The high-speed counter module counts 1-phase and 2-phase pulse inputs as
described below.
1-phase pulse input multiplied by one............Counts on the leading edge or trailing
edge of a pulse.
1-phase pulse input multiplied by two ............Counts on the leading edge and trailing
edge of a pulse.
2-phase pulse input multiplied by one............Counts on the leading edge or trailing
edge of a phase A pulse.
2-phase pulse input multiplied by two ...........Counts on the leading edge and trailing
edge of a phase A pulse.
2-phase pulse input multiplied by four............Counts on the leading edge and trailing
edge of phase A and phase B pulses.

Only the AJ65BT-D62D-S1 accepts one input and provides one coincidence
output. However, it can use two points for the counter value magnitude
comparison (coincidence, greater, less) signals.
*
1) Pulses input to the high-speed counter module are counted.
2) The preset or counter function can be selected with an external control signal.
3) The pulse is compared as a coincidence output with the present count value
and a signal is issued accordingly.
4) The sequence program can be used to confirm the I/O signals and remote
register status of the high-speed counter module and to start, stop and preset
the counter.

1.1 Features
The high-speed counter module has the following features.
(1) Pulses can be counted in a wide range from 0 to 16777215.
The count value is stored in 24-bit binary.
(2) Count value can be multiplied.
Multiplication by either one or two can be selected for 1-phase pulse inputs, or
multiplication by one, two or four for 2-phase pulse inputs.
(3) Maximum counting speed can be switched.
Since the maximum counting speed of either 400k (200k for the D62) or 10k can
be selected, pulses can be counted without errors on gentle leading and trailing
edges.
(4) Coincidence output is available.
ON/OFF signals are issued according to the comparison between the preset
output status of a selected channel and the present counter value.
One module can accept two inputs and issues two outputs to one input, which can
serve as upper and lower limit signals.
The AJ65BT-D62D-S1 accepts one input and provides one coincidence output.
Note that it can use two points for counter value (coincidence, greater, less)
signals.
(5) Ring counter function is available.
Counting repeats between the preset value and the ring counter value, and this
function is effective in controlling fixed-pitch feed.
(6) Four counter functions are available.
Any of the following functions can be selected and used.
(a) Latch counter function ........................... Latches the present counter value in
response to an input signal.
(b) Sampling counter function ..................... Counts incoming pulses within the
preset period of time starting from a
signal input.
(c) Periodic pulse counter function ............. Stores the present and previous
counter values at preset intervals
during a signal input.
(d) Count disable function ........................... Stops pulse counting with an input
signal entered while the count enable
command is on.
(7) The preset function or counter function selection can be executed using external
control signals.
(a) Applying voltage to the PRESET (Preset) terminal executes the preset
function.
(b) Applying voltage to the F.START (Function start) terminal executes counter
function selection and the selected function.
These functions are used to eliminate the influence of scan time.

(2) Limitations for use of dedicated command (RLPA, RRPA) for CC-Link
The dedicated command (RLPA, RRPA) for CC-Link may not be used depending
on the programmable controller CPU and the master module.
For details of limitations, refer to the A series master module user's manual
(Detail) and the AnSHCPU/AnACPU/AnUCPU programming manual (Dedicated
command).
Dedicated commands other than RLPA and RRPA cannot be used on the high-
speed counter module.
Refer to Section 10.5 for a program example using dedicated command (RLPA,
RRPA).
