This function code is used to select PID
feedback channel.

Note: The reference channel and feedback
channel cannot be duplicate. Otherwise,
effective PID control cannot be achieved.

P09.03
PID output
characteristics
selection
0: PID output is positive. When the feedback
signal is greater than the PID reference value,
the output frequency of the VFD will decrease to
balance the PID. Example: PID control on strain
during unwinding.
1: PID output is negative. When the feedback
signal is greater than the PID reference value,
the output frequency of the VFD will increase to
balance the PID. Example: PID control on strain
during unwinding.

P09.04
High frequency
proportional
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 given value is
100%, the adjusting range of PID adjustor is the
max. frequency (ignoring integral function and
differential function).
Setting range: 0.00–100.00

P09.05
High frequency
integral time (Ti)
This function code 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
0.10s
