Note:
The reference channel and feedback
channel cannot overlap; otherwise, PID cannot
be controlled effectively.
P09.03
PID output
characteristics
0: PID output is positive characteristic: namely,
the feedback signal is larger than the PID
reference, which requires the VFD 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 VFD 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).

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
achieve the max. output frequency (
) or
the max. voltage (
Shorter the integral time is, stronger the
