PowerTune ®Functions PowerTune ® Adaptive Tune modifies PID parameters to eliminate oscillation or drift when load changes occur. Adaptive tune works automatically without disturbing the process. PowerTune ® Pretune gets process up and running quickly and accurately. Optimal pretune performance is achieved by selecting a pretune algorithm appropriate for your process. PowerTune ® Pretune automatically sets: 1) Initial PID parameters 2) Adaptive Tuning parameters 3) Powerback parameters ➤ Four Field changeable output module locations (MA, Relay, SSR, DC, Logic, Loop Power) Rugged...
