Chap. 9 FUNCTION CODES
Refining the system response waveforms is shown below.
1) Suppressing overshoot
Increase the data value of function code
J04 (integration time) and decrease that
for code J05 (differentiation time)
2) Quick stabilizing (small overshoot allowable)
Decrease the data value of function code
J03 (gain) and increase that for code J05
(differentiation time)
3) Suppressing oscillation longer than the integration time set by function code J04
Increase the data value set to function
code J04 (integration time)
4) Suppressing oscillation of approximately same period as the time set for function code J05
(differentiation time)
Decrease the data value set for function
code J05 (differentiation time).
Decrease the data value set for function
code J03 (gain), even if the
differentiation time is set at 0 sec.
Feedback filter (J06)
Sets the time constant of the filter for PID feedback signals.
- Data setting range: 0.0 to 900.0 (sec.)
- This setting is used to stabilize the PID control loop. Setting too long a time constant makes
the system response slow.
