Assignment for high-speed counters
Input assignment for high-speed counters
Assignment for input devices of high-speed counters is set by parameters.
Assignment is determined according to functions set for each channels by parameter.
When using internal clock, assignment is same as 1-phase, 1-count (S/W) and phase A is not used.
Input assignment of high-speed counters is as follows.
A: A phase input
B: Phase B input (direction switch input is however employed in the case of 1-phase 1-count [H/W])
P: External preset input
E: External enable input
