System Control
Settings
 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
Auto gain
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
Response:
[Pr.11-10, Pr.11-11] > [Pr.11-06, Pr.11-07] > [Pr.11-08, Pr.11-09]
Pr.11-05 = 15 Hz, Pr.11-03 = 10 Hz, Pr.11-04 = 8 Hz
