terminal is invalid, and select PID parameter group 2 when the terminal is valid.
2: Switch according to deviation
selects parameter group 1; when the absolute value of deviation between PID given and feedback is greater than [F13.19 When the PID parameter selects
parameter group 2; when the absolute value of the deviation between the PID reference and the feedback is between the switching deviation low value
[F13.18] and the switching deviation high value [F13.19], the PID parameter is two The linear interpolation value of the group PID parameters is shown in
the figure below.

Differential limiting is used to set the range of the PID differential output. In the PID regulator, the effect of the differential is sensitive, and it is easy to cause
the system to oscillate. Generally, the effect of PID differentiation is limited to a small range.
