operator of this. Since tuning cannot be done while the web is stopped, the Spyder automatically returns to the
Tuning Menu when the web is stopped. Make sure to set the position setpoint potentiometer to the midpoint before
restarting after tuning.
NOTE:
Applies to Setpoint Source is Ethernet. The position setpoint can always be changed during tuning either
by Ethernet or by the UP and DOWN arrow keys. The dancer does not need to be stopped to exit the Tuning
screens.
7.5.1
QUICK STABILIZE
– FIRST STEP
Default tuning parameters are embedded in the Spyder and were selected to minimize instability. If the system is
exhibiting extreme fluctuations at start-up, perform the following procedure to quickly stabilize it. Fine-tuning using
“Tuning” will still be required. NOTE: The system must be running to Quick Stabilize.
Navigate to the
Quick Stab
menu and press
.
If the system is unstable then press the arrow key associated with
the "
If Unstable
" text until the system is stable. If the system is stable then press the arrow key associated with the
text "
If Now Stable
" or "
Done
".
Two different types of screens will appear while performing the Quick Stabilize tuning:
See 7.5.1.1 Quick Stabilize, Integrator Test
See 7.5.1.2 Quick Stabilize, Parameter Adjustment
7.5.1.1
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".
7.5.1.2
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:
