■ b7-01: Droop Control Gain
Sets the amount of speed reduction when the torque reference is 100%. The gain is set as a percentage of the maximum
output speed. A setting of 0.0% disables the Droop control function.

■ b7-02: Droop Control Delay Time
Adjusts the responsiveness of Droop control. Reduce the setting if the reaction time is too long, and increase it if hunting
occurs.
◆ b8: Energy Saving
The Energy Saving function can significantly increase the efficiency of an IPM motor.
Note: The Energy Saving function should be used only with a Yaskawa IPM motor.
■ b8-01: Energy Saving Control Selection
Enables or disables the Energy Saving function.
Setting 0: Disabled
Setting 1: Enabled
■ b8-16: Energy Saving Control Constant (Ki)
Enter the Energy Saving value (Ki) as specified on the motor nameplate (for IPM motors only).
■ b8-17: Energy Saving Control Constant (Kt)
Enter the Energy Saving value (Kt) as specified on the motor nameplate (for IPM motors only).
