First sets a proper rotation inertia ratio of load, and then adjusts gain and integral time
constant of speed loop. The diagram of speed control loop is as the following. To increase the
gain Kv can enhance the speed response bandwidth. To reduce the integral time constant Ti can
increase the system stiffness and reduce the static error.
The speed controller structure can be selected by the value of parameter P018. The 0 and
100 number are stand for IP regulator and 1 to 99 number are stand for PDFF regulator. The
larger the value of parameter P018, the higher frequency response of the system can get. The
smaller the value of the parameter, the higher stiffness (anti-deviation ability) of the system will
be. The medium value takes account to both frequency response and stiffness.
