FREQROL Series

FR-A800 Series: High performance and high functionality inverter

  • The enhanced Real sensorless vector control and vector control achieves improved speed response and high-speed operation.
  • The PM motor auto tuning function enables operation of other manufacturers’ permanent magnet (PM) motors.

FR-F800 Series: Enhanced next-generation energy-saving inverter

  • Advanced optimum excitation control, which has been newly developed, provides a large starting torque while maintaining the motor efficiency under the conventional Optimum excitation control.
  • The tuning function enables operation of other manufacturers’ induction motors and PM motors, which increases the use in the energy saving applications.

FR-E800 Series: Compact, high functionality inverter

  • Deterministic performance of cyclic communication is maintained even when mixed with slower information data (non real-time). This enables TCP/IP communication devices to be used without affecting overall control.

FR-D700 Series: Simple and Compact inverter

  • Spring clamp terminals provide high reliability and easy wiring.
  • Shutoff circuit (hardware) securely provides emergency output shutoffs. The inverter with the safety stops function can comply with the safety standards without incurring too much cost.
  • Parameter writing/reading can be restricted with a 4-digit password.
