b3-10
(19AH)
Speed Search
Detection
Compensation Gain
(Speed Estimation)
Sets the gain which is applied to the speed detected by Speed Estimation
Speed Search before the motor is reaccelerated. Increase this setting if OV
occurs when performing Speed Search after a relatively long period of
baseblock.
Default: 1.05
Min: 1.00
Max: 1.20
b3-11
(19BH)
Speed Search
Method Switching
Level
(Speed Estimation)
Sets the switching level when the search method is automatically switched in
accordance with the size of the motor’s residual voltage.
Default:
Min: 0.5
Max: 100.0
b3-12
(19CH)
Current Detection
Dead-Band Width
during Speed Search
(Speed Estimation)
Sets the dead-band width for the current detected in a Speed Search.
Default: 8.0
Min: 2.0
Max: 20.0
b3-17
(1F0H)
Speed Search
Restart Current
Level
Sets the Speed Search restart current level as a percentage of the drive rated
current.
Default: 120%
Min: 0%
Max: 200%
b3-18
(1F1H)
Speed Search
Restart Detection
Time (Speed
Estimation)
Sets the time to detect Speed Search restart.
Default: 0.10 s
Min: 0.00 s
Max: 1.00 s
b3-19
(1F2H)
Number of Speed
Search Restarts
Sets the number of times the drive can attempt to restart when performing
Speed Search.
Default: 3
Min: 0
Max: 10
b3-25
(1C8H)
Speed Search Wait
Time
Sets the time the must wait between each Speed Search restart attempt.
Default: 0.5 s
Min: 0.0 s
Max: 30.0 s
b3-30
(30B0H)
Torque
Compensation Time
Constant during
Speed Search
Sets the primary delay time of the torque compensation function during
Speed Search, in ms units.
Default: 10 ms
Min: 0 ms
Max: 10000 ms
b3-31
(30B1H)
Current Suppression
Start Level during
Voltage Recovery
Sets the level at which to start the operation to extend the voltage recovery
time in order to suppress the current when the voltage is recovered during
Speed Search. The setting is made by assuming the motor no-load current is
1.0.
Default: 1.5
Min: 0.0
Max: 5.0
b3-32
(30B2H)
Current Suppression
Time Constant
during Voltage
Recovery
Sets the time constant to filter the level for extending the voltage recovery
time to suppress the current when the voltage is recovered during Speed
Search.
Default: 5 ms
Min: 0 ms
Max: 100 ms
b3-33
(30B3H)
Recovery Waiting
Time after Speed
Search Completion
Sets the waiting time between the end of Speed Search and the switch to
normal control. The frequency reference is maintained during this time.
Default: 0.01 s
Min: 0.00 s
Max: 5.00 s
b3-34
(30B4H)

Current Limit Value
1 during Speed
Search
Sets the current limit value of the software during Speed Search. Set as a
percentage of the motor rated current.
Default: 95.0%
Min: 0.0%
Max: 300.0%
b3-35
(30B5H)
Software CLA
Current Limit Value
2 during Speed
Search
