SpdSrch at Start 0: Disabled

1: Enabled
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 (output
current during Speed Search is automatically limited by the
Srch Im Lvl2
drive rated current).
Increase this setting value in increments of 0.1 if the drive fails
to perform Speed Estimation.
Sets the proportional gain for the current controller during
Speed Search.
Srch ACR P Gain
Sets the Integral Time for the current controller during Speed
Search.
Srch ACR I Time
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.
Uses the amount of voltage remaining in the motor to
automatically switch the search method within the type of speed
Srch Mthd Sw Lvl measurement.
(200 V class at 100% = 200 V;
400 V class at 100% = 400 V)
Sets the minimum current detection level during Speed Search.
Increase this setting value in increments of 0.1 if the drive fails
Srch I Deadband
to perform Speed Estimation.
