V/f CL-V/f OLV CLV AOLV
Sets the feed forward function.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the length of time for the motor to accelerate from the stopped to the maximum
frequency with a single motor at the rated torque. Inertia Tuning automatically sets the
motor acceleration time.
V/f CL-V/f OLV CLV AOLV
Sets the ratio between load inertia and motor inertia. Inertia Tuning automatically sets the
Feedforward Control Gain value.
V/f CL-V/f OLV CLV AOLV
Sets the response frequency for the speed reference. Usually it is not necessary to change
this parameter.
V/f CL-V/f OLV CLV AOLV
Sets the type of motor data that Online Tuning uses for OLV control.
0 : Disabled
1 : Line-to-Line Resistance Tuning
2 : Voltage Correction Tuning
V/f CL-V/f OLV CLV AOLV
Sets the compensation gain when n6-01 = 2 [Online Tuning Selection = Voltage
Correction Tuning]. Usually it is not necessary to change this parameter.
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness for online resistor tuning. Set this parameter to approximately
1.000 to enable the function. The function is disabled when the value is 0.000.
V/f CL-V/f OLV CLV AOLV
Sets the oscillation suppression gain for the low speed range.
V/f CL-V/f OLV CLV AOLV
Sets the response gain related to changes in the load.
V/f CL-V/f OLV CLV AOLV
Sets the speed calculation gain during usual operation. Usually it is not necessary to
change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the speed calculation gain during a speed search.
V/f CL-V/f OLV CLV AOLV
Sets the speed range to operate with the pull-in current command. Drive rated frequency =
100% value. If there is a large quantity of oscillation when you operate in the low speed
range, increase the setting value.
