b3-01
<1> Refer to Control Mode Dependent Parameter Default Values on page 84
Setting 0: Disabled
This setting starts operating the drive at the minimum output frequency when the Run command is entered. If external
Speed Search 1 or 2 is already enabled by a contact input, the drive will start operating with Speed Search.
Setting 1: Enabled
This setting performs Speed Search when the Run command is entered. The drive begins running the motor after Speed
Search is complete.
b3-02: Speed Search Deactivation Current
n
Sets the operating current for Speed Search as a percentage of the drive rated current. Normally there is no need to
change this setting. Lower this value if the drive has trouble restarting.
No.

<1> Refer to Control Mode Dependent Parameter Default Values on page 84
b3-03: Speed Search Deceleration Time
n
Parameter b3-03 sets the output frequency reduction ramp. The time entered into b3-03 will be the time to decelerate
from maximum frequency (E1-04) to minimum frequency (E1-09).
No.
b3-03
b3-04: V/f Gain during Speed Search
n
During Speed Search, the output voltage calculated from the V/f pattern is multiplied by this value. Changing this value
can help reduce the output current during Speed Search.
No.
b3-04
<1> Refer to Defaults by Drive Model Selection (o2-04) on page 87
Note: OLV (A1-02 = 2) is available from the drive software version S0102 and later.
b3-05: Speed Search Delay Time (Speed Estimation)
n
In cases where an output contactor is used between the drive and the motor, the contactor must be closed before Speed
Search can be performed. This parameter can be used to delay the Speed Search operation, giving the contactor enough
time to close completely.
No.
