Each time "Rated motor power" (d0-00) or "Rated motor voltage" (d0-01) is changed; the frequency inverter will
automatically modify the values of d0-15~ d0-19.
You can also directly set the parameters based on the data provided by the synchronous motor manufacturer.

parameter d0-23 is valid only for ABZ incremental encoder (d0-20 = 0) and is used to set the A/B phase sequence
of the ABZ incremental encoder.
It is valid for both asynchronous motor and synchronous motor. The A/B phase sequence can be obtained through
"Asynchronous motor complete auto-tuning" or "Synchronous motor no-load auto-tuning".
d0-29
Encoder fault detection time
Default
0.0s
Setting Range
0.0s: No action
0.1s~10.0s
This parameter is used to set the detecting time that a wire-break faults. If it is set to 0.0s, the frequency inverter
does not detect the encoder wire-break fault. If the duration time of the encoder wire-break fault detected by the
frequency inverter exceeds the time set in this parameter, the frequency inverter reports Err20.
d0-30
Motor auto-tuning selection
Default
0
Setting
Range
0
No auto-tuning
1
Asynchronous motor static auto-tuning
2
Asynchronous motor dynamic complete auto-tuning
3
Asynchronous motor static complete auto-tuning
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 d0-00 ~
d0-04 firstly. The frequency inverter will obtain parameters of d0-05 ~ d0-07 by static auto-tuning.
Action guide: Set this parameter to 1, and press
RUN
key. Then, the frequency inverter starts static auto-tuning.
2: Asynchronous motor dynamic 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 frequency inverter performs static auto-tuning first and then accelerates to 80% of the
rated motor frequency within the acceleration time set in b0-21. The frequency inverter keeps running for a certain
period and then decelerates to stop with deceleration time set in b0-22.
Before performing complete auto-tuning, properly set the motor type, motor nameplate parameters of b0-00 and
d0-00~ d0-04, "Encoder type" (d0-20) and "Encoder pulses per revolution" (d0-19) first.
