Description
This parameter defines the switchover between two groups of PID parameters.
0: No switchover
No switchover is performed.
1: Switchover by DI
To use this function, the DI must be assigned with function 43 (PID parameter
switchover). If the DI is inactive, parameter group 1 (FA‑05 to FA‑07) is selected. If
the DI is active, parameter group 2 (FA‑15 to FA‑17) is selected.
2: Auto switchover based on deviation
If the absolute value of the deviation between the setting and the feedback is less
than FA‑19 (PID parameter switchover deviation 1), parameter group 1 is selected.
If the absolute value of the deviation between the setting and the feedback is
greater than FA‑20 (PID parameter switchover deviation 2), parameter group 2 is
selected. If the absolute value of the deviation between the setting and the
feedback is between FA‑19 (PID parameter switchover deviation 1) and FA‑20 (PID
parameter switchover deviation 2), the PID parameters are linear interpolation
values of the two sets of PID parameters.
3: Switchover based on running frequency
PID parameters are switched automatically based on the running frequency of the
AC drive.
6: Automatic adjustment based on roll diameter
When the current roll diameter changes between the maximum roll diameter
(B0‑08) and the minimum roll diameter (B0‑09), the PID parameters are the linear
interpolation values of the two sets of PID parameters. The minimum roll
diameter corresponds to parameter group 1 (FA‑05 to FA‑07), and the maximum
roll diameter corresponds to parameter group 2 (FA‑15 to FA‑17).
7: Automatic adjustment based on maximum roll diameter percentage
When the current roll diameter changes between the maximum roll diameter
(B0‑08) x FA‑20 and the maximum roll diameter (B0‑08) x FA‑19, the PID
parameters are the linear interpolation values of the two sets of PID parameters.
