Description
V/f CL-V/f OLV CLV AOLV
Sets the function to enable and disable ground fault protection.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets operation of the heatsink cooling fan.
1 : Dur Run (OffDly)
2 : Always On
3 : Fan ON @Heating of Drive
V/f CL-V/f OLV CLV AOLV
Sets the length of time that the drive will wait before stopping the cooling fan after
cancelling the Run command when L8-10 = 1 [Fan Operate Selection = Dur Run
(OffDly)].
V/f CL-V/f OLV CLV AOLV
Sets the ambient temperature of the drive installation area.
V/f CL-V/f OLV CLV AOLV
Sets the function to decrease drive overload at low speeds to prevent damage to the
main circuit transistor during low speed operation (at 6 Hz or slower) to prevent oL2
[Drive Overloaded].
Note:
Contact the manufacturer before disabling this function at low speeds. If you
frequently operate drives with high output current in low speed ranges, it can cause
heat stress and decrease the life span of drive IGBTs.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Set the software current limit selection function to prevent damage to the main circuit
transistor caused by too much current.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the ratio at which the drive derates the frequency reference when during an oH
alarm.
V/f CL-V/f OLV CLV AOLV
Sets operation after the drive detects a CF fault when A1-02 = 4 [Control Method =
Adv OLVector].
1 : Disabled
2 : CF/STPo Detection Enabled
3 : CF ALM/Stop
V/f CL-V/f OLV CLV AOLV
Sets the PM motor overcurrent detection level as a percentage of the motor rated current
value.
V/f CL-V/f OLV CLV AOLV
Sets the function to detect LF2.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the LF2 [Output Current Imbalance] detection time.
V/f CL-V/f OLV CLV AOLV
Sets operation when the drive detects FAn [Internal Agitating Fan Fault].
0 : Ramp->Stop
1 : Coast->Stop
2 : Fast Stop (C1-09)
3 : Alarm Only
4 : Run@L8-19 Rate
V/f CL-V/f OLV CLV AOLV
Sets the type of drive installation.
0 : IP00/IP20/Open-Chassis
1 : Side-by-Side Mounting
2 : IP21/NEMA Type 1/IP55
3 : Finless/Ext.Heatsink
V/f CL-V/f OLV CLV AOLV
Sets the carrier frequency reduction function. The drive reduces the carrier frequency
when the output current is more than a specified level.
0 : Disabled
1 : Enable<6 Hz
2 : Enab@AllSpeed
