Description
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
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 setting.
Description
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 setting.
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.
Description
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.
