Function Code Parameter Name Setting Range Default
F1-34 Number of pole pairs of resolver 1–65535 1
If a resolver is applied, set the number of pole pairs properly.
Function Code Parameter Name Setting Range Default
F1-36
Encoder wire-break fault detection
time
0.0s: No action
0.1–10.0s
0.0s
This parameter is used to set the time that a wire-break fault lasts. If it is set to 0.0s, the AC
drive does not detect the encoder wire-break fault. If the duration of the encoder wire-break
fault detected by the AC drive exceeds the time set in this parameter, the AC drive reports
Err20.
Function Code Parameter Name Setting Range Default
F1-37
Auto-tuning
selection
0: No auto-tuning
1: Asynchronous motor static auto-tuning
2: Asynchronous motor complete auto-tuning
11: Synchronous motor with-load auto-tuning
12: Synchronous motor no-load auto-tuning
0
• 0: No auto-tuning
Auto-tuning is prohibited.
• 1: Asynchronous motor static auto-tuning
It is applicable to scenarios where complete auto-tuning cannot be performed because
the asynchronous motor cannot be disconnected from the load.
Before performing static auto-tuning, properly set the motor type and motor nameplate
parameters of F1-00 to F1-05 rst. The AC drive will obtain parameters of F1-06 to F1-
08 by static auto-tuning.
Set this parameter to 1, and press
. Then, the AC drive starts static auto-tuning.
• 2: Asynchronous motor complete auto-tuning
To perform this type of auto-tuning, ensure that the motor is disconnected from the load.
During the process of complete auto-tuning, the AC drive performs static auto-tuning
rst and then accelerates to 80% of the rated motor frequency within the acceleration
time set in F0-17. The AC drive keeps running for a certain period and then decelerates
to stop within deceleration time set in F0-18.
Before performing complete auto-tuning, properly set the motor type, motor nameplate
parameters of F1-00 to F1-05, "Encoder type" (F1-28) and "Encoder pulses per
revolution" (F1-27) rst.
The AC drive will obtain motor parameters of F1-06 to F1-10, "A/B phase sequence of
ABZ incremental encoder" (F1-30) and vector control current loop PI parameters of F2-
13 to F2-16 by complete auto-tuning.
