Function
Kp Proportional coefficient of PI flux regulator for motor n.1
(P165 and P172 relate to motors 2 and 3).
The regulator’s structure is as follows:
error = Set_Point – Measure;
integral_status = integral_status + error *Ki*Ts;
Output = Kp*error + integral_status;
where Kp is the proportional coefficient
Ki is the integral coefficient = 1/Ti , where Ti is the integral time
Ts
is the regulator operating time (ranging from 200 to 400 microseconds
based on carrier frequency).

Function
Ti Integral time of flux regulator PI for motor n.1
(P166 and P173 relate to parameters 2 and 3).
The regulator’s structure is as follows:
error = Set_Point – Measure;
integral_status = integral_status + error *Ki*Ts;
Output = Kp*error + integral_status;
where Kp is the proportional coefficient
Ki is the integral coefficient = 1/Ti , where Ti is the integral time
Ts
is the regulator operating time (ranging from 200 to 400 microseconds based
on carrier frequency).
NOTE
Parameters P159-P166-P173 are automatically recomputed and saved whenever the
Rotor Time Constant parameter (C025) is changed.
