Description
V/f CL-V/f OLV CLV AOLV
Sets the function to prevent hunting.
0 : Disabled
1 : Enabled
2 : Enabled (High Carrier)
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 how the drive decreases the motor vibration that is caused by leakage current.
Usually it is not necessary to change this setting.
1 : 2-Phases
2 : 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 [DCBus Stab.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.
1 : No Calibration
2 : Calib@Next Start
3 : Calib@Every 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 setting.
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness of the hunting prevention function. Usually it is not necessary to
change this setting.
Description
V/f CL-V/f OLV CLV AOLV
Sets the gain of the AFR function 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 that sets the speed difference of the AFR function. Use this
parameter for speed searches or regeneration. Usually it is not necessary to change this
setting.
