This function can make it earlier to access to the sable stage for PID adjustment. Preset value of PID output
is the relevant percentage of upper limiting frequency [F0.1.21].
When frequency inverter start to operate, first of all, it shall be sped up to the preset frequency of PID, and
operate as closed-loop characteristics after running continually for a while at this point of frequency [F7.0.24].
F7.0.25 1Actual sensor value (range)
corresponding to 100% feedback
Setting range:
0.01~100.00
Factory default: 1.00
F7.0.26 Actual sensor value
corresponding to 0% feedback
Setting range:
-100.00~100.00
Factory default: 0.0
This group of parameter determines the corresponding relationship between feedback percentage and
feedback physical quantity, which determines monitoring the displayed dimension of parameter d0.1.36 and
d0.1.37. Corresponding relationship curve is shown in Figure 7-58.
