Energy Saving Gain
Sets the gain for Energy-saving control.
Determined by A1-02
(0.0 - 10.0)
Increase the setting value to increase energy saving. If the setting value is too large, the motor will stall.

Energy Saving Filter Time
Sets the responsiveness for Energy-saving control.
Determined by A1-02，C6-

(0.00 - 10.00 s)
Decrease the setting value to increase responsiveness. If the setting value is too low, operation will not be stable.

Energy Saving Coefficient
Value
Sets the Energy-saving control coefficient to maintain maximum motor efficiency. The default setting
is for Yaskawa motors.
Determined by C6-01, E2-
11, and o2-04
(0.00 - 655.00)
When you use a motor from a different manufacturer, increase the setting value in 5% increments to find the
minimum value for U1-08 [Output Power] at light loads.
When you decrease the setting value, it decreases the output voltage and decreases power consumption. If the setting
value is too low, the motor will stall.
Note:
When you do Rotational Auto-Tuning, the drive will automatically set the energy-saving coefficient.
■ b8-05: Power Detection Filter Time

Power Detection Filter Time
Sets the time constant to measure output power.
20 ms
(0 - 2000 ms)
Decrease the setting value to increase responsiveness to load changes. If you set the value too low during operation at
light loads, motor speed is not stable.
