P09 Group PID control
P09.00
PID
reference
source
selection
When the frequency command selection (P00.06, P00.
07) is 7, the running mode of the inverter is procedure
PID control.
The parameter determines the “set value” during the PID
procures.
0:Keypad digital reference(P09.01)
1:Analog channel AI1 reference
2:Analog channel AI2 reference
5:Multi-stage speed set
6:MODBUS communication set
The setting target of procedure PID is a relative one,
100% of the setting equals to 100% of the response of
the controlled system.
The system is calculated according to the relative value
(0~100.0%).
Note:
Multi-stage speed reference, it is realized by setting P10
0

P09.01
Keypad PID
preset
When P09.00=0, set the parameter whose basic value is
the feedback value of the system.
The setting range:-100.0%~100.0%
0.0%

P09.02
PID feedback
source
Selection
Select the PID channel by the parameter.
1:Analog channel AI2 feedback
4:MODBUS communication feedback
Note: The reference channel and the feedback channel
can not coincide, otherwise, PID can not control validly.

P09.03
PID output
feature
selection
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 wrapup
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
wrapdown
0

Proportional
gain (Kp)
The function is applied to the proportional gain P of PID
input.
