3.6 Accutune Set Up Group
Introduction
Accutune II automatically calculates GAIN, RATE, and RESET TIME (PID)
tuning constants for your control loop. When initiated on demand, the Accutune
algorithm measures a process step response and automatically generates the
PID tuning constants needed for no overshoot on your process.
Fuzzy Overshoot Suppression, when enabled, will suppress or eliminate any
overshoot that may occur as a result of the existing tuning parameters, as the PV
approaches the setpoint.
