Technical Specifications
Rated power: 1.5kW. Input voltage: 380-480V AC 3-phase. Output current: 3.7A. Output frequency: 0Hz to 650Hz. Control modes: V/Hz, sensorless vector. Overload capacity: 150% for 60s, 200% for 2s. Operating temperature range: -10°C to +50°C. Protection rating: IP20.
Functional Features
Sensorless vector control delivers high low-speed torque. Integrated brake chopper. Programmable acceleration/deceleration ramps. Multiple preset speeds. Built-in motor protection. Keypad with parameter display.
Application Scenarios
It controls conveyor systems, machine tool drives, material handling equipment, pumps, fans and general industrial variable-speed applications.
Performance Parameters
Speed range: 1:100 vector mode. Starting torque: 150% at 0Hz. Speed regulation: ±0.5% vector mode. Efficiency: 95% @ rated load. Operating temperature range: -10°C to +50°C.
Material Composition
Chassis: powder-coated steel. Power stage: IGBT power module. Heat sink: extruded aluminum. Control PCB: FR-4 with conformal coating.
Structural Characteristics
It features compact book-style housing, front operator keypad with LED display, terminal blocks, cooling fan, and DIN rail mounting points.
Working Principle
It rectifies AC input to DC link voltage, then inverts to variable-voltage variable-frequency AC via IGBTs. Vector control algorithm models motor flux and torque for independent control of both quantities.
Installation Requirements
Mount on DIN rail or panel. Use appropriately sized cables. Connect PE ground. Install brake resistor for dynamic braking.
Usage Notes
Wait for DC link discharge before servicing. Run auto-tuning for optimal performance. Keep heat sink clean. Do not operate with phase loss.
