to within 20% of the Upper Limit and the Lower Limit. This selection
enables Tracking and Sweep Freq.
Advanced Only—When you run Advanced Only auto-tuning, the auto-tuner
skips basic auto-tuning and immediately runs a sine sweep to exercise
the actuator to within 20% of the Upper Limit and the Lower Limit. This
selection enables Tracking and Sweep Freq.
Normal—Uses tuning algorithms for non-hydrostatic actuators. Actuator Type
Hydrostatic—Uses tuning algorithms for hydrostatic actuators.
Sets the limits within which the actuator moves. Upper Limit/ Lower Limit
The Station Manager application stops auto-tuning and trips an interlock
if the actuator exceeds these limits.
Enabled by an Auto-Tuning Type selection of Advanced or Advanced
Only. Tracking
Sets how aggressively Advanced and Advanced Only tuning tunes the
actuator.
The default setting is 50%. Set the Tracking higher to tune the system
“hotter” and lower to tune the system “cooler.”
Tracking values that are too high may produce tuning values that result
in system instability.
Enabled by an Auto-Tuning Type selection of Advanced or Advanced
Only. Sweep Freq
Sets the upper frequency limit of the Advanced and Advanced Only sweep
function. The default setting is 20 Hz.
For successful Advanced and Advanced Only auto-tuning, set the sweep
frequency to create a phase shift greater than 90º for 0% tracking and
135º for 100% tracking between the command and compensated
command.
