After introducing the basic parameters motor/drive, it is necessary to
perform an autotuning to calculate the internal parameters of the motor:

After that, check if the motor turns correctly. If the motor turns in the lower
speed irregularly, try to increase the parameter of Back EMF:

The following parameters are used for the starting as well. If the
acceleration ramp is too slow and the motor works irregularly these
parameter must be decreased. If the ramp is very fast, increase the
parameters to provide stability.
If for high speed operation the speed is unstable, the speed loops
regulators could be modified:
