YASKAWA TOEPYAIGA8001B GA800 Drive Maintenance & Troubleshooting
V/f CL-V/f OLV CLV AOLV
Sets the amount of deceleration when the torque reference is at 100% as a percentage of E1-04
[Maximum Output Frequency].
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness of Droop control. Decrease this setting when drive response is slow. Increase
this setting when hunting or oscillation occur.
V/f CL-V/f OLV CLV AOLV
Sets the Droop control limit function.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the Energy-saving control function.
0 : Disabled
1 : Enabled
2 : Automatic Optimization
Note:
Setting 2 is available only when A1-02 = 6, 7 [Control Method Selection = AOLV/PM, CLV/PM]
and in Expert Mode.
V/f CL-V/f OLV CLV AOLV
Sets the gain for Energy-saving control.
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness for Energy-saving control.
V/f CL-V/f OLV CLV AOLV
Sets the Energy-saving control coefficient to maintain maximum motor efficiency. The default setting
is for Yaskawa motors.
V/f CL-V/f OLV CLV AOLV
Sets the time constant to measure output power.
V/f CL-V/f OLV CLV AOLV
Sets the voltage limit for Search Operation as a percentage of the motor rated voltage.
V/f CL-V/f OLV CLV AOLV
Sets torque linearity. This parameter uses the Ki value from the motor nameplate. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets torque linearity. This parameter uses the Kt value from the motor nameplate. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the d-axis current reference filter time constant.
V/f CL-V/f OLV CLV AOLV
Sets the frequency of Energy-saving control search operations. Usually it is not necessary to change
this setting.
V/f CL-V/f OLV CLV AOLV
Sets the amplitude of Energy-saving control search operations.
