12.1-11-7

11-21
Flux Weakening Curve for Motor 1 Gain Value
Default: 90
Settings 0–200%

11-22
Flux Weakening Curve for Motor 2 Gain Value
Default: 90
Settings 0–200%
 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.

11-23
Flux Weakening Area Speed Response
Default: 65
Settings 0–150%
 Controls the speed in the flux weakening area. The larger the value set for Pr.11-23, the faster the
acceleration/deceleration. In general, you do not need to adjust this parameter.

11-24
APR Gain
Default: 10.00
Settings 0.00–40.00 Hz (IM) / 0.00–100.00 Hz (PM)
 Sets the Kip gain of the internal position (MIx = 35).
 The pulse-train position command (MIx = 37) controls Kp gain, and this can adjust the value of
Pr.11-05 directly. The larger the setting value of Pr.11-05, the smaller the static error.

11-25
Gain Value for the APR Feed Forward
Default: 30
Settings 0–100
 This parameter is valid to the internal position (MIx = 35) and position control pulse command
(MIx = 37). A larger value set can shorten the pulse-train tracking error, but it may easily to
cause overshoot.
