The AC650 is a simple, compact and cost effective solution for basic Volts/Hertz open-loop motor speed control applications up to 7.5kW, such as conveyors, automatic barriers and machine spindles

Whether you need to control a conveyor belt, automatic barrier, machine spindle or other general purpose application, the AC650 series of variable frequency AC drives deliver reliable, cost-effective voltage/frequency speed control of your motor. Designed with simplicity in mind, the AC650 drives come 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 unauthorised changes to inverter configuration. For simple motor speed control up to 7.5 kW (10HP), the AC650 series variable frequency AC drives provide an easy to use, out of the box solution that will have your system up and running in no time.


  • Integrated operator keypad with option for remote mounting
  • Integrated EMC filter ensures compliance while maintaining a compact footprint
  • Flexible I/O including analogue and relay output and motor thermister 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


  • 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 input.
    - Increase / Decrease : increase or reduce speed using digital inputs
    - PID Control : control the pressure, flow, temperature or any process variable.
