Description:
A system is needed which will track the position of a bi-directional linear-motion platform
and allow the user to select a home or zero position. The display should read in inches
and indicate the position of the platform at all times.

Display should increment 50 linear yards for each Reference Count, parameter
21. Because the initial values were 28.3 revolutions per 50 linear yards, each is
multiplied by 10 to give an even number to increase accuracy since the display can be
programmed in whole numbers.
In count mode, the Reference RPM is set in revolutions. 283 has been entered here to
represent 28.3 revolutions and the Display Reference has also been multiplied by 10 to
yield whole numbers.
Pulses per revolution of shaft encoder or pickup is 10 PPM
Note: Needs to be set to zero to get Count Mode to work
Alarm active when display value is above upper limit
Constant alarm output with manual reset required
No silencing, reset on any button press
Upper limit setting for 1500 linear yards.
