Name Description Default
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.
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.
Setting range: 0.01
–10.00s
2.00s
P09.06
Differential time
(Td)
It determines the intensity of variation regulation
made on the deviation between PID feedback
quantity and reference quantity by PID regulator.
If the feedback quantity changes by 100% during
the time set by P09.06, the regulation quantity of
differential regulator (ignoring proportional and
integral actions) is the max. output frequency
(P00.03).
The longer the differential time, the stronger the
regulation intensity.
Setting range: 0.00
–10.00s
1.00s
P09.07 Sampling cycle (T)
It means the sampling cycle of feedback quantity.
The regulator calculates once during each
0.100s
