12.2 b: APPLICATION
b3-04 SpSrch V/F Gain
No.
Name
(Hex.)
b3-04
SpSrch V/F Gain
(0194)
Use the this formula to calculate the output voltage during Speed Search:
Output voltage during Speed Search = Configured V/f × b3-04
When the current detection search operates correctly, this configuration is not necessary.
b3-05 SpSrch Delay Time
No.
Name
(Hex.)
b3-05
SpSrch Delay Time
(0195)
When you use a magnetic contactor between the drive and motor, you must close the contactor before the drive
will do Speed Search. This parameter sets a delay time to activate the magnetic contactor.
b3-06 Speed Curr Lev1 for Estimation
No.
Name
(Hex.)
b3-06
Speed Curr Lev1 for
Estimation
(0196)
Expert
When the speed estimation value is the minimum output frequency, increase this setting. You can do this when the
motor coasts at a high speed while the drive estimates the speed during Speed Estimation Speed Search. The limit
of the output current during speed search is automatically the drive rated current.
When the drive cannot accurately estimate the speed after you adjust this parameter, use Current Detection Speed
Search.
b3-07 Speed Curr Lev2 for Estimation
No.
Name
(Hex.)
b3-07
Speed Curr Lev2 for
Estimation
(0197)
Expert
During Speed Estimation Speed Searches, when the speed estimation value aligns with the minimum output
frequency, increase the setting value in 0.1-unit increments. The limit of the output current during speed search is
automatically the drive rated current.

Sets the ratio used to reduce the V/f during searches to reduce the output current during speed
searches.
V/f

OLV
CLV
AOLV
Sets the Speed Search delay time to activate a magnetic contactor installed between the drive and
motor.
V/f
CL-V/f
OLV
CLV
AOLV
Sets the level of current that flows to the motor during Speed Estimation Speed Search as a
coefficient of the motor rated current. Usually it is not necessary to change this setting.
V/f
CL-V/f
OLV
CLV
AOLV
Sets the level of current that flows to the motor during Speed Estimation Speed Search as a
coefficient of E2-03 [Mot No-Load Current] or E4-03 [M2 No-Load Current]. Usually it is not
necessary to change this setting.
V/f
CL-V/f
OLV
CLV
AOLV
Sets the proportional gain for the automatic current regulator during Speed Estimation Speed
Search. Also adjusts speed search responsiveness. Usually it is not necessary to change this
setting.
V/f
CL-V/f
OLV
CLV
AOLV
Sets the integral time for the automatic current regulator during Speed Estimation Speed Search.
Also adjusts speed search responsiveness. Usually it is not necessary to change this setting.
