Pm Motor Control; V/F 5-Point Setting - Toshiba TOSVERT VF-AS3 Instruction Manual

• <F405: Motor rated capacity>
• <F415: Motor rated current>
• <F417: Motor rated speed>
Two parameter setting methods are provided.
1) Setting with <F400: Offline auto-tuning>
Set <F400: Offline auto-tuning> to "5".
For details, refer to [6. 23. 1].
* If an auto-tuning error occurs, set motor parameters individually by referring to [6. 23. 1]
"■Setting method 4: Manually setting motor parameter".
2) Manual setting
Set each motor constant.
For details, refer to [6. 23. 1].

6: PM motor control

4
Permanent magnet motors (PM motors) that are highly efficient can be operated in sensor-less
operation.
Setting of parameters for PM motor is required. For details, refer to [6. 23. 2].

7: V/f 5-point setting

V/f control characteristics can be created according to machinery. Set frequency and voltage in five
points and run the inverter with V/f control characteristics derived by connecting these points.
Set five points from VF1 to VF5 with the following parameters <F190> to <F199>.
