Description of Function Codes
Function Code
PA-12 PID feedback filter time
PA-13 PID output filter time
PA-12 is used to flter the PID feedback, helping to reduce interference on the feedback but
slowing the response of the process closed-loop system.
PA-13 is used to flter the PID output frequency, helping to weaken sudden change of the AC
drive output frequency but slowing the response of the process closed-loop system.

PA-16 Integral time Ti2
PA-17 Differential time Td2

In some applications, PID parameters switchover is required when one group of PID
parameters cannot satisfy the requirement of the whole running process.
These parameters are used for switchover between two groups of PID parameters.
Regulator parameters PA-15 to PA-17 are set in the same way as PA-05 to PA-07.
The switchover can be implemented either via a DI terminal or automatically implemented
based on the deviation.
If you select switchover via a DI terminal, the DI must be allocated with function 43 "PID
parameter switchover". If the DI is OFF, group 1 (PA-05 to PA-07) is selected. If the DI is
ON, group 2 (PA-15 to PA-17) is selected.
If you select automatic switchover, when the absolute value of the deviation between PID
feedback and PID setting is smaller than the value of PA-19, group 1 is selected. When the
absolute value of the deviation between PID feedback and PID setting is higher than the
value of PA-20, group 2 is selected. When the deviation is between PA-19 and PA-20, the
PID parameters are the linear interpolated value of the two groups of parameter values.
