Chapter 12 Description of Parameter SettingsC2000-HS 
 
 
12.1-11-8 
 
 
Flux Weakening Curve for Motor 2 Gain Value 
 
 
  Default: 90 
  Settings  0–200% 
  Adjusts the output voltage for the flux-weakening curve (Pr.11-21, Pr.11-22). 
  For the spindle application, use this adjustment method: 
1.  Use it to adjust the output voltage when exceeding rated frequency. 
2.  Monitor 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. 
 
 
 
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.
 
 
 
APR Gain 
 
 
  Default: 10.0 
  Settings  0.0–40.0 Hz (IM) / 0.0–100.0 Hz (PM) 
  Sets the Kp gain of the internal position (MIx=35). 
 
 
Gain Value for the APR Feed Forward 
 
 
  Default: 30 
  Settings  0–100 
  This applies only to the internal position (MIx = 35) and position control pulse command (MIx = 
37).  A  larger  value  can  shorten  the  pulse  differential  and  speed  up  the  position  response; 
however, it may cause overshoot. 
 
 
APR Curve Time 
 
 
  Default: 3.00 
  Settings  0.00–655.35 sec. 
  This is valid when the multi-function input terminal is set to 35 (ON). The larger the setting value, 
the longer the position time.
