In actual use, the relationship between the target frequency and the main and aux-
iliary frequency sources is set through P0-10.
KD600 has a built-in PID regulator, and with the selection of frequency given cha-
nnel, users can easily realize automatic adjustment of process control, such as
constant temperature, constant pressure, tension and other control applications.

Figure 4-19 Schematic diagram of frequency closed-loop control
When using PID frequency closed-loop control, it is necessary to select the frequ-
ency source P0-06=6: that is, select the PID output frequency. PID related param-
eters are in the PA group function parameters, and the related PID function code
relationship is shown in the figure above.
