If there is not sufficient residual voltage, then the drive will inject DC current into the motor to estimate the motor
speed.

SpSrch Wait Time
Sets the length of time the drive will wait to start the Speed Search Retry function.
0.5 s
(0.0 - 30.0 s)
If the drive detects these faults during speed search, increase the setting value:
•
oC [Overcurrent]
•
ov [Overvoltage]
•
SEr [Speed Search Retries Exceeded]

SpSrch BackEMF
Threshold
Sets the induced voltage for motors that use Speed Search. The drive will start Speed Search
when the motor induced voltage level is the same as the setting value. Usually it is not necessary
to change this setting.
10%
(0 - 10%)
To make adjustments, gradually decrease the setting value. If you decrease the setting value too much, speed
search will not operate correctly.

SpSrch I Ref Level
Sets the current level that decreases the output current during Current Detection Speed Search.
1.50
(1.50 - 3.50)
Set this parameter as a ratio of
E2-03 [Mot No-Load Current]
. The setting is a ratio with respect to 30% of the
motor rated current when
E2-03
≤
E2-01 [Mot Rated Current (FLA)]
× 0.3.
Note:
The setting is a ratio with respect to
E9-06 [Motor Rated Current]
× 0.5 when
A1-02 = 8 [Control Method = EZ Vector]
.

SpSrch I End Level
Sets the current level that completes Speed Search.
1.20
(0.00 - 1.49)
The Current Detection Speed Search gradually decreases the output frequency to search for the motor speed when
the output current is equal to or less than Speed Search Current Complete Level.
Set this parameter as a ratio of
E2-03 [Mot No-Load Current]
. The setting is a ratio with respect to 30% of the
motor rated current when
E2-03
≤
E2-01 [Mot Rated Current (FLA)]
× 0.3.
Note:
The setting is a ratio with respect to
E9-06 [Motor Rated Current]
× 0.5 when
