User Manual of A90 Series Inverter calculation factor are as follows: Proportion (P): Proportional control is one of the simplest control modes. The output of the controller is proportional to the input error signal. When only proportional control is enabled, there are steady-state errors in the system output. Integral (I): of the input error signal. Steady-state errors can be eliminated, so that the system has no steady-state errors while operating in the steady state. However, drastic changes cannot be In the integral control mode, the output of the controller is proportional to the integral tracked. Differential (D):
In the differential control mode, the output of the controller is proportional to the differential (i.e. change rate of the error) of the input error signal. This can predict the trend of changes in errors, quickly respond to drastic changes, and improve the dynamic features of the system in the control process. F09.00=0: digital PID setting F09.01 The PID setting depends on the digital PID setting (F09.01), and the specific percentage is F09.01/F09.03 * 100.00%.
