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 tunning.
Among which, only three parameters of b0.06 to b0.08 can be obtained by Asynchronous
Motor Parameters Still Auto Tunning; 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 Tunning
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 tunning can not be achieved on-site, you can
enter the corresponding above parameters according to the parameters provided by the
manufacturer.
