Motor constant must be set
If the motor you are using is a 4P Toshiba standard motor and if it has the same capacity as the inverter,
there is basically no need to set the motor constant. In any other case, be sure to set the parameters
to
Be sure to set
the motor's nameplate. For the setting of
There are three procedures for setting the other motor constants.
1) The sensorless vector control and motor constants (auto-tuning) can be set at a time.
Set the basic parameter
2) The motor constant can be automatically set (auto-tuning).
Set the extended parameter
3) Each motor constant can be set individually.
5) Energy-saving
Energy can be saved in all speed areas by detecting load current and flowing the optimum current that fits

the load.

There are three procedures for setting the other motor constants.
1) Automatic energy-saving operation and a motor constant can be set at once. Set the basic parameter
2) The motor constant can be automatically set (auto-tuning). Set the extended parameter
3) Each motor constant can be set individually.
6) Achieving further energy savings
More substantial energy savings than those provided by setting
range by keeping track of the load current and passing a current appropriate to the load. The inverter cannot
respond to rapid load fluctuations, so that this feature should be used only for loads, such as fans and
pumps, that are free of violent load fluctuations.
