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):
In the integral control mode, the output of the controller is proportional to the integral
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
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.

The PID setting depends on the digital PID setting (F09.01), and the specific
percentage is F09.01/F09.03 * 100.00%.
