11.3 L_PCTRL_1
This FB is a PID controller and can be used for various control tasks (e.g. as dancer position controller,
tension controller, or pressure controller).
The FB is provides with the following functions:
• Adjustable control algorithm (P, PI, PID)
• Ramp function generator for preventing setpoint step-changes at the input
• Limitation of the controller output
• Factorisation of the output signal
• Vp adaptation
• Integral action component can be switched off
