FA.24
Output deviation reverse
maximum value
0.00%~100.00%
1.00%
☆
FA.23 and FA.24 correspond to the output deviation maximum absolute value of forward running and
reverse running respectively.
FA.25 PID integration attribute

：
Integration separation
If integration separation valid, then when the multi-function digital DI integration suspended (function
22) effective, the PID integration stop operation, and only proportion and differential function effectively.
If integration separation invalid, regardless of validity of multi-function digital DI ,integration separation
is invalid.
10bit
：
Whether stop integration when reaching output limit
When PID operation output reaches the maximum or minimum value, user could choose whether to
stop integration or not.
If you choose to stop integration, then the PID integration stops calculation, which may contribute to
the reduction of PID overshoot.
FA.26
PID feedback loss detection
value
No judging 0.0%
0.0%
☆
0.1%~100.0% 0.1%
FA.27
PID feedback loss detection
time
0.0s~20.0s
0s
☆
This function is used to judge if PID feedback has been lost.
When PID feedback value is less than FA.26 set value, and lasted for more than FA.27 set value,
inverter fault alarm. Fault No. 31= Err31.
FA.28
PID stop operation
Stop without operation 0
0
☆
Stop with operation 1
It is used to select if PID keeping operation under PID stop status. Generally FA.28=0 in stop status.
5.13 Swing frequency, fixed length and counting
：
Fb.00-Fb.09
The swing frequency function is applicable to textile and chemical fiber industries and
applications where traversing and winding functions are required.
Swing frequency means that the inverter output frequency swings up and down with the
setup frequency as the center, and the trace of running frequency at the time axis is as shown in
Fig. 5-28.The swing amplitude is set by Fb.00 and Fb.01.
When Fb.01 is set to 0, it means the swing amplitude is 0, and the swing frequency is invalid.
