The motor’s parameters auto-learning have dynamic auto-learning and static
auto-learning, the procedure is as follows:
1. Parameter dynamic auto-learning
The parameter dynamic auto-learning can be finished during the motor running, the
Acc-time(F0.10) and Dec-time (F0.11) must be reasonably set according to the motor’s
power, otherwise, if the Acc and Dec time is too short, it would cause over-current in the
process of dynamic auto-learning.
First, set the F3.08=1, the panel will display –TUN-, then press the RUN key, the
inverter begins to parameter dynamic auto-learn. During the process, the panel will
display TUN-0, TUN-1 in turn, when the panel displays -END-, the learning process is
over and success. If the drive displays the fault code E020 after the auto-learning, it
indicates that mistakes occur to the dynamic parameter auto-learning, the learning
process is failure, please confirm the input motor parameters and redo the steps.
☞Note: During the parameter dynamic auto-learning process, the motor and the load
should completely disconnect and proceed when the motor stops steadily, otherwise, the
obtained motor parameters maybe incorrect. The dynamic auto-learning is advised as far
as possible. In case that the motor and the load can not be completely disconnected by the
limitation of the scene, the static auto-learning can be used.
2. Parameter Static auto-learning
The static auto-learning can be done when the motor is still. First, set the F3.08=2, the
panel will display –TUN-, then press RUN key, now the drive begins to statically
auto-learn. During the process, the panel will display TUN-0, when the panel displays
-END-, the learning process is over and success. If the drive displays the fault code E020,
it indicates that mistakes occur to the static parameter auto-learning, the learning process
is failure, please confirm the motor’s parameters and redo the steps.
