Applied Instructions
Pulse + Direction input mode:
Under pulse + direction input mode, both the pulse signal and direction signal are input, the
count value increase/decrease according to the direction signal’s status.

AB phase mode:
U nder AB phase mode, the count value increase/decrease according to the signal difference (A phase
and B phase)

Count Value
High speed counter’s count bound: K-2,147,483,648 ~ K+2,147,483,647. If the count value
exceeds the bound, overflow or underflow will occur; if occur overflow, K+2,147,483,647 will
change to be K-2,147,483,648, then go on counting; if occur underflow, K-2,147,483,648 will
change to be K+2,147,483,647, then go on counting

See the right graph, when M0 is ON, C600 starts to
count with the pulse input from X0 port; when M1
turns from OFF to ON, the status value and count
value of C600 reset.
