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.
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.
Note:
Enabling the Energy Saving function when using a PM motor may adversely affect motor efficiency depending on the type of PM motor.
Disable the Energy Saving function in such cases.

b8-02: Energy Saving Gain (OLV, CLV)
Sets the gain level for Energy Saving. A higher value results in lower magnetization of the motor and less energy consumption.
If the value is set too high the motor may stall.
