◆PA.00, PA.01 and PA.02 are used to set the motor parameters. In order to ensure the
control performance, please set PA.00~PA.02 with reference to the values on the
motor nameplate.
◆The ac motor power should match that of the ac drive. Generally, the motor power is
allowed to be 20% lower than that of the ac drive or 10% higher; otherwise, the
control performance would not be ensured.
PA.03 No load current
Range: 0.1~999.9A【This value depends on the ac
drive model】
PA.04 Resistance of stator
%R1
Range: 0.00%~50.00%【This value depends on the
ac drive model】
PA.05 Leakage inductance
%X
Range: 0.00%~50.00%【This value depends on the
ac drive model】
PA.06 Resistance of rotor
%R2
Range: 0.00%~50.00%【This value depends on the
ac drive model】
PA.07 Mutual inductance
%Xm
Range: 0.0%~200.0%【This value depends on the ac
drive model】

◆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
