for which 100% equals 100% of the feedback
signal of the controlled system.
The system always calculates a relative value (0–
100.0%).
P09.01
PID digital setting
This parameter is mandatory when P09.00 is set to
0. The reference value of this parameter is the
feedback of the system.
Setting range: -100.0%–100.0%

P09.02
PID feedback
source
This parameter is used to select PID feedback
channel.
0: AI1
1: AI2
2: AI3
3: High-speed pulse HDIA
4: Modbus/Modbus TCP communication
5: PROFIBUS/CANopen/DeviceNet
communication
6: Ethernet communication
7: High-speed pulse HDIB
8: EtherCAT/PROFINET/EtherNet IP
communication
9: Programmable expansion card
10: Reserved
Note: The reference channel and feedback
channel cannot be duplicate. Otherwise, effective
PID control cannot be achieved.

P09.03
PID output
characteristics
0: PID output is positive characteristic: namely, the
feedback signal is larger than the PID reference,
which requires the inverter output frequency to
decrease for PID to reach balance, eg, tension PID
control of winding
1: PID output is negative characteristics: namely
the feedback signal is less than PID reference,
which requires inverter output frequency to
increase for PID to reach balance, eg, tension PID
control of unwinding.

P09.04
Proportional gain
(Kp)
This function code is suitable for proportional gain
P of PID input.
It determines the regulation intensity of the whole
