2 : Automatic Optimization
Note:
Setting 2 is available only when A1-02 = 6, 7 [Control Method Selection = AOLV/PM, CLV/PM] and in Expert Mode.

(01CF)
Expert
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
No.

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.
