YASKAWA GA700 Technical Manual page 611

This setting starts operating the drive at the minimum output frequency when the Run command is entered.
The drive will execute Speed Search and begin operating the motor when the Run command is enabled while the
External Speed Search command 1 or 2 [H1-xx = 61, 62] is input from a multi-function input terminal.
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
No.
Name
(Hex.)
b3-02 Speed Search
Deactivation Current Sets the current level that ends Speed Search as a percentage of the drive
(0192)
Lower this setting if the drive is unable to restart the motor.
■
b3-03: Speed Search Deceleration Time
No.
Name
(Hex.)
b3-03 Speed Search
Deceleration Time
(0193)
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:
Lower the value set in b3-03 if oL1 [Motor Overload] is triggered when executing Current Detection Speed Search.
■
b3-04: V/f Gain during Speed Search
No.
Name
(Hex.)
b3-04 V/f Gain during
Speed Search
(0194)
Use the following expression to calculate the output voltage during speed searches.
Output voltage during speed searches = Configured V/f × b3-04
This configuration is unnecessary if the current detection search operates correctly.
■
b3-05: Speed Search Delay Time
No.
Name
(Hex.)
b3-05 Speed Search Delay
Time
(0195)
In cases where a magnetic contactor is used between the drive and the motor, the contactor must be closed before
the drive can perform Speed Search. This parameter sets a delay time to activate the magnetic contactor in such
cases.

b3-06: Speed Estimation Current Level 1
No.

V/f CL-V/f OLV CLV AOLV
rated output current. Normally there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Determines the deceleration time during Speed Search operation. Set the
time it takes to decelerate from the maximum output frequency to the
minimum output frequency.
V/f CL-V/f OLV CLV AOLV
Configures the ratio used to reduce the V/f during searches to reduce the
output current during speed searches.
V/f CL-V/f OLV CLV AOLV
If a magnetic contactor is installed between the drive and the motor, this
parameter sets a delay time to activate the magnetic contactor by delaying
Speed Search.
V/f CL-V/f OLV CLV AOLV
Configure the amount of current that flows to the motor as a coefficient of
the motor rated current when executing the Speed Estimation Speed Search.
Normally there is no need to change this setting.
