  Default: 0000h 
  Settings  bit0: Auto-tuning for ASR and APR 
 
 
  bit1: Inertia estimate (only in FOCPG mode) 
    bit2: Zero servo 
    bit6: 0Hz linear-cross 
    bit7: Save or do not save the frequency 
    bit8: Maximum speed for point-to-point position control 
  bit0=0: Manual adjustment for ASR and APR gain, Pr.11-06–Pr.11-11 are valid and 
Pr.11-03–Pr.11-05 are invalid. 
bit0=1: Auto-tuning for ASR and APR gain, the system automatically generates an ASR setting, 
Pr.11-06–Pr.11-11 are invalid and Pr.11-03–Pr.11-05 are valid.
 
 
  When the drive needs to keep a certain torque at zero-speed, or it needs a steady frequency 
output at extreme low speed, increase Pr.11-05 zero-speed bandwidth appropriately. When the 
speed is in high-speed area, if the output current trembles seriously and makes the drive vibrate, 
then decrease the high-speed bandwidth. 
For example: 
Manual gain 
Response: 
[Pr.11-10, Pr.11-11] > [Pr.11-06, Pr.11-07] > [Pr.11-08, Pr.11-09] 
Auto gain  Pr.11-05 = 15 Hz, Pr.11-03 = 10 Hz, Pr.11-04 = 8 Hz
