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 PID regulator, the larger the value of P,
the stronger the regulation intensity. If this
parameter is 100, it means when the deviation
between PID feedback and reference is 100%,
the regulation amplitude of PID regulator
(ignoring integral and differential effect) on
output frequency command is the max.
frequency (ignoring integral and differential
actions).
Setting range: 0.00–100.00

P09.05
Integral time
(Ti)
This parameter determines the speed of PID
adjustor to carry out integral adjustment on the
deviation between PID feedback and
reference.
When the deviation between PID feedback and
reference is 100%, the integral adjustor works
continuously after the time (ignoring the
proportional effect and differential effect) to
0.90s
