Note:
The reference channel and feedback
channel cannot be duplicate. Otherwise,
effective PID control cannot be achieved.
P09.03
PID output
characteristics
selection
0: PID output is positive. When the feedback
signal is greater than the PID reference value,
the output frequency of the VFD will decrease
to balance the PID. Example: PID control on
strain during unwinding.
1: PID output is negative. When the feedback
signal is greater than the PID reference value,
the output frequency of the VFD will increase
to balance the PID. Example: PID control on
strain during unwinding.

P09.04
Proportional gain
(Kp)
The function is applied to the proportional gain
P of PID input.
P determines the strength of the whole PID
adjuster. The value 100 indicates that when
the difference between the PID feedback
value and given value is 100%, the range
within which the PID regulator can regulate the
output frequency command is the max.

differential function).

P09.05
Integral time (Ti)
It determines the speed of integral regulation
made on the deviation between PID feedback
and reference by PID regulator. When the
deviation between PID feedback and
reference is 100%, the regulation of integral
