b
Output Current 1 durin Speed Searc (Speed Estimation ype)
Sets the current injected to the motor at the beginning of Speed Estimation Speed Search as a factor of the motor rated current
set in E2-01. 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.
No
b3-06
Use Current Detection Speed Search if Speed Estimation is not working correctly even after adjusting b3-06.
Note:
b
7 Output Current 2 durin Speed Searc (Speed Estimation ype)
Sets the amount of output current during Speed Estimation Speed Search as a coefficient for the no-load current (output current
during Speed Search is automatically limited by the drive rated current).
Increase this setting value in increments of 0.1 if the drive fails to perform Speed Estimation.

Speed Searc Detection Compensation Gain (Speed Estimation ype)
Sets the gain for the detected motor speed of the Speed Estimation Speed Search. Increase the setting only if an overvoltage
fault occurs when the drive restarts the motor.
No

b 11 Speed Searc Met od S itc in Le el (Speed Estimation ype)
Within the type of the speed measurement, the search method can be switched automatically by the amount of remaining
voltage in the motor. This parameter sets the switching level. (200 V class at 100% = 200 V, and 400 V class at 100% = 400
V).

Sets the minimum current detection level during Speed Search. Increase this setting value in increments of 0.1 if the drive
fails to perform Speed Estimation.
