encoders replaced the pre-existing position measuring devices. A 360 count
gray-coded encoder was selected to replace the turret resolver.
The data from
the separate component weighing machine was taken as a binary input into
the control. PLC code was written to decode this data, convert it to floating-point
and allow it to be accessed during the part-program cycle.
A part programme
was written by Robtec which allowed the component weight data to be seen
as a message on the screen and verified by the operator before the program
was allowed to continue.
of each machine, full training on the new control system was provided
for the operators and process engineers.
