Working Principle: Three-phase AC power accesses power unit terminals. Rectifier circuit converts AC to DC bus voltage. IGBT power module outputs adjustable three-phase AC to drive synchronous servo motor. Encoder feeds rotor speed and absolute position signal back to control unit. CFC closed-loop vector algorithm calculates motor flux and output torque dynamically to adjust output voltage and frequency for high precision speed and position control. Regenerative energy during deceleration is consumed on external brake resistor through built-in brake chopper. Fault signal triggers hardware protection and cuts power output immediately.
Installation Requirements: Vertical upright installation inside closed electrical cabinet, inverted or horizontal installation forbidden Reserve large ventilation space and ensure cooling fan air inlet and outlet unobstructed Power cables and signal cables are routed separately, all signal cables adopt shielded cables Three-phase input voltage must match nameplate rating Installation environment excludes dust, corrosive gas and condensed water PE protective earth terminal must be firmly connected to ground busbar Encoder cable must use SEW designated shielded cable
Precautions for Use: Wait at least 15 minutes after power-off for DC bus capacitor full discharge before opening cover for maintenance Check three-phase input voltage consistency before power-on Complete full motor identification during commissioning Capacitors and surge absorbers cannot be connected in parallel at output side Clean cooling fan and heat sink dust periodically ESD anti-static protection must be adopted when replacing communication cards External brake resistor must match power specification, brake terminal short-circuit prohibited STO safety circuit wiring strictly follows official safety manual
