Estimation Speed Search. Also adjusts speed search responsiveness. Usually
it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain to correct estimated frequencies from Speed Estimation Speed
Search.
V/f CL-V/f OLV CLV AOLV
Sets the direction of Speed Search to the direction of the frequency
reference or in the motor rotation direction as detected by the drive.
V/f CL-V/f OLV CLV AOLV
Sets the current level for the search retry function in Speed Estimation
Speed Search as a percentage where drive rated current is a setting value of
100%.
V/f CL-V/f OLV CLV AOLV
Sets the length of time that the drive will wait to retry Speed Estimation
Speed Search when too much current flow stopped the Speed Search.
V/f CL-V/f OLV CLV AOLV
Sets the number of times to restart Speed Search if Speed Search does not
