Energy-saving control improves overall system operating efficiency by operating the motor at its most efficient level.

Set b8-01 and the following parameters according to the control mode and the motor.

  • Set parameters b8-04, b8-05, and b8-06 when using V/f Control or Closed Loop V/f Control.

  • Set parameters b8-02, b8-03 when using vector control with an induction motor.

  • Set parameters b8-16, b8-17 when using a PM motor.

Note:

  • Energy-saving control is not appropriate for applications with sudden changes in the load, or applications driving heavy loads such as a traverse car application.

  • Energy-saving control maximizes operation based on precise motor data set to the drive. Be sure to perform Auto-Tuning and enter the correct information about the motor before using the Energy-saving control.
