Chapter 5 Function Code
J10
PID Control (Anti Reset Windup)
J10 suppresses overshoot in control with the PID controller. As long as the deviation between the feedback
and the PID command is beyond the preset range, the integrator holds its value and does not perform
integration action.
- Data setting range: 0 to 200 (%)

J11 to J13
PID Control (Select Alarm Output, Upper Level Alarm (AH) and Lower Level Alarm
(AL))
Outputting the absolute value alarm or deviation alarm is possible in the PID control. As an alarm output,
setting of the digital output signal
PID-ALM has to be set to E20 to E24, E27 (data = 42).
J11 specifies the alarm output types. J12 and J13 specify the upper and lower limits for alarms, respectively.
PID control (Select alarm output) (J11)
It sets the alarm type. J11 specifies one of the following alarms available.
