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 properly.
Be sure to set (rated current of motor) and
the motor's nameplate. For the setting of
There are two procedures for setting the other motor constants.
1) The motor constant can be automatically set (auto-tuning).
Set the extended parameter
2) Each motor constant can be set individually.
5) Energy-saving
Setting of V/F control mode selection
Energy can be saved in all speed areas by detecting load current and flowing the optimum current that fits
the load.

2) Each motor constant can be set individually.
6) Operating a permanent magnet motor
Setting of V/F control mode selection
Permanent magnet motors (PM motors) that are light, small in size and highly efficient, as compared to
induction motors, can be operated in sensor-less operation mode.
Note that this feature can be used only for specific motors. For more information, contact your Toshiba dealer.
7) Precautions on vector control
1) When exercising vector control, be sure to set the extended parameters
sure to set (rated current of motor) and
the motor's nameplate. For the setting of
2) The sensorless vector control exerts its characteristics effectively in frequency areas below the base
frequency ( ). The same characteristics will not be obtained in areas above the base frequency.
3) Set the base frequency to anywhere from 40 to 120Hz during vector control (
4) Use a general purpose squirrel-cage motor with a capacity that is the same as the inverter's rated capacity or
one rank below.
The minimum applicable motor capacity is 0.1kW.
