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.
Sets output frequency reduction time during Speed Search.
SpdSrch Dec Time
Determines how much to lower the V/f ratio during Speed

SpdSrch V/f
Output voltage during Speed Search equals the V/f setting
multiplied by b3-04.
When using an external contactor on the output side, b3-05
