slowing the response of the process closed-loop system.
P6.13 is used to filter 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.

These parameters are used for switchover between two groups of PID parameters. P6.18
set parameter switchover condition: 0: No switchover; 1: Switchover via X; 2: Automatic
switchover based on deviation.
Regulator parameters P6.15 to P6.16 are set in the same way as P6.05 to P6.07.
If you select switchover via a DI terminal, the DI must be allocated with function 37 "PID
parameter switchover". If the DI is OFF, group 1 (P6.05 to P6.07) is selected. If the DI is ON,
group 2 (P6.15 to P6.17) is selected.
If you select automatic switchover, when the absolute value of the deviation between PID
