b8: Energy Saving
Energy-saving control improves overall system operating efficiency by operating the motor at its most efficient
level.
Set b8-01 and these parameters according to the control method and the motor.
• When you use V/f Control, set parameters b8-04 to b8-06 .
• When you use vector control with an induction motor, set parameters b8-02 and b8-03 .
• When you use a PM motor, set parameters b8-16 and b8-17 .
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. Make sure that you do Auto-Tuning and enter
the correct information about the motor before you use the Energy-saving control.
