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

P09.02
PID feedback source
Select the PID channel by the parameter.
0: AI1
1: AI2
2: AI3
3: HDI
4: Modbus communication feedback
5: PROFIBUS/CANopen communication feedback
6: Ethernet communication feedback
7: Reserved
Note: The reference and feedback channel cannot
coincide, otherwise, PID cannot control effectively.

P09.03
PID output feature
0: PID output is positive: when the feedback signal
exceeds the PID given value, the output frequency of
the VFD will decrease to balance the PID. For
example, the strain PID control during winding.
1: PID output is negative: When the feedback signal
is stronger than the PID given value, the output
frequency of the VFD will increase to balance PID.
For example, the strain PID control during
unwinding.

P09.04
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 and differential function).
Setting range: 0.00–100.00
1.00

P09.05
Integral time (Ti)
This parameter 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 proportional effect and
differential effect) to achieve max. output frequency
