0: PID output is positive.
When the feedback signal is greater than the PID
reference value, the output frequency of the
inverter will decrease to balance the PID.
Example: PID control on strain during unwinding.
1: PID output is negative.
When the feedback signal is greater than the PID
reference value, the output frequency of the
inverter will increase to balance the PID.
Example: PID control on strain during unwinding.
P determines the strength of the whole PID
adjuster. The value 100 indicates that when the
difference between the PID feedback value and
given value is 100%, the range within which the
proportional regulator (ignoring integral function
(Kp)
and differential function) can regulate the output
frequency command is the max. frequency
(P00.03).
Setting range: 0.00–100.00
Used to determine the speed of the integral
adjustment on the deviation of PID feedback and
reference from the PID regulator. When the
deviation of PID feedback and reference is 100%,
the integral adjuster works continuously during
the time (ignoring proportional and differential
function) to achieve the max. output frequency
(P00.03).
