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-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
‡
FA-05 (Proportional gain Kp1)
It decides the regulating intensity of the PID regulator. The higher the Kp1 is, the larger
the regulating intensity is. The value 100.0 indicates when the deviation between PID
feedback and PID setting is 100.0%, the adjustment amplitude of the PID regulator on
the output frequency reference is the maximum frequency.
‡
FA-06 (Integral time Ti1)
It decides the integral regulating intensity. The shorter the integral time is, the larger

is 100.0%, the integral regulator performs continuous adjustment for the time set in FA-
06. Then the adjustment amplitude reaches the maximum frequency.
‡
FA-07 (Differential time Td1)
It decides the regulating intensity of the PID regulator on the deviation change. The
longer the differential time is, the larger the regulating intensity is. Differential time is the
time within which the feedback value change reaches 100.0%, and then the adjustment
amplitude reaches the maximum frequency.
