Note: The reference channel and feedback
channel cannot be duplicate. Otherwise,
effective PID control cannot be achieved.
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
tension during unwinding.
The function is applied to the proportional gain
P of PID input.
P determines the strength of the whole PID
adjuster. The larger the value of P, the stronger
the adjustment intensity. 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. frequency (ignoring integral function and
differential function).
Setting range: 0.00–100.00
