increase to balance the PID. Example: PID
control on strain during unwinding.
P09.04
Proportional gain
(Kp)
P determines the strength of the whole PID
adjuster. The larger the value of P, the
stronger the adjustment intensity. 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 and differential function) can regulate
the output frequency command is the max.
frequency (P00.03).
Setting range: 0.00
–100.00
10.00

P09.05
Integral time (Ti)
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).
Shorter integral time indicates stronger
adjustment.
Setting range: 0.00
–10.00s
2.00s
○
P09.06 Differential time (Td)
Used to determine the strength of the change
ratio adjustment on the deviation of PID
feedback and reference from the PID
regulator. If feedback quantity changes 100%
during this time period, the range within which
the differential regulator (ignoring integral
function and differential function) can regulate
is the max. frequency (P00.03).
Longer differential time indicates stronger
adjustment.
Setting range: 0.00
–10.00s
1.00s

P09.07
Sampling cycle (T)
Used to indicate the sampling cycle of
feedback. The regulator calculates in each
sampling cycle. A longer sampling cycle
0.100s
