Detailed instruction of parameters
example, the strain PID control during wrapup
1:PID output is negative:When the feedback signal is
stronger than the PID given value, the output
frequency of the inverter will increase to balance the
PID. For example, the strain PID control during
wrapdown
The function is applied to the proportional gain P of
PID input.
P determines the strength of the whole PID adjuster.
The parameter of 100 means that when the offset of
PID feedback and given value is 100%, the adjusting
range of PID adjustor is the Max. Frequency
(ignoring integral function and differential function).
The setting range:0.00~100.00
This parameter determines the speed of PID
adjustor to carry out integral adjustment on the
deviation of PID feedback and reference.
When the deviation of PID feedback and reference is
100%, the integral adjustor works continuously after
the time (ignoring the proportional effect and
differential effect) to achieve the Max. Frequency
(P00.03) or the Max. Voltage (P04.31). Shorter the
integral time, stronger is the adjustment
Setting range: 0.00~10.00s
This parameter determines the strength of th e
change ratio when PID adjustor carries out integral
adjustment on the deviation of PID feedback and
reference.
If the PID feedback changes 100% during the time,
the adjustment of integral adjustor (ignoring the
proportional effect and differential effect) is the Max.
Frequency (P00.03) or the Max. Voltage (P04.31).
