Sets the current level at which the speed is assumed to be
detected and Speed Search is ended. Set as a percentage of the
SpdSrch DeactCur 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
Search.
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
Search Delay delays executing Speed Search after a momentary power loss to
allow time for the contactor to close.
Sets the current injected to the motor at the beginning of Speed
Estimation Speed Search. Set as a coefficient for the motor rated
Srch Im Lvl1
current.
Sets the amount of output current during Speed Estimation
Speed Search as a coefficient for the no-load current.
Srch Im Lvl2
Sets the proportional gain for the current controller during Speed
Search.
Srch ACR P Gain
Sets the gain which is applied to the speed detected by Speed
Estimation Speed Search before the motor is reaccelerated.
Srch Detect Comp
Increase this setting if ov occurs when performing Speed Search
after a relatively long period of baseblock.
Sets the minimum current detection level during Speed Search. Default: 6.0
Srch I Deadband

Sets the Speed Search restart current level as a percentage of the
SrchRestart Lvl drive rated current.
Sets the time to detect Speed Search restart.
SrchRestart Time
Sets the number of times the drive can attempt to restart when
