3) Each motor constant can be set individually. | ⇒ For details, see selection 3 in 6.13. |
5) Energy-saving
Setting V/F control mode selection to (automatic
Energy can be saved in all speed areas by detecting load current and flowing the optimum current that fits the load.
★Motor constant must be set
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.
There are two procedures for setting the motor constant.
1)The motor constant can be set automatically
⇒For details, see selection 2 in 6.13.
2) Each motor constant can be set individually.⇒ For details, see selection 3 in 6.13.
6) Precautions on vector control
1) | The sensorless vector control exerts its characteristics effectively in frequency areas below the base fre- |
| |
| quency ( ). The same characteristics will not be obtained in areas above the base frequency. | 5 | |
2) | Set the base frequency to anywhere from 40 to 120Hz during sensorless vector control ( ). | ||
3) | Use a general purpose |
| |
| ity or one rank below. |
|
|
| The minimum applicable motor capacity is 0.1kW. |
|
|
4) | Use a motor that has 2~8 P. |
|
|
5) | Always operate the motor in single operation (one inverter to one motor). Sensorless vector control can- |
| |
| not be used when one inverter is operated with more than one motor. |
|
|
6) | The maximum length of wires between the inverter and motor is 30 meters. If the wires are longer than |
| |
| 30 meters, set standard |
| |
| sorless vector control. |
|
|
| However the effects of voltage drop cause |
| |
| somewhat lower. |
|
|
7) | Connecting a reactor or surge voltage suppression filter between the inverter and the motor may reduce |
| |
| ) rendering sensorless vector |
| |
| control unusable. |
