FX0: Select upto four 1 phase
counters with a combined countin
frequenc
of 5kHz or less.
Alternativel
select one 2 phase or
A/B phase counter with a countin
frequenc
of 2kHz or less.
FX0S: When multiple 1-phase
counters are used the sum of the
frequencies must be equal or less
than 14kHz. Onl
1, 2 phase hi
h
speed counter ma
be used at an
one time. When 2 phase counters
are in use the maximum counted
speeds must be equal or less than
14kHz, calculated as (2 ph counter
speed 5 number of counted ed
es)
+ 1 ph counter speeds.
