11 Advanced Parameters

In this parameter group, ASR is the abbreviation for Adjust Speed Regulator.
System Control
11-00
Settings
 bit0 = 0: Manual adjustment for ASR gain, Pr.11-06–Pr.11-11 are valid and Pr.11-03–Pr.11-05
are invalid.
bit0 = 1: Auto-adjustment for ASR 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 extremely 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
bit1: Inertia estimate (only in FOCPG mode)
bit2: Zero speed servo
bit6: 0 Hz linear-cross (applied to 230V / 460V models)
bit7: Save or do not save the frequency
bit8: Maximum speed for point-to-point position control
bit11: Switch between IMFOCPG and IMVF modes
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
