Default
11-21
Flux weakening curve for motor 1
gain value
0 to 200%
90
11-22
Flux weakening curve for motor 2
gain value
0 to 200%
90
Adjusts the output voltage for the flux weakening curve.
For the spindle application, use this adjustment method:
● Run the motor to the highest frequency.
● Observe the output voltage.
● Adjust the Pr.11-21 (motor 1) or Pr.11-22 (motor 2) setting to make the output voltage reach the motor rated
voltage.
The larger the setting value, the greater the output voltage.
