Description
V/f CL-V/f OLV CLV AOLV
Selects the operation of the carrier frequency reduction function.
The carrier frequency is reduced when the output current exceeds a
specific level.
0 : Disabled
1 : Enabled below 6 Hz
2 : Enabled for the EntireSpeedRange
V/f CL-V/f OLV CLV AOLV
Sets the time (off delay time) taken for the automatically reduced
carrier frequency to return to the state before the reduction.
V/f CL-V/f OLV CLV AOLV
Triggers an HCA [Current Alarm] when the output current exceeds
150% of the drive rated current.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the STPo [Desynchronization Error] on the basis of the output
current.
V/f CL-V/f OLV CLV AOLV
Sets the detection level for STPo [Desynchronization Error] on the
basis of the ACR integral value.
V/f CL-V/f OLV CLV AOLV
Sets the time until STPo is detected after the value of L8-51 [STPo I
Detection Level] is exceeded.
V/f CL-V/f OLV CLV AOLV
Enables or disables the Id deviation detection function for STPo
[Desynchronization Error].
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Enables or disables protection for the internal braking transistor.
0 : Disable
1 : Protection enabled
V/f CL-V/f OLV CLV AOLV
Sets the time that the acceleration stall prevention function can
continue to operate, after which the STPo [Desynchronization
Error] is detected.
V/f CL-V/f OLV CLV AOLV
Sets the number of times the acceleration stall prevention function
can operate until speeds match, after which the STPo
"Desynchronization Error" is detected.
V/f CL-V/f OLV CLV AOLV
STPo [Desynchronization Error] is detected when the control fault
reaches the detection level of L8-90.
V/f CL-V/f OLV CLV AOLV
detected.
V/f CL-V/f OLV CLV AOLV
Sets the detection level for LSo [LSo Fault] as a percentage of E1-
04 [Maximum Output Frequency].
V/f CL-V/f OLV CLV AOLV
Sets the average count of LSo [LSo Fault] detections.
