Note 1: The same characteristic can be obtained by setting the V/F control mode selection parameter to
(automatic torque boost control) and the auto-tuning parameter to (auto-tuning).
Refer to section 6.14
Note 2: Setting to automatically programs to .
2) When using vector control (increasing starting torque and high-precision operations)
is set to (Vector control + auto-tuning)
Setting torque boost setting macro function control to (vector control + auto-tuning) provides high
starting torque bringing out the maximum in motor characteristics from the low-speed range. This suppresses
changes in motor speed caused by fluctuations in load to provide high precision operation. This is an optimum
feature for elevators and other load transporting machinery.
Note 1: The same characteristic can be obtained by setting the V/F control mode selection parameter
to (vector control) and the auto-tuning parameter to (auto-tuning).
Refer to section 6.14
Note 2: Setting to automatically programs to .
3) Energy-saving operation
is set to (Energy saving + auto-tuning)
When torque boost setting macro function control is set to (energy saving + auto-tuning), the inverter
always passes a current appropriate to the load for energy saving.
Note 1: The same characteristic can be obtained by setting the V/F control mode selection parameter
to (automatic energy saving) and the auto-tuning parameter to (auto-tuning).
Note 2: When is set to , is automatically set to .
[Example of parameter setting]
Operation panel
action
LED display Operation
.
Displays the output frequency. (Perform during operation stopped.)
(When standard monitor display selection = [Output frequency])
The first basic parameter “” (history function) is displayed.
Turn the setting dial to the right to change the parameter to
(torque boost setting macro function).
Parameter values can be read by pressing the center of the setting
dial.
Turn the setting dial to the right to change the parameter to
(energy saving + auto-tuning). (Right side is the setting value, left
side is the history of the previous setting.)
Press the center of the setting dial to save the changed parameter.
and the parameter are displayed alternately.
