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.
Before preforming asynchronous motor parameters comprehensive auto tuning, 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 tuning, 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.
11: synchronous motor parameters still auto tuning
Motor type and motor nameplate parameters b0.00 to b0.05 must be set correctly before
performing synchronous motor parameter auto tuning with load. For synchronous motor
parameters auto tuning with load,the inverter can obtain the initial position angle, and this is the
necessary condition of normal operation of synchronous motor, therefore synchronous motor must
perform parameters auto tuning for the first installation and before the initial use.
12: synchronous motor parameters comprehensive auto tuning
During synchronous motor parameters auto tuning without load , the inverter firstly perform
parameters auto tuning with load,and then accelerates up to F0.01 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. Please note that F0.01 must be set to a non-zero value when performing
identification operation.
Before performing synchronous motor parameters auto tuning without load, not only motor
type and motor nameplate parameters b0.00 to b0.05 must be set properly, but also encoder pulses
b0.29, encoder type b0.28, encoder pole-pairs b0.35.
For synchronous motor parameter auto tuning without load,the inverter can obtain not only
b0.11 to b0.14 motor parameters, as well as encoder information b0.30 b0.31 b0.32, b0.33, vector
control current loop PI parameters F5.12 to F5.15.
Note: Motor parameter auto tuning can only be operated under keyboard control mode,under
terminal and communication control mode the auto tuning function is invalid.
