PID output
characteristics
selection
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.
0
P09.04
Proportional gain
(Kp)
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 on output frequency command
by the proportional regulator (ignoring integral
and differential actions) is the max. output
frequency (P00.03) when the deviation between
PID feedback quantity and reference quantity is
100%.
Setting range: 0.00–100.00
10.00
P09.05
Integral time (Ti)
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 quantity (ignoring
proportional and differential actions) of integral
regulator can reach max. output frequency
(P00.03) through continuous regulation in the
time set by P09.05.
The shorter the integral time, the stronger the
regulation intensity.
