In order to ensure the control performance, please set
b0.00~b0.05 with reference to the values on the motor’s
nameplate.
Note:
The motor’s power should match that of the
drive.Generally the motor’s power is allowed to be
lower than that of the drive by 20% or bigger by 10%,
otherwise the control performance cannot be ensured.

Fig. 6-33 Motor’s equivalent circuit
In Fig. 6-33, R1, X1l, R2, X2l, Xm and I0 represent
stator’s
resistance, stator’s leakage inductance, rotor’s resistance,
rotor’s leakage inductance, exciting inductance and
current without load respectively. The setting of b0.07 is
the sum of stator’s leakage inductance and rotor’s
inductance.
The settings of b0.06 ~b0.09 are all percentage values
calculated by the formula below:

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.)
