See 7.5.1.2 Quick Stabilize, Parameter Adjustment
7.5.2.1 Quick Stabilize, Integrator Test
This screen is entered if the system is not yet stable, and the integrator was on. The integrator was turned off as
this screen was entered. This checks to see if the integrator is causing the instability.
If the system is still unstable, the integrator is not causing the instability. Pressing

will switch to a screen similar to
7.5.1.2 to stabilize the proportional gain.
If the system is now stable, then the integrator is the cause of the instability (it is now off.) Pressing

provides a
series of screens explaining this.
Press

to turn on the integrator and quick stabilize I. A screen similar to 7.5.1.2 will be used to stabilize I.
7.5.2.2
Quick Stabilize, Parameter Adjustment
If this screen appears press If Unstable

to immediately try to stabilize. Press

or

to reposition the dancer if
necessary. The position setpoint input is not active during tuning. The Spyder automatically steps through several
separate stages in an attempt to stabilize the process.
The
Quick Stab screens are all similar to this one:
Besides
P, the parameter being tuned can also be I . The number next to this letter is not the value of the
parameter. It is there to show the progress of the tuning. Its value can be between 00 and 99. 00 is displayed when
that parameter is as stable as it can be. When the system is stable, press

Done. The Spyder will tell you which
parameter should be retuned such as:
Pressing

will automatically take you to the correct parameter to be retuned. This particular message needs some
comment. Retune P at the present diameter (not at core or full roll) if P was previously tuned at core (full roll) and
this message repeatedly comes up. For large roll builds the system may need to be Quick Stabilized a few times
while a roll is being wound or unwound for the first time.
Note that
Error Limit is not tuned by the tuning screens. Decreasing Error Limit can sometimes stabilize a system,
but increasing it will not usually cause a system to become unstable. If the tuning procedures fail to produce a
stable system it may be necessary to manually decrease the Error Limit parameter. The system can be made less
responsive by decreasing the Error Limit.
