6.2.5.2.3 Synchronous motor with reluctance torque
If the inductances Ld and Lq are different, a reluctance torque can be generated by
setting a d-current component (magnetizing current) which amplifies the torque
generated by the magnets.
This effect is particularly pronounced at IPM motors.
Operation with encoder feedback:
The Id-current must be preset depending on the actual set torque of the speed
controller for optimal operation (preferably low motor current).
In this way losses and possible inverter size can be reduced.

The tables are filled by writing on mo00, mo03 and dr99,
ds04. Here, Id is set to 0A and depending on the saturation
coefficients, the current for Iq = f(M) is calculated.

Operation without encoder feedback:
At operation without encoder feedback (SCL), the table mo05 must be filled with
zeros when the high-speed model (ds30) is selected. The optimum apparent cur-
rent is given automatically.
