Functions of Input Signals
■
Output Modes in Both Counter and Timer Operations
Sustained control output One-shot control output, set to 0.5 second
Input type Counter output Signal high Signal low
No-voltage Contact The contact turns ON The contact turns OFF
Solid-state The open collector transistor is in the ON state The transistor is in the OFF state
Voltage Both Input signal voltage level is 5 to 30 V Input signal voltage level is 0 to 2 V
Input Counter mode A
(command input)
Counter mode B
(individual input)
Counter mode C
(phase difference)
Timer operation
Count input 1 Count input:
The count value is increased
by one when count input 2
(CP2) voltage goes low. The
count value is decreased by
one when count input 2 (CP2)
voltage goes up.
Addition count input The count value is increased by
one when phase of count input
2 (CP2) is delayed with respect
to phase of count input 1 (CP1).
The count value is decreased
by one when phase of count
input 2 (CP2) is ahead with
respect to phase of count input
1 (CP1).
Start input
Count input 2 Addition/subtraction control Subtraction count input Gate input
Output Mode N
Present value display and outputs are
maintained until reset.
Output Mode F
Present value runs continuously. Outputs
are maintained until reset.
Output Mode C
Present value is placed in reset start status
as soon as preset count is reached; the preset is not actually
displayed. Outputs are one-shot, fixed at 0.5 second, and
operate repeatedly.
Output Mode R
Present value display returns to reset start
status after expiration of one-shot time period. Outputs are
one-shot, fixed at 0.5 second, and operate repeatedly.
