In some applications, a group of PID parameters cannot meet the requirements of the entire operation process,
and different PID parameters need to be used in different situations.
This group of parameters is used to switch between two groups of PID parameters. The setting method of the
parameters 10-15~10-17 of the regulator is similar to the parameters 10-05~10-07.
The two sets of PID parameters can be switched through the multi-function input MI terminal l, and can also be
automatically switched according to the deviation of PID.
When switching through the multi-function MI terminal l, the function selection l of the multi-function terminal l
should be set to function 43 (PID parameter switching terminal l), when the terminal l is invalid, select the
parameter group 1 (10-05~10-07), When terminal l is valid, select parameter group 2 (10-15~10-17).
When the automatic switching is selected, the absolute value of the deviation between the given and feedback is
less than the PID parameter switching deviation 1 10-19, PID parameter selection parameter group 1. When the
absolute value of the deviation between the reference and feedback is greater than the PID switching deviation 2
(10-20), PID parameter selection selects parameter group 2.When the deviation between reference and feedback
is between switching deviation 1 and switching deviation 2, the PID parameters are the linear interpolation values
of the two groups of PID parameters, as shown in Figure 5-26.

When the inverter starts, the PID output is fixed at the initial PID value of 10-21, and the PID will start the
closed-loop adjustment operation only after the initial PID holding time of 10-22.
