Specification of high-performance vector convertor
When choosing a multifunction DI terminal switching, multi-function terminal function selection set to 43 (PID parameters
switching terminal), select the parameter set 1 (PA-05 ~ PA-07) when the terminal is invalid, the terminal is valid parameter
set selection 2 (PA-15 ~ PA-17).
Choose to automatically switch between the reference and feedback deviation is less than the absolute value of PID
parameter switching deviation 1 PA-19 when, PID parameter selection parameter set 1. To a deviation between the
reference and the PID feedback is greater than the absolute value of the deviation switch 2 PA-20 Shi, PID parameters select
the parameter set 2. To a deviation between the reference and the feedback is switched when the deviation between 1 and
switching deviation 2, PID parameters for the two sets of PID parameters of the linear interpolation value, as shown in
Figure 6-26.

When the inverter starts, PID PID output is fixed at the initial value PA-21, continuous PID initial value PA-22 after the
holding time, PID loop adjustment operation began.
Figure 6-27 is the initial value of the PID function schematic.
Figure 6-27 is the initial value of the PID function schematic.
This function is used to limit the difference between the two beat PID output (2ms / beat) between the PID output in order to
suppress the change too fast, so that the inverter operation to stabilize.
