It is used to select the feedback channel of PID
Feedback value of process PID is a relative value, set range is 0.0%~100.0%.

：
If the feedback signal is smaller than the PID reference signal, it is required to boost
the output frequency of the inverter to make PID reach balance. The winding tension PID control is such a
case.
Negative action
：
If the feedback signal is smaller than the PID reference signal, it is required to
decrease the output frequency of the inverter to make PID reach balance.The unwinding tension PID
control is such a case.
This function is influenced by function 35,please pay attention during operation.
FA.04 PID reference feedback range 0~65535 1000
☆
PID reference feedback range is a dimensionless unit which is used to display U0.15 PID setup and
U0.16 PID feedback.
PID reference feedback related to the value 100.0%, corresponding to a given feedback range FA.04.If
FA.40 is set to 2000,PID is set to 100.0%,PID given display U0.15 is 2000.

：
the parameter determines the adjustable strength of PID regulator. The larger
P is, the greater the adjustable strength will be.When the parameter is set to 100.0, it means that when the
deviation between PID feedback value and reference value is 100.0%, the range for the PID regulator to
regulate the output frequency commands is the maximum frequency (integration effect and differential
effect are omitted).
Integration time Ti
1
：
determines the strength of PID integration regulation. The shorter the integration
time , the greater adjustable strength will be.Integration time means that when the deviation between PID
feedback value and reference value is 100%, the adjustment by the integration regulator (proportional
effect and differential effect are omitted) after continuous adjustment in this period reaches the maximum
frequency.
Differential time Td
1
：
determines the degree of adjustment that PID regulator performs on the
derivation between PID feedback value and reference value.Differential time means that if the feedback
value changes100% within this time, the adjustment by the differential regulator (proportional effect and
differential effect are omitted) will reach the maximum frequency.The longer differential time is, the higher
the degree of adjustment will be.
FA.08
PID cutoff frequency of
reverse rotation
0.00~maximum frequency 2.00Hz
☆
In some cases, only when the frequency of the PID output is negative (i.e., frequency inversion ) could
PID put the reference and feedback to the same state. High inversion frequency is not allowed in some
certain cases, FA.08 is used to determine reverse frequency upper limit.
