After the motor self-learning is normally ended, F1.06-F1.10 setting values are automatically replaced.
These parameters are the basis of high performance vector control and have direct effect on the control
performance.
Important: users DO NOT change this group parameters at will.

1: self-learning of parameters
Prior to parameters self-learning, the motor must be disconnected with its load-ensuring the motor at
no-load condition, and confirming the motor is at static state.
Prior to parameters self-learning, it is a must to correctly input the motor nameplate para meters
(F1.01~F1.05), otherwise what is se lf learned about motor parameters may be not correct.
Prior to parameters self-learning, the Acceleration and Deceleration ti me (F0.08 and F0.09) should be
set properly based on the motor inertia, otherwise over current fault may happen during motor parameters
self-learning.
When the self-learning of motor parameters is started by setting F1.11 as 1 and then pushing the button

Please note, the start and stop of the parameters self-learning can only be done through keypad. Once
the parameter self-learning is finishe d, this function code automatically r estores to 0.

point frequency
Above parameters are valid only to vector control, but invalid to V/F control. When the frequency is
less than the switching frequency point 1 (F1.14), the speed loop PI parameters are F1.12 and F1.13. When
frequency is higher than the switching frequency point 2 (F1.17),the speed loop PI parameters are F1.15
and F1.16. Between the switching points, PI parameter is acquired according to the line type variation of
the two group parameters, as shown in following figure

By means of setti ng the proportion factor and integration time of the speed regulator, the speed dynamic
response of vector control can be regulated. Increasing the proportional gain,and reducing the integration
time, can equally qui cken the dynamic response of speed loop,but either the proportional gain being too
much or the integration time being too short can easily cause system oscillation and too big overshoot. The
proportional gain being too small als o can lead to system steady state oscillation and possibility of speed
steady-state error oc curring
S peed loop PI parameters have an intimate relation with the inertia of motor system, and therefore based
on the default PI parameter the user needs to make adjustment for different loading character in order t o
mee t different requirement.

The slip compensating factor is used to adjust the slip frequency of vector control and improve the
system s peed control accuracy. P roperly regulating this parameter can effectivel y restrain the speed
