0: AI1
1: AI2
2: AI3
3: AI1 – AI2
4: Pulse setting (DI5)
5: Communication setting
6: AI1 + AI2

0
This parameter is used to select the feedback signal channel of process PID.
The PID feedback is a relative value and ranges from 0.0% to 100.0%.
Function Code Parameter Name Setting Range Default
FA-03 PID action direction
0: Forward action
1: Reverse action
0
• 0: Forward action
When the feedback value is smaller than the PID setting, the AC drive's output
frequency rises. For example, the winding tension control requires forward PID action.
• 1: Reverse action
When the feedback value is smaller than the PID setting, the AC drive's output
frequency reduces. For example, the unwinding tension control requires reverse PID
action.
Note that this function is influenced by the DI function 35 "Reverse PID action
direction".
Function Code Parameter Name Setting Range Default
FA-04 PID setting feedback range 0–65535 1000
This parameter is a non-dimensional unit. It is used for PID setting display (U0-15) and PID
feedback display (U0-16).
Relative value 100% of PID setting feedback corresponds to the value of FA-04. If FA-04 is
set to 2000 and PID setting is 100.0%, the PID setting display (U0-15) is 2000.
Function Code Parameter Name Setting Range Default
FA-05 Proportional gain Kp1 0.0–100.0 20.0
FA-06 Integral time Ti1 0.01–10.00s 2.00s
FA-07 Differential time Td1 0.00–10.000 0.000s
