+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 H | ||
to H properly. |
| |
Be sure to set H (rated current of motor) and H (rated speed of motor) correctly, as specified on | ||
the motor’s nameplate. For the setting of H | ||
There are two procedures for setting the other motor constants. | ||
1) | The motor constant can be automatically set | |
| Set the extended parameter H to . | ⇒ For details, see selection 1 in 6.15.1. |
2) | Each motor constant can be set individually. | ⇒ For details, see selection 2 in 6.15.1. |
5) |

6) Operating a permanent magnet motor
Setting of V/F control mode selection RV to (PM motor control)
Permanent magnet motors (PM motors) that are light, small in size and highly efficient, as compared to induction motors, can be operated in
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 H to H properly. Be sure to set H (rated current of motor) and H (rated speed of motor) correctly, as specified on the motor’s nameplate. For the setting of H
2)The sensorless vector control exerts its characteristics effectively in frequency areas below the base frequency (XN). 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 (RV=).
4)Use a general purpose
The minimum applicable motor capacity is 0.1kW.
