free of dust, corrosive gas and condensation PE earth terminal firmly connected to ground busbar Encoder cable uses SEW dedicated shielded cable Fit metal shielding cover after option card installation
