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.
V/f V/f V/f w PG
OLV/PM AOLV/PM
Sets output frequency reduction time during Speed Search.
V/f V/f V/f w PG V/f w PG
OLV/PM AOLV/PM
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.
All Modes
When using an external contactor on the output side, b3-05 delays executing
Speed Search after a momentary power loss to allow time for the contactor to
close.
V/f V/f V/f w PG V/f w PG
OLV/PM AOLV/PM
Sets the current injected to the motor at the beginning of Speed Estimation
Speed Search. Set as a coefficient for the motor rated current.
V/f V/f V/f w PG
OLV/PM AOLV/PM
Sets the gain which is applied to the speed detected by Speed Estimation Speed
Search before the motor is reaccelerated. Increase this setting if ov occurs
when performing Speed Search after a relatively long period of baseblock.
