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.
If the motor is able to disengage the load, in order to obtain a better operating
performance, you can choose comprehensive auto tunning; otherwise, you can only select
parameters still auto tunning. Firstly set the parameter according to load condition, and
then press RUN key, the inverter will perform parameters auto tunning. Parameters auto
tunning 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 tunning.
1: asynchronous motor parameters still auto tunning
Motor type and motor nameplate parameters b0.00 to b0.05 must be set correctly
before performing asynchronous motor parameters still auto tunning. The inverter can
obtain b0.06 to b0.08 three parameters before performing asynchronous motor parameters
still auto tunning.
2: asynchronous motor parameters comprehensive auto tunning
During asynchronous motor parameters comprehensive auto tunning, the inverter
firstly performs parameters still auto tunning, 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 tunning.
Before preforming asynchronous motor parameters comprehensive auto tunning, not
only motor type and motor nameplate parameters b0.00 to b0.05 must be set properly, but
also encoder type and encoder pulses b0.29, b0.28.
For asynchronous motor parameters comprehensive auto tunning, the inverter can
obtain b0.06 to b0.10 five motor parameters, as well as the AB phase sequence b0.31 of
encoder, vector control current loop PI parameters F5.12 to F5.15.
