 Adjusts the output voltage for the flux weakening curve.
 For the spindle application, use this adjustment method:
1. Run the motor to the highest frequency.
2. Observe the output voltage.
3. Adjust the Pr.11-21 (motor 1) or Pr.11-22 (motor 2) setting to make the output voltage reach
the motor rated voltage.
4. The larger the setting value, the greater the output voltage.
