COMMONLY USED CONFIGURATIONS
If the motor gets overshoot of the speed, increase the value of P, and for
the fine tune, increase the value of I. If the motor is not able to keep the
speed on, because the speed is very “nervous”, decrease the value of P
and for the fine tune decrease the I.
For high dynamic applications, the current loop regulator might be
modified:
Current controller P gain
Current controller I gain
For high dynamic applications, the regulator values could be increased in
order to give stability to the system. For very slow dynamins the regulator
values could be decreased in order to give a better operation in the motor
(e.g. geting a constant torque in applications such as positive
displacement pumps)
Finally, if you have not been able to make the motor work properly, you
should initialize all parameters and retry the process from the beginning
again. Maybe the result of the autotuning was not very good and the drive
was not able to calculate properly the vector position.
