YASKAWA ELECTRIC SIEP C710617 01B YASKAWA AC Drive GA700 Technical Manual
Description
V/f CL-V/f OLV CLV AOLV
Sets the amount of deceleration when the torque reference is at
100% as a percentage of Maximum Output Frequency.
V/f CL-V/f OLV CLV AOLV
Adjusts the responsiveness of Droop control. Lower this setting
when drive response is slow. Raise this setting when hunting or
oscillation occur.
V/f CL-V/f OLV CLV AOLV
Enables or disables the limit when using Droop control.
0 : Disabled
1 : Enabled

V/f CL-V/f OLV CLV AOLV
Configures the gain for energy-saving control.
V/f CL-V/f OLV CLV AOLV
Configures the responsiveness for energy-saving control.
V/f CL-V/f OLV CLV AOLV
Configures the energy-saving coefficient. The energy-saving
coefficient is used to maintain maximum motor efficiency. The
default setting is the Yaskawa motor value.
V/f CL-V/f OLV CLV AOLV
Configures the time constant used by the drive to measure output
power.
V/f CL-V/f OLV CLV AOLV
On the basis that the motor rated voltage is the 100% value, this
parameter configures the limit value of the voltage range defined for
Search Operations as a percentage.
V/f CL-V/f OLV CLV AOLV
This coefficient maintains torque linearity. Enter the Ki value
written on the motor nameplate. Normally there is no need to
change this setting.
V/f CL-V/f OLV CLV AOLV
This coefficient maintains torque linearity. Enter the Kt value
written on the motor nameplate. Normally there is no need to
change this setting.
V/f CL-V/f OLV CLV AOLV
V/f CL-V/f OLV CLV AOLV
Configures the energy-saving control search operation frequency.
Normally there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Configures the amplitude of energy-saving control search
operations.
