Inverters-FREQROL-F Series　-FREQROL-F700PJ- Inverter Control for Energy Saving

Energy saving with speed control

  • The consumed power of a variable-torque load, such as fans, pumps, and blowers, is proportional to the cube of its rotation speed.
    This means that controlling the rotation speed to adjust the air volume can lead to energy saving.

*1Rated motor output is 100%.

Energy saving with Optimum excitation control (General-purpose motors)

The optimum excitation control achieves the highest motor efficiency.
Further energy saving can be achieved for applications such as fans and pumps with variable load torque.

Check the energy saving effect at a glance

  • Energy saving monitor is available. The energy saving effect can be checked using an operation panel, output terminal (terminal FM), or network.
  • The output power amount measured by the inverter can be output in pulses. The cumulative power amount can be easily checked.*4
