D and Q axis voltage drops
If d-axis and q-axis reactances (voltage drops) are defined, drive calculates the optimal d-axis
current reference based on the reactance values and the motor torque in order to account motor
reluctance torque part. In this way, motor Torque/Current ratio can be increased.
P2.8.5.12 Lsd Voltage Drop ID1757
D-axis reactance voltage drop 2560 = 100%.
Gives the % voltage drop across the stator inductance at nominal current and frequency.
P2.8.5.13 Lsq Voltage Drop ID1758
Q-axis reactance voltage drop 2560 = 100%.
Gives the % voltage drop across the stator inductance at nominal current and frequency.
