 A set of PID parameters cannot meet the requirements of the entire running process in some
applications. Use Pr.08-75 to switch to the second group of PID parameter Pr.08-31–Pr.08-33.
The setting method for Pr.08-31–08-33 is the same as that for Pr.08-01–08-03.
 The two sets of PID parameters switch automatically according to the frequency and deviation.
Switch according to the output frequency:
 When the output frequency is between Pr.01-07 and Pr.01-00, the PID parameter is the
linear interpolation value between the two PID parameter groups.
Switch according to the deviation:
 When the deviation absolute value between the set point and feedback is smaller than
Pr.08-76 (PID2 Parameter Switch Deviation 1), the first group PID parameters are used.
 When the deviation absolute value between the set point and feedback is larger than Pr.08-
77 (PID2 Parameter Switch Deviation 2), the second group PID parameters are used.
