Description
V/f CL-V/f OLV CLV AOLV
Triggers an HCA [High 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
Enables or disables protection for the internal braking transistor.
0 : Disable
1 : Protection Enabled
Description
V/f CL-V/f OLV CLV AOLV
Sets the detection time for FAn1 [Drive Cooling Fan Failure]. Yaskawa
recommends that you do not change this parameter value.
Description
V/f CL-V/f OLV CLV AOLV
Enables or disables the hunting prevention function.
0 : Disabled
1 : Enabled
2 : Enabled (High Carrier Frequency)
V/f CL-V/f OLV CLV AOLV
Adjusts the behavior of the hunting prevention function. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time constant of the hunting prevention function.
Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the performance of the hunting prevention function. This parameter
adjusts Reverse run. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the method of suppressing motor vibration caused by leakage current.
Usually it is not necessary to change this setting.
0 : 2-Phases
1 : 3-Phases
V/f CL-V/f OLV CLV AOLV
Sets the oscillation suppression function for the DC bus voltage.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets a length of time for the drive to suppress oscillation in relation to the
DC bus voltage. Set n1-13 = 1 [DC Bus Stabilization Control = Enabled] to
enable this parameter.
V/f CL-V/f OLV CLV AOLV
Sets the calibration method that the drive uses to decrease torque/current
ripple.
0 : No Calibration
1 : One Time Calibrate at Next Start
2 : Calibrate Every Time at Start
