Note:
If Speed Estimation is not working correctly even after adjusting b3-06, try using Current
Detection Speed Search instead.
■
b3-10: Speed Search Detection Compensation Gain
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).
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
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).
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
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).
