5.2.2 Selecting the Advanced magnetic flux vector control
• To use the Advanced magnetic flux vector control, set the motor capacity, the number of motor poles, and
the motor type using Pr.80 and Pr.81.
Advanced magnetic flux vector control
1. Perform secure wiring. (Refer to page 39.)
2. Make the motor setting. (Pr.71)
*1 For the other setting values of Pr.71, refer to page 351.
*2 For offline auto tuning, refer to page 353.
3. Set the motor overheat protection. (Pr.9) (Refer to page 230)
Set the rated motor current (A) in Pr.9 Electronic thermal O/L relay.
4. Setting the motor capacity and the number of motor poles. (Pr.80, Pr.81) (Refer to page 145.)
Set the motor capacity (kW) in Pr.80 Motor capacity, and set the number of motor poles in Pr.81 Number of motor
poles. (V/F control is performed when the setting is "9999" (initial value).)
5. Set the rated motor voltage and frequency. (Pr.83, Pr.84) (Refer to page 353.)
Set the rated motor voltage (V) in Pr.83 Rated motor voltage, and set the rated motor frequency (Hz) in Pr.84
Rated motor frequency.
6. Set the operation command. (Refer to page 204.)
Select the start command and speed command.
7. Test run
As required
• Perform offline auto tuning. (Pr.96) (Refer to page 353.)
• Select the online auto tuning. (Pr.95) (Refer to page 371.)
NOTE
• Under this control, rotations are more likely to be uneven than under V/F control. (This control method is not suitable for
grinder, wrapping machine, etc., which require even rotation at a low speed.)
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
