The set target of process PID is a relative
value, for which 100% equals 100% of the
feedback signal of the controlled system.
The system always performs calculation by
using a relative value (0
–100.0%).
Note: Multi-step running can be realized by
setting P10 group parameters.
P09.01
PID value
reference
The function code is mandatory when
P09.00=0. The basic value of the function code
is the feedback of the system.
Setting range:-100.0%

P09.02
PID
feedback
source
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: MAX (|AI2|, |AI3|)

–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 VFD will decrease to
balance the PID. For example, the strain PID
control during wrapup
1: PID output is negative: When the feedback
signal is stronger than the PID reference value,
the output frequency of the VFD will increase to
0
