V/f CL-V/f OLV CLV AOLV
Sets the responsiveness of the magnetic flux estimation in low speed ranges, where 0 ≤ the output
frequency, which is < n4-67 [Estimate Gain Switchover Freq]. Usually it is not necessary to change
this setting.
V/f CL-V/f OLV CLV AOLV
Sets the switching frequency for estimation gain for these parameters:
n4-63 [Speed EstimateResponse@High Freq]
n4-64 [Speed Estimate Response@Low Freq]
n4-65 [Flux Estimate Response@High Freq]
n4-66 [Flux Estimate Response @Low Freq]
Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time constant for the speed estimation value. Usually it is not necessary to
change this setting.
V/f CL-V/f OLV CLV AOLV
Unifies control of magnetic flux to make motor vibrations more stable.
V/f CL-V/f OLV CLV AOLV
Sets the function to make the drive more stable when operating at low speeds. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the flux estimation method. Usually it is not necessary to change this setting.
0 : Method 1
1 : Method 2
V/f CL-V/f OLV CLV AOLV
Sets the requirement for an encoder option when A1-02 = 4 [Control Method Selection = Advanced
Open Loop Vector].
0 : Without Encoder
1 : With Encoder
V/f CL-V/f OLV CLV AOLV
Sets the restart mode to Without Encoder Mode or the With Encoder Mode when an encoder is
disconnected.
0 : Without Encoder
1 : With Encoder
V/f CL-V/f OLV CLV AOLV
Sets the control level for flux loop control output.
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.
