No.
b3-05
b3-06: Output Current 1 During Speed Search
n
Sets the current injected to the motor at the beginning of Estimation Type Speed Search as a factor related to motor rated
current set in E2-01 and E4-01. If the motor speed is relatively slow when the drive starts to perform Speed Search after a long
period of baseblock, it may be helpful to increase the setting value. The output current during Speed Search is automatically
limited by the drive rated current. This function has no influence when Current Detection Speed Search is used (b3-24 = 0).
No.
b3-06
Note: If Speed Estimation is not working correctly even after adjusting b3-06, try using Current Detection Speed Search instead.
b3-08: Current Control Gain during Speed Search (Speed Estimation Type)
n
Sets the proportional gain for the current controller during Speed Search. There is normally no need to change this parameter
from the default value.
No.
b3-08
b3-10: Speed Search Detection Compensation Gain
n
This parameter sets the gain for the detected motor speed of the Speed Estimation Speed Search. The drive will start the motor
at the estimated speed multiplied by b3-10. The setting should be increased if an overvoltage fault occurs when the drive
restarts the motor. This function has no influence when Current Detection Speed Search is used (b3-24 = 0).
No.
b3-10
Note:
Increase this value if overvoltage occurs when performing Speed Search at start after a relatively long period of baseblock.
b3-14: Bi-Directional Speed Search Selection
n
Sets how the drive determines the motor rotation direction when performing Speed Estimation Speed Search. The setting has
no influence on Current Detection Speed Search (b3-24 = 0).
No.
b3-14
Setting 0: Disabled
The drive uses the frequency reference to determine the direction of motor rotation in order to restart the motor.
Setting 1: Enabled
The drive detects the motor rotation direction in order to restart the motor.
b3-17: Speed Search Restart Current Level
n
If there is a fairly large difference between the estimated frequency and the actual motor speed when performing Speed
Estimation, a large current can flow. This parameter sets the current level at which Speed Estimation is restarted, thus avoiding
overcurrent and overvoltage problems. The parameter is set as a percentage of the drive rated current. This function has no
influence when Current Detection Speed Search is used (b3-24 = 0).
No.
b3-17
b3-18: Speed Search Restart Detection Time
n
Sets the time the current must be above the level set in b3-17 before Speed Search is restarted. This function has no influence
when Current Detection Speed Search is used (b3-24 = 0)
No.
