where n = the number of linear encoder divisions per kilometer.
SPD (FNC 56)
Points to note :
a) When the timed count frame is completed the data stored in D
b) Because this is both a high speed and an interrupt process only inputs X0 to X5 may be
c) Multiple SPD instructions may be used, but the identified source devices S
d) Once values for timed counts have been collected, appropriate speeds can be calculated
where n = the number of encoder pulses per revolution of the encoder disk.
