6. Description of Parameters
- 106 -
Function Code Parameter Name Setting Range Default
FA-08
PID output limit in
reverse direction
0.00 Hz to max. frequency 2.00 Hz
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 Setting Range Default
FA-09
PID error limit 0.0% to 100.0% 0.0%
FA-09: This function helps to make the AC drive output accurate and stable.
Function Code Parameter Name Setting Range Default
FA-10
PID differential limit 0.00% to 100.00% 0.10%
FA-10 applies a limit to PID differential output as a large output can cause excessive
system oscillation.
Function Code Parameter Name Setting Range Default
FA-11
PID reference change time 0.00s to 650.00s 0.00s
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 Setting Range Default
FA-12
PID feedback lter time 0.00s to 60.00s 0.00s
FA-13
PID output lter time 0.00s to 60.00s 0.00s
FA-12 filters the PID feedback, which helps to lower interference on PID feedback but
slows system response performance.
FA-13 lters the PID output frequency, which helps to drop off mutation of the AC drive
output frequency but slows system response performance.
