Function Code Parameter Name
FA-08 PID output limit in
reverse direction
FA-08: In some applications a high PID output in reverse direction may introduce adverse
reactions and so a limit need to be applied".
●
When frequency reference setting channel is purely PID reference, FA-08 limits the
output in reverse direction.
●
When frequency reference setting channel is main frequency reference + PID
reference, FA-08 limits the calculation result in reverse direction.
Function Code Parameter Name
FA-09 PID error limit
FA-09: This function helps to make the AC drive output accurate and stable.
Function Code Parameter Name
FA-10
PID differential limit
FA-10 applies a limit to PID differential output as a large output can cause excessive
system oscillation.
Function Code Parameter Name
FA-11 PID reference change time
FA-11 sets time it takes PID reference to change from 0.0% to 100.0%. PID reference
changes linearly based on the time set in this parameter, reducing negative impact of
sudden PID reference change.
Function Code Parameter Name
FA-12 PID feedback filter time
FA-13 PID output filter time
FA-12 filters the PID feedback, which helps to lower interference on PID feedback but
slows system response performance.
FA-13 filters the PID output frequency, which helps to drop off mutation of the AC drive
output frequency but slows system response performance.
