1 OVERVIEW

1.1 Features

MELSEC-Q

1

The features of the QD62(ED) are as follows:

(1) Counting can be performed in a wide range (The count value can be

expressed within the range between –2147483648 and 2147483647)

The count values are stored as 2-channel 32-bit signed binary codes.

(2) The maximum counting speed can be ch ang ed

The maximum speed of the QD62D can be changed by selecting from among
500 k, 200 k, 100 k and 10 k, while that of the QD62 and QD62E can be selected
from among 200k, 100k and 10k. This allows an error-free count even with
gradual rise/fall pulses.

(3) Pulse input can be selected

The pulse input can be selected from 1 phase multiple of 1, 1 phase multiple of 2,
2 phase multiple of 1, 2 phase multiple of 2, 2 phase multiple of 4, CW and CCW.

(4) Counter format can be selected

Either one of the following counter formats can be selected.

(a) Linear counter format

A count from –2147483648 to 2147483647 is possible and if the count
exceeds the range , an ov er flow will be detected.

(b) Ring counter format

Counting is performed repeatedly between the ring counter maximum value
and minimum value.

(5) Coincidence output is possible

Any channel coincidence out put point can be preset to co mpare with the present
counter value to output the ON/OFF signal out put, o r to start an int errupt pr ogram.

(6) Selection can be made from four counter functi ons

One of the following four functions can be selected.

(a) Latch counter function

This function latches the present value of the counter when the signal was
input.

(b) Sampling counter function

This function counts the pulses that were input within the preset time period
from the sign al inpu t .

(c) Periodic pulse counter function

This function stores the present and previous values of the counter at each
preset time interval while the signal is being input.

(d) Disable count function

This function i nput s a sig na l whil e e xec u ti ng the cou nt e nabl e command to
stop pulse counting.

1 OVERVIEW

MELSEC-Q

(7) The preset function/counter selection function can be executed

using an external control signal

By applying voltage to the preset terminal/function start terminal of an external
terminal, preset function/counter function selection can be executed.

(8) Easy settings using the utility package

A utility package is sold separately (GX Configurator-CT).
The utility package is not a required item. However, it can be used to set initial
settings and automatic refresh settings onscreen, reduce sequence programs,
and check settings and operating status.

(9) A blown fuse in the external output section can be de tected

A blown fuse in th e e xte r nal ou tput se ctio n can be de te ct ed ; i t is no tified by the

function

The functions can be used in combination. However, only either one of the linear counter function or ring

counter function can be used, and only one of the four counter functions can be selected.

Values from –2147483648 to 2147483647 can be counted. If the
count exceeds the range, this function detects an overflow.
Repeatedly executes counting between the ring counter
maximum and minimum values.
Compares the coincidence output point of any preset channel
with the present counter value, and outputs the ON/OFF signal.
Generates an interrupt signal to the PLC CPU when coincidence
is detected, and starts the interrupt program.
Rewrites the present counter value to any numeric value.
Performs preset using the sequence program or external preset
input.
Stops the pulse count while the count enable command is being
executed.
Stores the present counter value at the time the counter function
selection start command signal is input in the buffer me mory .
Counts the pulses that are input during the preset sampling time
period from the time the counter function selection start
command is input, and stores the count in the buffer memory.
While the counter function selection start command sign al is
being input, stores the present value in the buffer memory at
preset interval.
