Note:
• If the machine vibrates due to low inertia, increase the setting value in increments of 10 Hz while checking the responsiveness. If A1-
02 = 8 [Control Method Selection = EZ Open Loop Vector Control], increase the setting value in increments of 1 Hz.
• To improve motor efficiency, reduce the setting value in increments of 1 Hz until the point just before machine vibration begins to
occur.

Increasing the value may improve operational efficiency. However, adjustment may be necessary to prevent
machine vibration if the load inertia is small.
Note:
• If the machine vibrates due to low inertia, reduce the setting value in increments of 1.0 degrees while checking the responsiveness.
• To improve motor efficiency, increase the setting value in increments of 1.0 degrees until the point just before machine vibration begins
to occur.

When the value of C5-01 [ASR Proportional Gain 1] is reduced, make sure to also reduce the value of b8-21 to
maintain the correct ratio.

V/f CL-V/f OLV CLV AOLV
Configures the d-axis current reference filter time constant.
V/f CL-V/f OLV CLV AOLV
Configures the energy-saving control search operation frequency. Normally
there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Configures the amplitude of energy-saving control search operations.
V/f CL-V/f OLV CLV AOLV
Configures the gain of search operations.
V/f CL-V/f OLV CLV AOLV
Configures the frequency of the filter used to extract the high-efficiency
phase from search operations. Normally there is no need to change this
setting.
V/f CL-V/f OLV CLV AOLV
Configures the limit value of search operation output. Normally there is no
need to change this setting.
