V/f CL-V/f OLV CLV AOLV
Suppresses current hunting and overshooting that occurs when the drive stalls during
acceleration. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the time constant to adjust the acceleration rate when L3-01 = 3 [Stall Prevention
during Accel = Current Limit Method]. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the function to enable and disable the best S-curve characteristic used for current-
limited acceleration.
0 : Disable
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the level to detect speed agree or motor speed.
Sets the level to detect speed agree or motor speed when H2-01 to H2-03 = 2, 3, 4, 5
[MFDO Function Selection = Speed Agree 1, User-set Speed Agree 1, Frequency
Detection 1, Frequency Detection 2].
V/f CL-V/f OLV CLV AOLV
Sets the width to detect speed agree or motor speed.
Sets the width to detect speed agree or motor speed when H2-01 to H2-03 = 2, 3, 4, 5
[MFDO Function Selection = Speed Agree 1, User-set Speed Agree 1, Frequency
Detection 1, Frequency Detection 2].
V/f CL-V/f OLV CLV AOLV
Sets the level to detect speed agree or motor speed.
Sets the speed agree detection level or motor speed detection level when H2-01 to H2-03 =
13, 14, 15, 16 [MFDO Function Selection = Speed Agree 2, User-set Speed Agree 2,
Frequency Detection 3, Frequency Detection 4].
V/f CL-V/f OLV CLV AOLV
Sets the width to detect speed agree or motor speed.
Sets the width to detect speed agree or motor speed when H2-01 to H2-03 = 13, 14, 15, 16
[MFDO Function Selection = Speed Agree 2, User-set Speed Agree 2, Frequency
Detection 3, Frequency Detection 4].
V/f CL-V/f OLV CLV AOLV
Sets the operation when the drive detects a loss of frequency reference.
0 : Stop
1 : Run at (L4-06 x Last Reference)
V/f CL-V/f OLV CLV AOLV
Sets the frequency reference as a percentage to continue drive operation after it detects a
frequency reference loss. The value is a percentage of the frequency reference before the
drive detected the loss.
V/f CL-V/f OLV CLV AOLV
Sets the condition that activates speed detection.
0 : No Detection during Baseblock
1 : Detection Always Enabled
V/f CL-V/f OLV CLV AOLV
Sets the number of times that the drive will try to restart.
V/f CL-V/f OLV CLV AOLV
Sets the function that sends signals to the MFDO terminal set for Fault [H2-xx = E] while
the drive is automatically restarting.
0 : Active Only when Not Restarting
1 : Always Active
