The system is calculated according to the
relative value (0–100.0%).
Note: Multi-step speed given, it is realized by
setting P10 group parameters.
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
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 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

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 given
value is 100%, the adjusting range of PID
adjustor is the Max. frequency (ignoring
integral function and differential function).
The setting range:0.00–100.00
1.00

P09.05
Interval
time(Ti)
This parameter determines the speed of PID
adjustor to carry out integral adjustment on
0.10s
