1 2 b Application
b 1 Bi Directional Speed Searc Selection (Speed Estimation ype)
Sets how the drive determines the motor rotation direction when performing Speed Estimation Speed Search.
No
b3-14
Settin Disabled
The drive uses the frequency reference to determine the direction of motor rotation to restart the motor.
Settin 1 Enabled
The drive detects the motor rotation direction to restart the motor.
b 17 Speed Searc
Sets the current level at which Speed Estimation is restarted as a percentage of drive rated current to avoid overcurrent and
overvoltage problems since a large current can flow into the drive if the difference between the estimated frequency and the
actual motor speed is too big when performing Speed Estimation.
No
b3-17
b 18 Speed Searc
Sets the time for which the current must be above the level set in b3-17 before restarting Speed Search.
No
b3-18
b 1 Number o Speed Searc
Sets the number of times the drive should attempt to find the speed and restart the motor. If the number of restart attempts
exceeds the value set to b3-19, the SEr fault will occur and the drive will stop.
No
b3-19
b 2 Speed Searc Met od Selection
Sets the Speed Search method.
No

Settin 1 Speed Estimation
Note: Refer to Current Detection Speed Search (b3-24 = 0) on page 31
for explanations of the Speed Search methods.

b 2 Speed Searc
Sets the wait time between Speed Search restarts. Increase the wait time if problems occur with overcurrent, overvoltage, or
if the SEr fault occurs.
No
