Note:
PA.00, PA.01 and PA.02 are used to set the motor parameters. In order to ensure the
control performance, please set PA.00PA.02 with reference to the values on the
motor nameplate.
The motor power should match that of the inverter. Generally, the motor power is
allowed to be 20% lower than that of the inverter or 10% higher; otherwise, the control
performance would not be ensured.

Fig. 5-10-1 Motor equivalent circuit
In Fig. 5-10-1, R1, Xl, R2, X2, Xm, and I0 represent resistance of stator, leakage
inductance of stator, resistance of rotor, leakage inductance of rotor, mutual
inductance and current without load respectively. The setting of PA.05 is the sum of
leakage inductance of stator and leakage inductance of rotor.
The PA.04 ~PA.07 settings are all percentage values calculated by the following
formulas:
V: Rated voltage;
I: Motor rated current
