V/f V/f V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/PM
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 OLV
OLV/PM AOLV/PM CLV/PM
Sets output frequency reduction time during Speed Search.
V/f V/f V/f w PG V/f w PG OLV
OLV/PM AOLV/PM CLV/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.
Note: Available control mode for parameter b3-04 varies by drive
model:
CIMR-Ao2A0004 to 2A0415, 4A0002 to 4A0675, and
5A0003 to 5A0242: Available when A1-02 = 0, 1
CIMR-Ao4A0930 and 4A1200: Available when A1-02 = 0
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 OLV
OLV/PM AOLV/PM CLV/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 OLV
OLV/PM AOLV/PM CLV/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.
V/f V/f V/f w PG V/f w PG OLV OLV

0: Disabled (uses the direction of the frequency reference)
1: Enabled (drive detects which way the motor is rotating)
V/f V/f V/f w PG OLV OLV

Sets the Speed Search restart current level as a percentage of the drive rated
current.
V/f V/f V/f w PG OLV OLV

Sets the number of times the drive can attempt to restart when performing
Speed Search.
