5.2 b: Application
♦ b7: Droop Control (CLV/PM)
Droop control automatically balances the load level between two motors driving the same load. Droop control must be
activated in one o f the drives controlling these motors. The drive in which Droop control is activated shifts the load from
one motor to another by automatically reducing the speed when the torque reference rises, and automatically increasing
the speed when the torque reference falls.
Note: D isable Inertia Com pensation (n5-01 = 0) w henever using D roop control.
■ b7-01: Droop Control Gain
Sets the amount o f speed reduction when the torque reference is 100%. The gain is set as a percentage o f the maximum
output speed. A setting o f 0.0% disables the Droop control function.
No. Parameter Name Setting Range Default
b7-01 Droop Control Gain 0.0 to 100.0% 0.0%

■ 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.
No. Parameter Name Setting Range Default
b7-02 Droop Control D elay Time 0.03 to 2.00 s 0.05 s
♦ 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 w ith a Yaskawa IPM motor.
■ b8-01: Energy Saving Control Selection
Enables or disables the Energy Saving function.
No. Parameter Name Setting Range Default
b8-01 Energy Saving Control Selection 0 or 1 0
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).
No. Name Setting Range Default
b8-16 Energy Saving Control Constant (Ki) 0.00 to 2.00 0.10
■ b8-17: Energy Saving Control Constant (Kt)
Enter the Energy Saving value (Kt) as specified on the motor nameplate (for IPM motors only).
No. Name Setting Range Default
b8-17 Energy Saving Control Constant (Kt) 0.00 to 2.00 1.00
