Product Overview
The AC650G is an entry level AC drive designed to provide cost-effective control of AC induction motors used in many everyday industrial applications, up to 7.5kW, and is ideally suited to energy saving in pump and fan applications.
Detailed Information
The economical AC650G is ideally suited to applications requiring accurate control at lower speeds, higher starting torques, or where improved speed regulation of variable loads is important. Whether you need to control a conveyor belt, automatic barrier, machine spindle or other high performance application, the sensorless vector technology of the AC650G delivers improved control.
Designed with simplicity in mind, the AC650G comes in a compact format with DIN rail mounting as standard allowing easy integration into any electrical control panel. The operator/programming keypad can be removed after setup to prevent unauthorized changes to inverter configuration. For simple high performance motor speed control up to 7.5kW, the AC650G is an easy to use, out of the box solution that will have your system up and running in no time.
Features:
• High torque sensorless vector control for advanced motor control
• Integrated operator keypad with option for remote mounting
• Profibus, RS232, RS485 communication option for PLC integration
• Flexible I/O including analog and relay output and motor thermistor input allowing greater control options
• Pre-programmed Macros allowing quick and simple drive setup
• DIN rail mounting for easy integration into any electrical cabinet
• 6514 cloning module option allows easy back-up and transfer of parameters between different drives
Advantages:
• Diagnostic and control through the operator keypad
• Simplified operation throught the use of pre-programmed macros:
– Simple Speed Control : set speed and voltage or current with start / stop direction control.
– Manual/Automatic Control : set to run with local speed setting or external reference.
– Preset Speed Control : select up to 8 pre-programmed speeds using digital inputs.
– Increase/Decrease : increase or reduce speed using digital inputs.
– PID Control : control the pressure, flow, temperature or any process variable.
