d0.16~d0.19 are synchronous motors’ parameters,d0.20 is the installation angle, they are got
through inverter auto-tuning.

Default: 0
0: No auto-tuning
Auto-tuning is prohibited.
1: Motor static auto-tuning
It is applicable to scenarios where complete auto-tuning cannot be performed because the motor
cannot be disconnected from the load. Before performing static auto-tuning, properly set the motor
type and motor nameplate parameters of d0.00 to d0.07 first. The AC drive will obtain parameters of
d0.08 to d0.10 by static auto-tuning. Set this parameter to 1, and press RUN. Then, the AC drive starts
static auto-tuning.
2: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 first and then
accelerates to 80% of the rated motor frequency within the acceleration time 4. The AC drive keeps
running for a certain period and then decelerates to stop within deceleration time 4
Before performing complete auto-tuning, properly set the motor type, motor nameplate
parameters of d0.00 to d0.07.
The AC drive will obtain motor parameters of d0.08 to d0.12 by complete auto-tuning.
Set this parameter to 2, and press RUN. Then, the AC drive starts complete auto-tuning.
ATTENTION:
1) Please make sure the motor is in a stationary status before autotuning, or autotuning cannot be
performed normally.
2) Keypad displays "TUNE", and RUN indicator is lighting during autotuning. RUN indicator turns
off upon the completion of autotuning.
3) If autotuning failed, the fault code “Err17" shall be displayed.
Group d1 V/f Control Parameters of Motor 1
d1.00
V/f curve setting
Range:0
～
13
Default: 0
Set the relation between output voltage and output frequency of the drive when motor 1 is under
V/f control.
0: Linear V/f
Applies to general constant-torque load. When drive output frequency is 0, output voltage will be 0,
while when output frequency is rated frequency of motor, the output voltage would be rated voltage of
motor.
1: Broken line V/f (determined by d1.03
～
d1.10)
Applies to spin drier, centrifuge, industrial washing machine and to other special loads. When
drive output frequency is 0, output voltage will be 0, while when output frequency is rated frequency of
motor, the output voltage would be rated voltage of motor. What is different is this pattern can set 4
