are unknown and it is not allowed to perform motor parameter autotuning, please input the
parameters manually by referring to parameters of kindred motors.
If motor power rating P30.01 is changed, P30.02~P30.14 will be automatically restored to
default setting of the standard motor.
P30.22 Autotuning of motor 1
Be sure to correctly enter motor 1 parameters P30.01~P30.06 before autotuning.
0: No action
1: Static autotuning of async motor
Static identification applies to the cases where rotary autotuning are not allowed. Set
P30.22 to 1, press the key RUN to start static autotuning. P30.22 will be restored to 0 upon
the completion of autotuning. In this way, P30.07~P30.09 are obtained after the completion
of autotuning.
2: Rotary autotuning of async motor
To perform rotatry autotuning, it is essential to disengage the motor from its load. Set P30.22
to 2, then press RUN to perform static autotuning, upon the completion of which, the motor
would accelerate to a fixed frequency in the set ramp-up time, maintaining a period of time,
and then stop by ramp down according to the set ramp down time. In this way, the autotuning
comes to an end, and P30.22 will be restored to 0. Parameters P30.07~P30.14 have be
obtained after the completion of rotary autotuning. To perform rotary autotuning, please set
appropriate ramp-up and ramp-down time (i.e. Accel/Decel time. If overcurrent or
overvoltage fault occurs during autotuning, please prolong Accel/Decel time accordingly.
 ATTENTION:

Please make sure the motor is in a stationary status before autotuning, or autotuning
cannot be performed normally.

Keypad displays "TUNE", and RUN indicator is lighting during autotuning.
indicator turns off upon the completion of autotuning.

If autotuning failed, the fault code "tUN" shall be displayed.
Overload protection mode of
P30.23
Determine the overload protection mode of motor 1.
0: No protection
Once 0 is selected, it would be impossible to perform motor overload protection. Please take
care.
1: Judged from motor current
Provide overload protection judged from output current and its lasting time. Overload
protection detection time is set by P30.24.
2: Judged from temperature transducer
Input motor temperature sensor signal through analog input channel set by P30.25. The
motor 1
Range: 0~3
Range: 0~2
