After setting each code, set bA.20 (Auto tuning) to 1 (All - rotation type) or 2 (All -
static type) and run auto tuning. Because rotation type auto tuning is more accurate
for 1[(All(Rotation type)] than 2[(All(Static type)], set 1[(All(Rotation type)] and run auto
tuning if the motor can be rotated.
Excitation Current
A motor can be operated only after magnetic flux is generated by current flowing through
a coil. The power supply used to generate the magnetic flux is called the excitation
current.
The stator coil that is used with the inverter does not have a permanent magnetic flux, so
the magnetic flux must be generated by supplying an excitation current to the coil before
operating the motor.
