Description of Function Codes
Function Code
PA-02 PID feedback source
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
PA-03 PID action direction
• 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
PA-04
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 PA-04. If PA-04 is
set to 2000 and PID setting is 100.0%, the PID setting display (U0-15) is 2000.
Function Code
PA-05 Proportional gain Kp1
PA-06 Integral time Ti1
PA-07 Differential time Td1
