YASKAWA TOEPYAIGA8002B GA800 Drive Programming
Description
V/f CL-V/f OLV CLV AOLV
Sets the direction of Speed Search to the direction of the frequency reference or in the
motor rotation direction as detected by the drive.
0 : Disabled
1 : Enabled
Note:
• Refer to page 125 for information about the initial value of b3-14 [Bi-directional
Speed Search] that applies when you set these parameters:
–A1-02 = 0, 2, 8 [Control Method Selection = V/f, OLV, EZOLV]
–E9-01 = 0 [Motor Type Selection = Induction (IM)]
–b3-24 = 1 [Speed Search Method Selection = Speed Estimation Speed Search]
• The initial value of b3-14 is 0 when you set these parameters:
–A1-02 = 0, 2, 8
–E9-01 = 0
–b3-24 = 2 [Current Detection 2]
• Refer to page 125 for information about the initial value of b3-14 that applies when
you set these parameters:
–A1-02 = 1, 4, 8 [CL-V/f, AOLV, EZOLV]
–E9-01 = 1, 2 [Permanent Magnet (PM), Synchronous Reluctance (SynRM)]
• When you change A1-02, b3-24, and E9-01, also set b3-14.
V/f CL-V/f OLV CLV AOLV
Sets the current level for the search retry function in Speed Estimation Speed Search as a
percentage where drive rated current is a setting value of 100%.
V/f CL-V/f OLV CLV AOLV
Sets the length of time that the drive will wait to retry Speed Estimation Speed Search
when too much current flow stopped the Speed Search.
V/f CL-V/f OLV CLV AOLV
Sets the number of times to restart Speed Search if Speed Search does not complete.
V/f CL-V/f OLV CLV AOLV
Sets the Speed Search method when you start the motor or when you return power after a
momentary power loss.
Note:
• The default setting is different for different control methods.
–A1-02 = 0, 2 [Control Method Selection = V/f, OLV]: 2
–A1-02 = 1 [CL-V/f]: 1
–A1-02 = 8 [EZOLV] and E9-01 = 0 [Motor Type Selection = Induction (IM)]: 2
–A1-02 = 8 and E9-01 ≠ 0: 1
• Set b3-24 = 1. If b3-24 = 2, the drive will detect oPE08 [Parameter Selection
Error].
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.
