Structural Characteristics: Vertical heavy-duty cabinet mounting structure with multiple heavy-load screw fixing holes Pluggable control card on front side for easy replacement and maintenance Separated power cavity and control cavity for electromagnetic interference suppression Front multi-group LED indicators to display running, fault, bus and diagnosis status Top section high-current main circuit terminals, lower section control signal terminals Side slots reserved for communication option card installation Dual high-power cooling fans dedicated for power unit heat dissipation
Working Principle: Three-phase AC power enters the power unit and is rectified into DC bus voltage by internal rectifier bridge. High-power IGBT power module converts DC voltage into adjustable three-phase AC to drive large synchronous servo motor. Encoder feeds rotor speed and position signal back to pluggable control card. CFC closed-loop vector algorithm calculates motor flux and torque in real time and dynamically adjusts output voltage and frequency to realize high-precision speed, torque and electronic cam control. Regenerative energy generated during deceleration passes built-in brake chopper and dissipates in external brake resistor. Fault information will be automatically stored in control card for later diagnosis.
Installation Requirements: Vertical upright installation inside closed electrical cabinet, inverted or horizontal installation forbidden Reserve large cooling space, cooling fan air inlet and outlet cannot be blocked Power cables and signal cables are routed separately, signal cables must adopt shielded cables Three-phase input voltage must match nameplate rating Installation environment excludes dust, corrosive gas and condensed water vapor PE protective earth terminal must be firmly connected to heavy-duty ground busbar Encoder cable must use SEW designated shielded cable
