Description
0: PID output characteristic is positive: the
feedback signal is larger than PID reference,
which requires the VFD output frequency to
decrease to balance PID, e.g. tension PID
control of winding.
1: PID output characteristic is negative:
feedback signal is larger than PID reference,
which requires the VFD output frequency to
increase to balance PID, e.g. tension PID
control of unwinding.
It determines the regulation intensity of the
whole PID regulator, the larger the P is, the
stronger the regulation intensity is. If this
parameter is 100, it means the regulation
amplitude
made
command by the proportional regulator
(ignoring integral and differential actions) is
the max. frequency (P00.03) when the
deviation between PID feedback quantity and
reference quantity is 100%.
Setting range: 0.00–100.00
It determines the speed of integral regulation
made on the deviation between PID feedback
quantity and reference quantity by PID
regulator. When the deviation between PID
feedback quantity and reference quantity is
100%,
the
regulation

regulation in the time set by P09.05.
The shorter the integral time, the stronger the
regulation intensity.
Setting range: 0.00–10.00s
It determines the intensity of variation
