0: Disabled
1: Enabled
Default:
<10>
Min: 0
Max: 1
163
b3-02
(192H)

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.
Default:
<10>
Min: 0%
Max: 200%
163
b3-03
(193H)
Speed Search Deceleration Time
Sets output frequency reduction time during Speed Search.
Default: 2.0 s
Min: 0.1 s
Max: 10.0 s
163
b3-04
(194H)
V/f Gain during Speed Search
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-A2A0004 to 2A0415 and 4A0002 to 4A0675: Available when A1-02 = 0
CIMR-A4A0930 and 4A1200: Available when A1-02 = 0, 2
Default:
<9>
Min: 10%
Max: 100%
164
b3-05
(195H)
Speed Search Delay Time
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.
Default: 0.2 s
Min: 0.0 s
Max: 100.0 s
164
b3-06
(196H)
Output Current 1 during Speed
Search
Sets the current injected to the motor at the beginning of Speed Estimation Speed Search. Set as
a coefficient for the motor rated current.
Default:
<9>
Min: 0.0
Max: 2.0
164
b3-07
(197H)
Output Current 2 during Speed
Search (Speed Estimation Type)
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-A4A0930 and 4A1200.
Default:
<9>
Min: 0.0
Max: 5.0
164
b3-08
(198H)
Current Control Gain during Speed
Search (Speed Estimation Type)
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.
Default:
<16>
Min: 0.00
Max: 6.00
164
b3-09
(199H)
Current Control Integral Time
during Speed Search (Speed
Estimation Type)
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.
Default:
<10>
Min: 0.0 ms
Max: 1000.0 ms
164
b3-10
(19AH)
Speed Search Detection
Compensation Gain
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.
Default: 1.05
Min: 1.00
Max: 1.20
165
b3-12
(19CH)
Minimum Current Detection Level
during Speed Search
Sets the minimum current detection level during Speed Search.
Note: This parameter is available in models CIMR-A4A0930 and 4A1200.
Default: 6.0
Min: 2.0
Max: 10.0
165
b3-14
(19EH)
Bi-Directional Speed Search
Selection
0: Disabled (uses the direction of the frequency reference)
1: Enabled (drive detects which way the motor is rotating)
Default:
<10>
Min: 0
Max: 1
165
b3-17
(1F0H)
Speed Search Restart Current
Level
