b8: Energy Saving

The Energy Saving feature improves overall system operating efficiency by operating the motor at its most efficient level.
Note: 1. Energy Saving is not designed for applications that experience instantaneous heavy loads or applications that rarely operate with light
load conditions.
2. Energy Saving is designed for applications with variable torque (Normal Duty) and is not appropriate for applications where the load
may suddenly increase.
3. The performance of the Energy Saving function depends on the accuracy of the motor data. Always perform Auto-Tuning and correctly
enter the motor data before using this function.
n b8-01: Energy Saving Control Selection
Enables or disables the Energy Saving function.
No.

Setting 0: Disabled
Setting 1: Enabled
n b8-04: Energy Saving Coefficient Value
Determines the level of maximum motor efficiency. Setting range is 0.0 to 2000.0 for drives 3.7 kW and smaller. The display
resolution depends on the rated output power of the drive.
No.

Note: The default value changes if the motor rated capacity set to E2-11 is changed. The Energy Saving coefficient is set automatically when
Auto-Tuning for Energy Saving is performed
