3.8 Macro 5
PID (set-point control)
Features
Specific features
PID control is used for applications where a process
is required to be maintained at a set-point. Typical
applications are as follows:
• Closed-loop tension-control processes
where a dancer-arm is used
• Closed-loop pressure-control systems
Selection can be made between PID and analog
frequency control. When PID control is selected,
the three analog inputs are configured as follows:
• Frequency reference to define the frequency
demand
• PID feedback from the feedback device
• PID reference to define the set-point
The dynamic performance, scaling and range of the
PID control can be adjusted.
Two preset references and an optional software
PID-enable can be used.
Standard features

ramps
• Negative logic for the digital inputs
