The AC650V is a programmable sensorless vector drive designed to provide improved motor control of induction motors up to 110kW. The drive comes with built in value added application macros that make for quick setup of frequently encountered applications

The AC650V expands upon the simple, no-fuss philosophy of the AC650 and provides reliable, robust motor speed control from 0.25kW to 110kW (0.3 to 150 HP). With the addition of sensorless flux vector technology, the AC650V allows improved motor speed control at lower speeds, better speed regulation of variable loads and higher starting torques for high inertia systems. The variable torque configuration option on frames C-F makes the AC650V ideally suited to energy saving in pump and fan applications.

Features and Advantages:

The AC650V offers the same high level of specification as the AC650 and also includes:

  • High torque sensorless vector control mode for advanced motor control
  • Selectable constant torque or (higher) variable torque rating for centrifugal pump and fan applications allowing optimum inverter sizing to suit the application
  • Fully configurable with graphical software tools such as DSE Lite
  • Additional user configurable I/O points offering increased control capabilities
  • Additional PROFIBUS communications options for integration into PLC systems
  • Wall and panel mounting options above 7.5kW
  • Extended power range to 110kW makes the AC650V suited to a wide variety of uses.
