0: Display the frequency reference (U1-01) after PID compensation has been
added.
1: Display the frequency reference (U1-01) before PID compensation has been
added.
Parameters b6-01 and b6-02 set the frequency to hold and the time to maintain
that frequency at start.
Parameters b6-03 and b6-04 set the frequency to hold and the time to maintain
that frequency at stop.
Sets the speed reduction gain applied at a torque reference of 100%. Set as a
percentage of motor base speed.
Used to adjust the responsiveness of Droop Control.
0: Disabled
1: Enabled
Sets the gain used for Energy Saving.
Sets a time constant for Energy Saving.
Determines the level of maximum motor efficiency. Setting range is 0.0 to
2000.0 maximum output up to 3.7 kW. The display resolution depends on the
rated output power of the drive after the Drive Duty has been set in parameter
C6-01. Refer to Model Number and Nameplate Check on page
Sets the limit for the voltage search operation as a percentage of the motor rated
voltage.
