V/f V/f w/PG
OLV/PM AOLV/PM
0: Disabled
1: Enabled
V/f V/f w/PG
OLV/PM AOLV/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 w/PG
OLV/PM AOLV/PM
Sets output frequency reduction time during Speed Search.
V/f 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.
Note: Available control mode for parameter b3-04 varies by drive model:
CIMR-A2A0004 to 2A0415 and 4A0002 to 4A0675: Available when A1-02 = 0
CIMR-A4A0930 and 4A1200: Available when A1-02 = 0, 2
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 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 w/PG
OLV/PM AOLV/PM
Sets the amount of output current during Speed Estimation Speed Search as a coefficient for the
no-load current.
Note: This parameter is available in models CIMR-A4A0930 and 4A1200.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the proportional gain for the current controller to adjust responsiveness during Speed
Estimate Speed Search.
There is normally no need to change this parameter from the default value.
V/f V/f w/PG
OLV/PM AOLV/PM
There is normally no need to change this parameter from the default value.
Sets the integral time for the current controller during to adjust responsiveness during Speed
Estimation Speed Search.
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.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the minimum current detection level during Speed Search.
Note: This parameter is available in models CIMR-A4A0930 and 4A1200.
V/f V/f w/PG
OLV/PM AOLV/PM
0: Disabled (uses the direction of the frequency reference)
1: Enabled (drive detects which way the motor is rotating)
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the Speed Search restart current level as a percentage of the drive rated current.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time to detect Speed Search restart.
