D. For Actuator Type, select the type you have.
The actuator is typically equipped with a label that identifies whether
or not it is hydrostatic.
Note If you receive a “Feedback is not responding to drive signal” message
during tuning, select Hydrostatic. This setting allows more and faster
valve movements, which results in more actuator movement.
E. For Upper Limit and Lower Limit, set the upper and lower limits for
actuator travel during auto-tuning.
Auto-tuning exercises the actuator within 80% of these limits.
Automated Controllers:
A. In the Station Manager window, click to open the Auto-Tuning
control panel.
B. For Control Channel, select the channel to be auto-tuned.
C. For Control Mode, select a displacement control mode.
D. For Mode to Tune, select the displacement mode.
E. For Auto-Tuning Type, select Basic, Advanced, or Advanced Only.
Basic provides an adequate level of tuning for most control modes.
Advanced automatically performs Basic auto-tuning followed by a
sweep function that provides a higher level of tuning based on
Tracking% values.
Advanced Only performs only the sweep function (using the
Tracking% values).
F. For Actuator Type, select Normal or Hydrostatic.
For most cases select Normal. If you receive a “Feedback is not
responding to drive signal” message during tuning, select Hydrostatic.
This setting allows more and faster valve movements, which results in
more actuator movement.
