V/f CL-V/f OLV CLV AOLV
Sets the function to prevent hunting.
0 : Disabled
1 : Enabled (Normal)
2 : Enabled (High Carrier Frequency)
V/f CL-V/f OLV CLV AOLV
Sets the performance of the hunting prevention function. Usually it is not necessary to
change this parameter.
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 parameter.
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 parameter.
V/f CL-V/f OLV CLV AOLV
Sets how the drive decreases the motor vibration that is caused by leakage current. Usually
it is not necessary to change this parameter.
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
Adjusts the responsiveness of the oscillation suppression function for 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
V/f CL-V/f OLV CLV AOLV
Sets the gain for the hunting prevention function. This parameter functions best with a high
carrier frequency. Usually it is not necessary to change this parameter.
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness of the hunting prevention function. Usually it is not necessary to
change this parameter.
V/f CL-V/f OLV CLV AOLV
Sets the calibration time at start. Usually it is not necessary to change this parameter.
