b3-04
(194H)
V/f Gain during Speed Search
(Speed Estimation type)
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.
Default:
<9>
Min: 10%
Max: 100%
195
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
196
b3-06
(196H)
Output Current 1 during Speed
Search (Speed Estimation Type)
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
196
b3-08
(198H)
Current Control Gain during Speed
Search (Speed Estimation Type)
Sets the proportional gain for the current controller during Speed Search.
There is normally no need to change this parameter from the default value.
Default:
<16>
Min: 0.00
Max: 6.00
196
b3-10
(19AH)
Speed Search Detection
Compensation Gain (Speed
Estimation Type)
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
196
b3-14
(19EH)
Bi-Directional Speed Search
Selection (Speed Estimation Type,
Speed Estimation 2 Type, Current
Detection 3 Type)
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
196
b3-17
(1F0H)
Speed Search Restart Current
Level (Speed Estimation Type)
Sets the Speed Search restart current level as a percentage of the drive rated current.
Default: 150%
Min: 0%
Max: 200%
196
b3-18
(1F1H)
Speed Search Restart Detection
Time (Speed Estimation Type)
Sets the time to detect Speed Search restart.
Default: 0.10 s
Min: 0.00 s
Max: 1.00 s
197
b3-19
(1F2H)
Number of Speed Search Restarts
(Speed Estimation Type)
Sets the number of times the drive can attempt to restart when performing Speed Search.
Default: 3
Min: 0
Max: 10
197
b3-24
(1C0H)
Speed Search Method Selection
1: Speed Estimation
2: Current Detection 2
3: Speed Estimation 2
4: Current Detection 3
Note: Settings 3 and 4 are available in the drive software versions S1017 and later.
Default:
<16>
Min:
<74>
Max:
<74>
197
b3-25
(1C8H)
Speed Search Wait Time (Speed
Estimation Type)
Sets the time the must wait between each Speed Search restart attempt.
Default: 0.5 s
Min: 0.0 s
Max: 30.0 s
197
b3-27
(1C9H)
Start Speed Search Select
Selects a condition to activate Speed Search Selection at Start (b3-01) or External Speed Search
Command 1 or 2 from the multi-function input.
0: Triggered when a Run command is issued (normal).
1: Triggered when an external baseblock is released.
Default: 0
Min: 0
Max: 1
197
b3-29
(77CH)
Speed Search Induced Voltage
Level
There is normally no need to change this parameter from the default value.
Performs Speed Search when the motor induced voltage exceeds the set level. If changes are
necessary, try lowering this value in small increments. If set too low, then the drive will not
perform Speed Search.
Default: 10%
Min: 0%
Max: 10%
198
b3-31
(BC0H)
Speed Search Operation Current
Level 1 (Current Detection 2)
Set the current level to use to limit the output current during a Speed Search.
Default: 1.50
Min: 1.50
Max: 3.50
198
b3-32
(BC1H)
Speed Search Operation Current
Level 2 (Current Detection 2)
Set the current level at which to end the Speed Search for Current Detection Type Speed Search
2.
Default: 1.20
Min: 0.00
Max: 1.49
