Description
ABB AC160
Technical Specifications:
- Input Voltage: Three-phase 380-480V AC.
- Power Range: Covers fractional to low horsepower motor ratings.
- Control Modes: Scalar (V/f) and Sensorless Vector control.
- Protection Class: IP20 (standard).
Functional Features:
- Energy Optimization: Automatic energy optimization reduces power consumption during partial loads.
- Built-in EMC Filter: Integrated electromagnetic compatibility filter reduces electrical noise.
- Intuitive HMI: Keypad with clear display for easy parameter setup and monitoring.
- Safe Torque Off (STO): Integrated safety function to safely disable motor torque.
Application Scenarios:
- Conveyor belts, fans, and pumps.
- Packaging and material handling machinery.
- Machine tools and textile equipment.
Performance Parameters:
- Overload Capacity: Typically 110% for 60 seconds (heavy duty) or 150% for 60 seconds (normal duty).
- Speed Control Range: Wide speed regulation with high torque at low speeds.
Material Composition & Structural Characteristics:
- Heat Sink: Aluminum extrusion heat sink for efficient thermal management.
- Enclosure: Compact plastic housing with integrated cooling fan.
Working Principle:
Converts incoming AC power to DC via a rectifier, smooths it with a DC bus capacitor, and then uses an IGBT inverter to synthesize a variable-frequency, variable-voltage AC output. This allows precise control of motor speed and torque.
Installation Requirements:
- Cooling: Maintain minimum clearance above and below the drive for proper airflow.
- Wiring: Use shielded motor cables and separate control wiring from power cables.
Usage Precautions:
- Motor Data: Accurately enter motor nameplate data during commissioning for optimal control.
- Grounding: Ensure solid grounding of the drive and motor to prevent bearing currents and EMI.
