motor. Only ABZ incremental encoder and resolver are applicable to asynchronous motor.
After installation of the PG card is complete, set this parameter properly based on the actual condition. Otherwise,
the frequency inverter cannot run properly.
d0-23
Encoder type selection Default 0
Setting
Range
0 Forward
1 Reverse
d0-24
Encoder installation angle
Default
0.0°
Setting Range
0.0°~359.9°
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".
d0-25
Encoder type selection Default 0
Setting
Range
0 Forward
1 Reverse
d0-26
Encoder installation angle Default 0.0°
Setting Range
0.0°~359.9°
These two parameters are valid only when the UVW encoder is applied to a synchronous motor. They can be
obtained by synchronous motor no-load auto-tuning or with-load auto-tuning. After installation of the
synchronous motor is complete, the values of these two parameters must be obtained by motor auto-tuning.
Otherwise, the motor cannot run properly.
d0-27
Number of pole pairs of resolver Default 1
Setting Range
1~99
If a resolver is applied, set the number of pole pairs properly.
d0-28
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 1 auto-tuning selection Default 0
Setting
Range
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: No auto-tuning
Auto-tuning is prohibited.
1: Asynchronous motor static auto-tuning
