EDSVS9332K−EXT EN 4.0
Function
l Identical with FB CDATA, but with reduced functionality (cam position profile)
l General characteristic
Selection between general cam position profile and characteristic function
Via CURVEC1−SEL−IN you can select which input (−AIN or −IN) is to be processed.
It is possible to change between a (quasi) analog input (16−bit input) and an input for angle signals
(32 bit input).
Thus it is possible to use the CURVEC function block
l to implement any function within the limits of ±199.99 % (e.g. Vp adaptation)
or
l to implement a mechanical cam function.
)
Note!
The input should be assigned to a FIXED value to avoid an unintentional change to
another input.
Freezing of the output value
With CURVEC1−HOLD = HIGH the output signals remain the same as of the switching instant,
irrespectively of possibly changing input values.
With CURVEC1−HOLD = LOW the outputs are activated again. The output values immediately
change in accordance with the profile function to the input values pending now.
