Integral control action setting
The manipulated amount for PID integral action can be limited by setting parameters.
The integral control action can be enabled or disabled (the integral term is held) according to the PID control deviation.
Integral control can be disabled by the signal input. (The integral term value is cleared.)
Integral action limit (Pr.135, Pr.136)
• Use
Pr.135 Integral clamp (positive polarity)
or
Pr.136 Integral clamp (negative polarity)
to limit the manipulated
amount for PID integral action.
Integral control action selection (Pr.485)
• The integral control action can be selected according to the PID control deviation.
• Use
Pr.486 to Pr.489
to set the deviation, and use
Pr.485 Integral control activation
to select the action.
• In the holding period, the integral of the deviation is stopped and the integral term is retained as it is. The manipulated
amount is calculated using the kept integral term value.

The integral of the deviation is valid when "9999" is set in
Pr.488
or
Pr.489
