To make adjustments, gradually decrease the setting value. If you decrease the setting value too much, speed search
will not operate correctly.

Set this parameter as a ratio of E2-03 [Motor No-Load Current]. The setting is a ratio with respect to 30% of the
motor rated current when E2-03 ≤ E2-01 [Motor Rated Current] × 0.3.
Note:
The setting is a ratio with respect to E9-06 [Motor Rated Current (FLA)] × 0.5 when A1-02 = 8 [Control Method Selection = EZOLV].

The Current Detection Speed Search gradually decreases the output frequency to search for the motor speed when the
output current is equal to or less than Speed Search Current Complete Level.
Set this parameter as a ratio of E2-03 [Motor No-Load Current]. The setting is a ratio with respect to 30% of the
motor rated current when E2-03 ≤ E2-01 [Motor Rated Current] × 0.3.
Note:
The setting is a ratio with respect to E9-06 [Motor Rated Current (FLA)] × 0.5 when A1-02 = 8 [Control Method Selection = EZOLV].

V/f CL-V/f OLV CLV AOLV
Sets the level to find the motor rotation direction. Increase the value if the drive cannot find the
direction.
V/f CL-V/f OLV CLV AOLV
Sets the conditions necessary to start Speed Search.
V/f CL-V/f OLV CLV AOLV
Sets the induced voltage for motors that use Speed Search. The drive will start Speed Search when
the motor induced voltage level is the same as the setting value. Usually it is not necessary to change
this setting.
V/f CL-V/f OLV CLV AOLV
Sets the current level that decreases the output current during Current Detection Speed Search.
V/f CL-V/f OLV CLV AOLV
Sets the current level that completes Speed Search.
