Above b0.00 to b0.05 are the motor nameplate parameters, which affects the accuracy of the
measured parameters. Please set up according to the motor nameplate parameters. The excellent
vector control performance needs the accurate motor parameters. The accurate identification of
parameters is derived from the correct setting of rated motor parameters.
In order to guarantee the control performance, please configure your motor according to the
inverter standards, the motor rated current is limited to between 30% to 100% of the inverter rated
current. The motor rated current can be set, but can not exceed the inverter rated current. This
parameter can be used to determine the inverter's overload protection capacity and energy
efficiency for the motor.
It is used for the prevention of overheating caused by the self-cooled motor at low speed , or
to correct for protecting the motor when the little change of the motor characteristics may affect
the changes of the motor capacity.

b0.06 to b0.10 are the asynchronous motor parameters, and generally these parameters will
not appear on the motor nameplate and can be obtained by the inverter auto tuning. Among which,
only three parameters of b0.06 to b0.08 can be obtained by Asynchronous Motor Parameters Still
Auto tuning; however, not only all five parameters but also encoder phase sequence and current
loop PI parameters can be obtained by Asynchronous Motor Parameters Comprehensive Auto
tuning
When modifying the motor's rated power (b0.01) or rated voltage (b0.02), the inverter will
automatically calculate and modify the parameter values of b0.06 to b0.10 , and restore these 5
parameters to the motor parameters of commonly used standard Y Series.
If the asynchronous motor parameters auto tuning can not be achieved on-site, you can enter
the corresponding above parameters according to the parameters provided by the manufacturer.

If the motor is able to disengage the load, in order to obtain a better operating performance,
you can choose comprehensive auto tuning; otherwise, you can only select parameters still auto
tuning. Firstly set the parameter according to load condition, and then press RUN key, the inverter
will perform parameters auto tuning. Parameters auto tuning can be performed only under
keyboard operation mode, is not suitable for terminal operation mode and communication
operation mode.
0: no operation, which prohibits parameters auto tnning.
1: asynchronous motor parameters still auto tuning
Motor type and motor nameplate parameters b0.00 to b0.05 must be set correctly before
performing asynchronous motor parameters still auto tuning. The inverter can obtain b0.06 to
b0.08 three parameters before performing asynchronous motor parameters still auto tuning.
2: asynchronous motor parameters comprehensive auto tuning
During asynchronous motor parameters comprehensive auto tuning, the inverter firstly
performs parameters still auto tuning, and then accelerates up to 80% of the rated motor frequency
according to the acceleration time F0.13, after a period of time, and then decelerates till stop
according to the deceleration time F0.14 to end auto tuning.
