General Description
Model D10541-000 Dancer
Position Card, also referred to as a P.I.D. control, is designed
for applications where dancer positioning is used to maintain control of motorized
operations. This card is also suitable for most any type of P.I.D. control
application. The electronic circuitry utilizes the Proportional, Integral, and
Derivative functions to condition the output. Each function can be adjusted
independently to control the amount of change in the output voltage. The output
of the proportional circuit is a voltage level proportional to the dancer and
position inputs. The output of the integral is dependent upon the reference
applied to a 12 bit digital analog converter. The converter allows the circuit
to ratio the reference input and provide a percentage of the reference as output.
An isloated scaling circuit allows optional external voltage scaling of the
integral circuit to condition for diameter or velocity changes. The derivative
circuit adds to the output during changes in the dancer input. The response
and level of the derivative function are independently adjustable to allow for
flexible and stable operation. The output of the proportional, integral, and
derivative are summed together to formulate the final output. This output can
be further modified by an output range potentiometer. A summing input is provided
to allow an
external voltage to be summed directly with the output. A selection is supplied
to change the function, addition or subtraction, of the summing input
as required. Positive, negative, and bipolar connection terminals are also available
for use.
