Description
V/f CL-V/f OLV CLV AOLV
This compensation gain improves the control characteristics for
motoring loads in the low speed range.
V/f CL-V/f OLV CLV AOLV
Set a frequency that enables the settings for n4-60 [Motoring Low
Speed Comp Gain], n4-62 [Low Speed compensation Gain]. When
the output frequency < n4-61, torque compensation is carried out in
accordance with the settings for n4-60, n4-62. Normally there is no
need to change this setting.
V/f CL-V/f OLV CLV AOLV
This compensation gain improves the control characteristics for
regenerative loads in the low speed range.
V/f CL-V/f OLV CLV AOLV
[SwitchingFreq forEstimation gain], this adjusts the responsiveness
of the speed estimation.
V/f CL-V/f OLV CLV AOLV
67 [SwitchingFreq forEstimation gain], this adjusts the
responsiveness of the speed estimation.
V/f CL-V/f OLV CLV AOLV
In high speed ranges, where the output frequency is ≥ n4-67
[SwitchingFreq forEstimation gain], this adjusts the responsiveness
of the magnetic flux estimation. Normally there is no need to change
this setting.
V/f CL-V/f OLV CLV AOLV
67 [SwitchingFreq forEstimation gain], this adjusts the
responsiveness of the magnetic flux estimation. Normally there is no
need to change this setting.
V/f CL-V/f OLV CLV AOLV
following: n4-63 [SpdEstimationResponseForHighFreq], n4-64
[SpdEstimationResponse forLowFreq], n4-65
[FluxEstimationResponseForHighFrq], and n4-66
[FluxEstimationResponseForLowFreq]. Normally there is no need
to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time constant for the speed estimation value.
Normally there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Stabilizes motor vibrations through unified control of magnetic flux.
V/f CL-V/f OLV CLV AOLV
Normally there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Select whether an encoder option is to be connected or not when set
to A1-02 = 4 [Control Method Selection = Advanced OpenLoop
Vector Control].

If the encoder is disconnected, this determines whether the drive is
to restart in the WithOut PG mode, or is to restart in the With PG
mode.
