12.2 b: APPLICATION
SIEPCYEUOQ2V01A Q2V Technical Manual 461
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.

Speed Curr Lev1 for
Estimation
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.
Determined by o2-04
(0.0 - 2.0)
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.
Note:
When the drive cannot accurately estimate the speed after you adjust this parameter, use Current Detection Speed Search.

Speed Curr Lev2 for
Estimation
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.
1.0
(0.0 - 3.0)
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.

Speed ACR PGain for
Estimation
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.

Speed ACR ITime for
Estimation
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.

Speed Det Gain for
Estimation
Sets the gain to correct estimated frequencies from Speed Estimation Speed Search.
1.05
(1.00 - 1.20)
If the drive detects ov [DC Bus Overvoltage] when you restart the motor, increase the setting value.
■ b3-14: Speed Bi-Directional Search
No.

Speed Bi-Directional
Search
Sets the direction of Speed Search to the direction of the frequency reference or in the motor
rotation direction as detected by the drive.
