Sets output frequency reduction time during Speed Search.
SpdSrch Dec Time
Determines how much to lower the V/f ratio during Speed
Search.
Output voltage during Speed Search equals the V/f setting
multiplied by b3-04.
Note:
SpdSrch V/f
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
Note:
Sets the proportional gain for the current controller to adjust
responsiveness during Speed Estimation Speed Search.
Srch ACR P Gain
There is normally no need to change this parameter from the
default setting.
Sets the integral time for the current controller during to adjust
responsiveness during Speed Estimation Speed Search.
Srch ACR I Time
There is normally no need to change this parameter from the
default value.
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.
Srch I Deadband
Note:
Bidir Search Sel 0: Disabled (uses the direction of the frequency reference)
0: Disabled 1: Enabled (drive detects which way the motor is rotating)
1: Enabled
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
Num of SrchRestr performing Speed Search.
SpdSrch Method 0: Current Detection
0: CurrentDetection 1: Speed Estimation
1: Speed Estimation
Sets the time the drive must wait between each Speed Search
restart attempt.
Sets the level that determines the direction of motor rotation.
