(0194)
V/f Gain during Speed
Search
SpdSrch V/f
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:
Models 2A0004 to 2A0415, 4A0002 to 4A0675,
and 5A0003 to 5A0242:
Available when A1-02 = 0
Models 4A0930 and 4A1200: Available when
A1-02 = 0, 2
Default: <2>
Min.: 10%
Max.: 100%

Speed Search Delay
Time
Search Delay
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
Max.: 100.0

Output Current 1 during
Speed Search
Srch Im Lvl1
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: <2>
Min.: 0.0
Max.: 2.0

Compensation Gain
Srch Detect Comp
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
