Description
V/f CL-V/f OLV CLV AOLV
Sets the function to prevent hunting.
0 : Disable
1 : Enabled
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.
Description
V/f CL-V/f OLV CLV AOLV
Sets the gain of the AFR function for forward run as a magnification value. Usually it is
not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the time constant that sets the rate of change for the AFR function. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the time constant to determine the variation in speed of the AFR function. Use this
parameter during regeneration. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain of the AFR function for reverse run as a magnification value. Usually it is
not necessary to change this setting.
