b2-09
Motor Pre-Heat
Current 2
Determines the percentage of motor rated
output current used for the motor pre-heat
function.
b3-01
Speed Search Selection
at Start
0: Disabled
1: Enabled
Note:
Default setting is dependent upon
parameter A1-02, Control Method
Selection.
b3-02
Speed Search
Deactivation Current
Sets the current level at which the speed is
assumed to be detected and Speed Search is
ended. Set as a percentage of the drive rated
current.
b3-03
Speed Search
Deceleration Time
Sets output frequency reduction time during
Speed Search.
b3-04
