Cam Control
Description of function
The cam programmer function Cam Control is used to
control a set of 8 built-in cam wheels.
On its 8 outputs (representing the 8 wheels), the function
provides the state corresponding to the current position
of the shaft wheels. The cam configuration can be set for
each position, the output state is adjustable. Once the
maximum value has been reached, the cam restarts from
its initial position (output returns to 0).
Connection
Description
Input
Forward ( )
MOVE FORWARD is the input which
is used to control cam progress; it
moves one step forward at each
rising edge (digital status is
changed from 0 to 1).
Input Reverse
( )
MOVE BACKWARD is the input
which is used to control backward
cam movement; it moves one step
backwards at each rising edge
(digital status is changed from 0 to
1).
Input R ( )
RESET (initialization): When this
input is active, the cam is replaced
to its initial position: the POSITION
output will be forced to 0.
Parameter
From the property dialogue box,
you may adjust:
The number of program steps: Its
value is between 1 and 50.
Output status [1..8]: for each
position of the shaft.
Outputs Q 1-8
The status of the 8 outputs
corresponds to the current
position of the shaft (representing
the 8 wheels).
Output Position
An analogue output corresponding
to the current cam position (0 to
49).
