Group Pb: Swing Frequency, Fixed Length And Count - IACDRIVE I5300 Series User Manual

Description of Function Codes
Function Code
PA-25 PID integral property
• Integral separated
If it is set to valid, , the PID integral operation stops when the DI allocated with function
22 "PID integral pause" is ON In this case, only proportional and differential operations
take effect.
If it is set to invalid, integral separated remains invalid no matter whether the DI
allocated with function 22 "PID integral pause" is ON or not.
• Whether to stop integral operation when the output reaches the limit
If "Stop integral operation" is selected, the PID integral operation stops, which may help
to reduce the PID overshoot.
Function Code
Detection value of PID
PA-26
feedback loss
Detection time of PID
PA-27
feedback loss
These parameters are used to judge whether PID feedback is lost.
If the PID feedback is smaller than the value of PA-26 and the lasting time exceeds the
value of PA-27, the AC drive reports Err31 and acts according to the selected fault protection
action.
Function Code
PA-28 PID operation at stop
It is used to select whether to continue PID operation in the state of stop. Generally, the PID
operation stops when the AC drive stops.

Group PB: Swing Frequency, Fixed Length and Count

The swing frequency function is applied to the textile and chemical fiber fields and the
applications where traversing and winding functions are required.
The swing frequency function indicates that the output frequency of the AC drive swings up
and down with the set frequency as the center. The trace of running frequency at the time
axis is shown in the following figure.
