G.
For Upper Limit and Lower Limit, set the upper and lower limits for
actuator travel during auto-tuning.
Basic auto-tuning exercises within 80% of these limits.
Advanced and Advanced Only auto-tuning functions exercise the
actuator within 20% of these limits. If the limits are exceeded, the auto-
tuner will quit and trip an interlock.
H. For Advanced and Advanced Only auto-tuning—Set the Tracking%
value.
The 50% default setting is appropriate for most systems.

For Advanced and Advanced Only auto-tuning—Set the Sweep Freq.
The Sweep Freq sets the upper frequency limit of the sine sweep. The
20 Hz default setting is a good starting point.

Always clear the actuator area before pressing the Run button.
