Description
V/f CL-V/f OLV CLV AOLV
Sets the Speed Search method when you start the motor or when you restore power after
a momentary power loss.
Note:
• When A1-02 = 8 [Control Method Selection = EZOLV], the default setting
changes when the setting for E9-01 [Motor Type Selection] and the drive model
change.
–E9-01 = 0 [Induction (IM)]
–2004 to 2313, 4002 to 4296: 1
–2360, 2415, 4371 to 4675: 2
–E9-01 = 1, 2 [Permanent Magnet (PM), Synchronous Reluctance (SynRM)]: 1
• When you set A1-02 = 8 and E9-01 = 1 or 2, also set b3-24 = 1. If b3-24 = 2, the
drive will detect oPE08 [Parameter Selection Error].
• When you set b3-24, it will trigger the drive to initialize b3-14 [Bi-directional
Speed Search]. After you set b3-24, set b3-14.

V/f CL-V/f OLV CLV AOLV
Sets the length of time the drive will wait to start the Speed Search Retry function.
V/f CL-V/f OLV CLV AOLV
Sets the level to find the motor rotation direction. Increase the value if the drive cannot
find the direction.
V/f CL-V/f OLV CLV AOLV
Sets the conditions necessary to start Speed Search.
0 : SS Only if RUN Applied Before BB
1 : SS Regardless of RUN/BB Sequence
V/f CL-V/f OLV CLV AOLV
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.
V/f CL-V/f OLV CLV AOLV
Sets the current level that decreases the output current during Current Detection Speed
Search.
V/f CL-V/f OLV CLV AOLV
Sets the current level that completes Speed Search.
V/f CL-V/f OLV CLV AOLV
Sets the function that starts Speed Search at start-up if the drive detects a Uv
[Undervoltage] when it receives a Run command.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the Low Back EMF Detection Level. Usually it is not necessary to change this
setting.
V/f CL-V/f OLV CLV AOLV
Sets the voltage level for Speed Search restart. Usually it is not necessary to change this
setting.
V/f CL-V/f OLV CLV AOLV
Sets the level to determine the regenerative state during speed search. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the length of time that the drive will run Speed Search.
V/f CL-V/f OLV CLV AOLV
Sets the length of time that the drive will increase the current from zero current to the
setting value of b3-06 [Speed Estimation Current Level 1].
