Description
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
Description
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
V/f CL-V/f OLV CLV AOLV
Sets the time for which the drive will try to restart. If the drive cannot restart inthe time
set in L5-03, the drive detects a fault. This is available when L5-05 = 0 [Auto-Restart
Method = Continuous/Immediate Attempts].
V/f CL-V/f OLV CLV AOLV
Sets the time interval between each Auto Restart attempt. This function is enabled when
L5-05 = 1 [Auto Restart Operation Selection = Use L5-04 Time].
V/f CL-V/f OLV CLV AOLV
Sets the count method for the Auto Restart operation.
0 : Continuous/Immediate Attempts
1 : Interval/Attempt after L5-04 sec
