If motor’s parameters are available, please set
b0.06~b0.09 to the values calculated according to the
above formula. b0.10 is the motor current without
load,the user can set this parameter directly.
If the drive performs auto-tuning of motor’s
parameters,the results will be written to b0.06~b0.10
automatically.After motor power (b0.00) is changed, the
drive will change b0.02~b0.10 accordingly(b0.01 is the
rated voltage of motor,user need to set this parameter by
manual according to the value on the motor’s
nameplate.)

1: Stationary auto-tuning (Start auto-tuning to a
standstill motor)
Values on the motor’s nameplate must be input correctly
before starting auto-tuning

.When
starting auto-tuning to a standstill motor, the stator’s
resistance (%R1), rotor’s resistance (%R2) and the
leakage inductance (%X1) will be detected and written
into b0.06

b0.07 and b0.08 automatically.
2: Rotating auto-tuning
Values on the motor’s nameplate must be input correctly
before starting auto-tuning
(
b0.00
~
b0.05
)
.When
starting a rotating auto-tuning, the motor is in standstill
status at first, and the stator’s resistance (%R1), rotor’s
resistance (%R2) and the leakage inductance (%X1) will
be detected, and then the motor will start rotating,
exciting inductance (%Xm and I0 will be detected. All
the above parameters will be saved in b0.06

b0.05 will be set to 0 automatically.
Auto-tuning procedures:
1). A0.13(Torque boost of motor 1) is suggested to set as
0.
2). Set the parameters b0.00(Rated power),b0.01(Rated
voltage),b0.02(Rated current),b0.03(Rated
frequency),b0.04 (Number of polarities of motor ) and
b0.05(Rated speed) correctly;
3). Set the parameter A0.10 correctly.The setting value
of A0.10 can’t be lower than rated frequency.
4). Remove the load from the motor and check the
Safety when set the parameter b0.11 as 2.
5). Set b0.11 to 1 or 2, press ENTER, and then press
RUN to start auto-tuning;
6). When the operating LED turns off, that means the
auto-tuning is over.
3:Reserved.
Note:
1.When setting b0.11 to 2, Acc/Dec time can be
increased if over-current or over-voltage fault occurs in
the auto-tuning process;
2.When setting b0.11 to 2, the motor’s load must be
removed
first before starting rotating auto-tuning;
3.The motor must be in standstill status before starting
the
