Tuning Screens
Tuning allows the operator to optimize tuning parameters by using one button to destabilize the system and another
button to stabilize the system. NOTE: The system must be running to perform Tuning. A typical tuning screen
looks like this:
Press
or
to reposition the dancer if necessary. The position setpoint analog input is not active during tuning.
For setpoint source equal to Ethernet the setpoint can be changed over Ethernet while in tuning mode. Besides
“P” the parameter being tuned can also be “I” or “D”. 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. To optimize press
until the system starts to become unstable.
Then press
until stability is again obtained. When finished tuning press
to exit the screen. The web must be
stopped in order to exit back to the "Tuning" menu when the setpoint source is set to Analog.
NOTE:
Applies to Setpoint Source is Analog. The position setpoint input is not active during tuning. The UP and
DOWN arrow keys are used to change dancer position instead. For this reason, the web must be stopped
(Run/Stop = Stop) and restarted (Run/Stop = Run) to leave the tuning screens. A screen is provided to warn the
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.
