Note:
• When you do Rotational Auto-Tuning, the drive will automatically set the energy-saving coefficient.
• The minimum values and the maximum values are different for different drive models.
–2011 to 2024, 4005 and 4008: 0.0 - 2000.0

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.

The Search Operation changes the output voltage in small increments to find a setpoint at which the drive can use
minimum power to operate.
Set this parameter to 0 to disable Search Operation. This will not disable Energy-saving control.
If the setting value is too low, the motor will stall when loads suddenly increase.

Note:
• If low inertia causes vibration in the machine, increase the setting value in 10 Hz increments and check the response. If A1-02 = 8 [Control
Method Selection = EZOLV], increase the setting value in 1 Hz increments.
• To make the motor more efficient, decrease the setting value in 1 Hz increments until the point immediately before machine vibration starts
to occur.

An increase in the value can make the operational efficiency better. However, if the load inertia is small, it may be
necessary to adjust the value to prevent machine vibration.
Note:
• If low inertia causes vibration in the machine, decrease the setting value in 1.0-degree increments and check the response.
• To make the motor more efficient, increase the setting value in 1.0-degreee increments until the point immediately before machine vibration
starts to occur.

V/f OLV/PM EZOLV OLV/PM
Sets the time constant to measure output power.
V/f OLV/PM EZOLV OLV/PM
Sets the voltage limit for Search Operation as a percentage of the motor rated voltage.
V/f OLV/PM EZOLV OLV/PM
Sets the frequency of Energy-saving control search operations. Usually it is not necessary to change
this setting.
V/f OLV/PM OLV/PM EZOLV
Sets the amplitude of Energy-saving control search operations.
