460 SIEPCYEUOQ2V01A Q2V Technical Manual
Set L5-01 [Auto-Reset Attempts] = 1 or more. After there is an Auto Restart fault, the drive automatically does
Speed Search.
• Do Speed Search after Momentary Power Loss
Set L2-01 =1 [RideThru@PwrLoss = Enabled], and set L2-50 = 0, 1 [RidThruMode@PwrLoss = Timer
Controlled, While CPU Active].
• Do Speed Search after You Clear the External Baseblock Command
After you clear the external baseblock command, enable the Run command, and when the output frequency is
higher than the minimum frequency, the drive does Speed Search.
■ b3-01: SpSrch@Start Selection

(0191)
SpSrch@Start Selection
Sets the Speed Search at Start function where the drive will perform Speed Search with each Run
command.
Determined by A1-02
(0, 1)
0 : Disabled
Enter a Run command to start to operate the drive at the minimum output frequency.
When the Run command is enabled and the Speed Search from Fmax or Fref [H1-xx = 67, 68] is input from a
multi-function input terminal, the drive will do Speed Search and start to operate the motor.
1 : Enabled
Enter the Run command to do Speed Search. The drive completes Speed Search then starts to operate the motor.
■ b3-02: SpSrch Deactivation Current
No.
(Hex.)
Name Description

(0192)
SpSrch Deactivation
Current
Sets the current level that stops Speed Search as a percentage of the drive rated output current.
Usually it is not necessary to change this setting.
Determined by A1-02
(0 - 200%)
If the drive cannot restart the motor, decrease this setting.
■ b3-03: SpSrch Deceleration Time
No.
(Hex.)
Name Description
Default
(Range)
b3-03
(0193)
SpSrch Deceleration Time
Sets the deceleration time during Speed Search operation. Set the length of time to decelerate
from the maximum output frequency to the minimum output frequency.
2.0 s
(0.1 - 10.0 s)
This is the output frequency deceleration time used by Current Detection Speed Search and by the Current
Injection Method of Speed Estimation Speed Search.
Note:
• When A1-02 = 8 [Control Method = EZ Vector], this parameter takes effect only in Expert Mode.
• If the drive detects oL1 [Motor Overload] during Current Detection Speed Search, decrease the value set in b3-03.
■ b3-04: SpSrch V/F Gain
No.
(Hex.)
Name Description
Default
(Range)
b3-04
(0194)
SpSrch V/F Gain
Sets the ratio used to reduce the V/f during searches to reduce the output current during speed
searches.
Determined by o2-04
(10 - 100)
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.
(Hex.)
Name Description
Default
(Range)
b3-05
(0195)
SpSrch Delay Time
Sets the Speed Search delay time to activate a magnetic contactor installed between the drive and
motor.
0.2 s
(0.0 - 100.0 s)
