2.2 b: Application
b3-02: Speed Search Deactivation Current
■
Sets the operating current for Speed Search as a percentage of the drive rated current. Normally there is no need to
change this setting. If the drive has trouble restarting, try lowering this value.
No.
b3-02
<1> For details on the default settings, refer to
b3-03: Speed Search Deceleration Time
■
Parameter b3-03 sets the output frequency reduction ramp. The time entered into b3-03 will be the time to decelerate
from maximum frequency (E1-04) to minimum frequency (E1-09).
No.
b3-03
b3-04: V/f Gain during Speed Search
■
During Speed Search, the output voltage calculated from the V/f pattern is multiplied by the value set in parameter b3-04.
Changing this setting can be useful in order to reduce the output current during Speed Search.
No.
b3-04
<1> For details on the default settings, refer to
b3-05 Speed Search Delay Time (Speed Estimation)
■
In cases where an output contactor is used between the drive and the motor, the contactor must be closed before Speed
Search can be performed. This parameter can be used to delay the Speed Search operation, giving the contactor enough
time to close completely.
No.
b3-05
■ b3-06: Output Current 1 during Speed Search (Speed Estimation)
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 (E4-01 for motor 2). 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
<1> For details on the default settings, refer to
Note: If Speed Estimation is not working correctly even after adjusting b3-06, try using the Current Injection step in Speed Estimation
Speed Search instead. For details, refer to
