Select the PID channel by the parameter.
0:Analog channel AI1 feedback
1:Analog channel AI2 feedback
2:Analog channel AI3 feedback
3:High speed HDI feedback
4:MODBUS communication feedback
5~7:Reserved
Note: The reference channel and the feedback
channel can not coincide, otherwise, PID can not
control effectively.

P09.03
PID output
feature
0: PID output is positive: When the feedback
signal exceeds the PID reference value, the
output frequency of the inverter will decrease to
balance the PID. For example, the strain PID
control during wrap-up
1: PID output is negative: When the feedback
signal is stronger than the PID reference value,
the output frequency of the inverter will increase
to balance the PID. For example, the strain PID
control during wrap-down

P09.04
Proportion
al gain
(Kp)
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 reference value is
100%, the adjusting range of PID adjustor is the
Max. Frequency (ignoring integral function and
differential function).
