Material Composition
Chassis: galvanized steel sheet with powder coating. Power section: IGBT power modules. Heat sink: extruded aluminum. Control board: FR-4 PCB with conformal coating. Terminals: tin-plated copper alloy.
Structural Characteristics
It features book-style chassis, front panel operator keypad with LED display, terminal block input/output connections, integrated EMC filter, bottom cooling fins and DIN rail mounting points.
Working Principle
It rectifies 3-phase AC input to DC link voltage, then inverts the DC to variable-voltage variable-frequency 3-phase AC output via IGBT power stage. Sensorless vector control algorithm models motor flux and torque to provide precise speed and torque control without encoder feedback.
Installation Requirements
Mount on wall or DIN rail with specified clearances for ventilation. Use appropriately sized copper cable for input and motor connections. Connect protective earth conductor reliably. Install external brake resistor if required. Ensure adequate air flow through cooling fins.
