Motor Parameter Identification
For the better control performance, motor parameters must be identified.
Identification Method
Application
Identification Effect
F01.34=01
Static self-learning of
asynchronous motor
It is applied where the motor and load
cannot be separated easily and rotary
self-learning is not allowed.
General
F01.34=11
Static self-learning of
synchronous motor
F01.34=02
Rotary self-learning of
asynchronous motor
It is applied when the motor and load can
be separated easily. Before operation, the
motor shaft should be separated from the
load. The motor under load must not be
put into rotary self-learning.
Optimal
F01.34=12
Rotary self-learning of
synchronous motor
Prior to self-identification, make sure that the motor is stopped; otherwise,
self-identification cannot be performed properly.
5.7.1
Parameter identification steps
Where the motor and load can be separated, the mechanical load and motor should
be completely separated in the power-off status.
After the power-on, set the command source of the inverter to keyboard control
(F00.02=0).
Enter the nameplate parameters of the motor accurately.

For the asynchronous motor:
Set F01.34=1 for confirmation and press the RUN key. The inverter will start the static
self-identification of the motor.
Or, set F01.34=2 and press the RUN key. The inverter will start the rotary
self-identification of the motor.
For the synchronous motor:
Set F01.34=11 and press the RUN key. The inverter will start the static self-identification
of the motor.
