Description
V/f CL-V/f OLV CLV AOLV
Sets the length of time until the automatically reduced carrier frequency returns to the
condition before the reduction.
V/f CL-V/f OLV CLV AOLV
Sets the function to cause an HCA [Current Alarm] when the output current is more
than 150% of the drive rated current.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the STPo [Desynchronization Error] detection level as a percentage of the output
current.
V/f CL-V/f OLV CLV AOLV
Sets the detection level for STPo [Desynchronization Error] related to the ACR integral
value.
V/f CL-V/f OLV CLV AOLV
Sets the length of time until the drive detects STPo after exceeding the value of L8-51
[STPo Current Level].
V/f CL-V/f OLV CLV AOLV
Sets the Id deviation detection function for STPo [Desynchronization Error].
0 : Disable
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the protection function for the internal braking transistor.
0 : Disable
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the length time that the acceleration stall prevention function can continue to
operate before the drive detects an STPo [Desynchronization Error].
V/f CL-V/f OLV CLV AOLV
Sets the number of times the acceleration stall prevention function can operate until
speeds match before the drive detects an STPo [Desynchronization Error].
V/f CL-V/f OLV CLV AOLV
Sets the detection level that the control fault must be equal to or more than to cause an
STPo [Desynchronization Error].
V/f CL-V/f OLV CLV AOLV
Sets the length of time the drive will wait to start baseblock after detecting LSo [LSo
Fault].
V/f CL-V/f OLV CLV AOLV
Sets the detection level for LSo [Low Speed Motor Step-Out] as a percentage of E1-04
[Max Output Frequency].
V/f CL-V/f OLV CLV AOLV
Sets the average count of LSo [Low Speed Motor Step-Out] detections.
Description
V/f CL-V/f OLV CLV AOLV
Sets the detection time for FAn1 [Drive Cooling Fan Failure]. The manufacturer
recommends that you do not change this parameter value.
