6.4. Synchronous Inductance
Synchronous Inductance represents the average synchronous inductance of the motor (it is an equivalent quantity
that represents the auto and mutual interactions between the phase currents); it is usually low in surface magnets
motors; it can be neglected for the first tuning of the motor, but a wrong value will introduce a phase error
proportional to the load, so the tuning strategies can be either:
 Maximize the torque at a rated current;
 Minimize the current at a rated torque.
Please enter the value zero for the first calibration as shown below (the first start-up has to be done with no-load; in
this case there is no phase error neglecting the inductance).

Since the measurement unit is Henry/10000, the value 100, for example, means 10mH (milliHenry)
