Automatic Energy-saving Operation Function
• This function automatically adjusts the inverter output power during constant speed operation to the
minimum level.
It is suitable for fan, pump, or other load that has reduced torque characteristics.

A086 Response/Accuracy
Adjustment
• To perform energy-saving operation using this function, set the Operation Mode Selection (A085) to
01 (Energy-saving operation).
You can adjust the response and accuracy of the function in the Energy-saving Response/Accuracy
Adjustment (A086).
• Because this function controls the output power moderately, it may cause the motor to stall if a rapid
load variation such as an impact load occurs, which may result in an overcurrent trip.

Automatic Optimum Acceleration/Deceleration
• The automatic acceleration/deceleration function eliminates the need for acceleration/deceleration
settings for Inverter operation.
• To use this function, set the Operation Mode Selection (A085) to 02 (Automatic operation).
• Although, conventionally, the user had to set an inverter acceleration/deceleration time depending on
the load conditions etc., this function can automatically adjust the acceleration/deceleration time to
make full use of the inverter's capacity.
• The acceleration time is the time during which the motor accelerates at the current value within the
setting in the Overload Limit Level (b022) if the overload limit function is enabled, or at approximately
150% or less of the rated current of the inverter if the overload limit function is disabled, respectively.
• The deceleration time is the time during which the motor decelerates at a current value of
approximately 150% or less, or at a DC voltage of 370 V or less (for 200-V class) or at 740 V or less
(for 400-V class) in the inverter.
• To ensure stable operation, set the Overload Limit Level (b022) to 150% of the rated current of your
motor.
Thus, the function automatically sets the acceleration/deceleration time by responding in real time to
changes in the load and inertia.
