CHAPTER 1 OVERVIEW
1.1 Overview
This User's Manual describes the specifications, handling, wiring and programming
methods of the Channel Isolated Pulse Input Module (QD60P8-G) used with the
MELSEC-Q series programmable controller CPU.
The QD60P8-G counts the input pulse number (speed, rotation speed, instant flux or
similar) and measures the quantity the length, accumulating flux and so forth. The input
pulse value is updated every 10ms. The QD60P8-G updates the accumulating count
value and the pulse number after movement averaging processing or similar (sampling
pulse number) at intervals of the count cycle setting value.

MELSEC-Q
5) Sampling pulse number indication
The value obtained by performing pre-scale conversion on the pulse
number entered in the count cycle set to the count cycle setting value is
displayed. If the input pulse number is not uniform, movement averaging
processing can be performed to average the input pulse number.
The count range is 0 to 32767.
6) Accumulating count value indication
The accumulating value of the sampling pulse number is displayed in the
set count cycle. The count range is 0 to 99999999, and you can select
whether to use the accumulating counter as the linear counter or ring
counter.
7) Input pulse value indication
The pulse number actually input is displayed every 10ms. Since the input
pulse number is displayed every 10ms, the module can be used as a
counter. (The input pulse value is updated every 10ms. Note this when
using the module as a counter.)
The count range is 0 to 2147483647.
8) Alarm output
It is allowed to set four setting values, i.e. upper/upper limit value,
upper/lower limit value, lower/upper limit value and lower/lower limit value,
for the sampling pulse number to output alarms.
9) Accumulating counter overflow detection
If the accumulating count value overflows (exceeds 99999999) in the linear
counter mode, the accumulating counter overflow detection flag turns ON to
indicate that an overflow error has occurred.
10) Accumulating counter comparison output
If the accumulating count value reaches or exceeds the comparison output
setting value, the accumulating counter comparison flag turns ON.
11) Counter reset
The sampling pulse number, accumulating count value and input pulse
value can be reset at any timing.
(2) Counting speed range of the input pulse can be changed
By changing the input filter, the input pulse speed is available within the range 0
to 30kpps.
(3) 8 channels of pulse inputs in one module
One module has 8 channels of pulse inputs to configure a system at low costs.
(4) Channel isolated
The channels are isolated from each other. (Dielectric withstand voltage:

• Set the number of times to perform movement averaging
processing on the "sampling pulse number" of the buffer

• When "movement averaging processing" is selected in the
"movement averaging processing selection" of the buffer
memory, the initial value of this buffer memory is "0". Therefore,
if you run the programmable controller CPU without setting the
value, a movement averaging setting range outside error (error
code: 300) will occur.
• If the setting value is outside the range, a movement averaging
setting range outside error (error code: 300) occurs. To clear the
error, turn ON the error reset request (Y8 to YF) of the
corresponding channel. After this, set a correct value and then

although they are actually counted.
• If the setting value is outside the range, a pre-scale setting range
outside error (error code: 400) occurs. To clear the error, turn ON
the error reset request (Y8 to YF) of the corresponding channel.
After this, set a correct value and then turn ON the operating

[Setting range: 0 to 32767]
• Stores the accumulating value of the "sampling pulse number" of
the buffer memory.
• The accumulating count value can be used when either the
linear counter or ring counter is selected.
• The accumulating count range is 0 to 99999999 for both the
linear counter and ring counter.
• If the accumulating count value exceeds 99999999 when the
accumulating counter is used as the linear counter, the "overflow
detection flag" of the buffer memory turns ON.
• When the operating condition setting request flag (Y1) is turned
ON or "1" is set in the "counter reset request" of the buffer
memory, the accumulating count value is reset.
• The update timing is the same as the cycle of the sampling pulse
number. (It is the interval set in the "count cycle setting value" of
the buffer memory.")
• Stores the actually entered pulse number.
• This value is not converted into the unit pulse number by the prescale function, unlike the "sampling pulse number" and
"accumulating count value" of the buffer memory.
• The count indication range is 0 to 2147483647.
• When the operating condition setting request flag (Y1) is turned
ON or "1" is set in the "counter reset request" of the buffer
memory, the input pulse value is reset.
• If an overflow error (error code: 100) occurs, this value is kept
counted when the count enable (Y18 to Y1F) is ON.
• The update timing is fixed at 10ms. Therefore, take care when
using the module as a counter.
• If the "accumulating count value" of the buffer memory exceeds
99999999 when the accumulating counter is used as the linear
counter, the overflow detection flag turns ON. At the same time,
an overflow error (error code: 100) occurs and count operation is
stopped.
• When the overflow error has occurred, the accumulating count
value does not change from 99999999 if pulses are input after
the error occurrence. The "sampling pulse number" of the buffer
memory is reset.
• The overflow error is cleared by setting "1" in the "counter reset
request" of the buffer memory. Count operation is resumed after
the error is cleared.
• The error is also cleared by turning ON the error reset request
(Y8 to YF). To resume count operation, however, turn ON the
operating condition setting request flag (Y1) or set "1" in the
counter reset request.

CHAPTER 4 SETUP AND PROCEDURE BEFORE OPERATION
The following describes the procedure prior to the QD60P8-G operation, the name and
setting of each part of the QD60P8-G, and wiring method.
4.1 Handling Precautions
The following are the precautions for handling the QD60P8-G.
(1) Do not drop the module casing, or do not subject it to strong impact.
(2) Do not remove the PCB of each module from its case. Doing so may cause
breakdowns.
(3) Be careful not to let foreign matters such as sawdust or wire chips get inside the
module. These may cause fires, failure and malfunction.
(4) The top surface of the module is covered with a protective film to prevent foreign
objects such as cable offcuts from entering the module when wiring. Do not
remove this film until the wiring is complete.
Before operating the system, be sure to remove the film to provide adequate heat
ventilation.
(5) Tighten the screws such as module fixing screws within the following ranges.
Screw location Tightening torque range
Module fixing screw (M3 screw) *1 0.36 to 0.48N•m
Terminal block screw (M3 screw) 0.42 to 0.58N•m
Terminal block mounting screw (M3.5 screw) 0.66 to 0.89N•m
*1: The module can be easily fixed onto the base unit using the hook at the top of
the module.
However, it is recommended to secure the module with the module fixing
screw if the module is subject to significant vibration.
(6) To mount the module on the base unit, fully insert the module fixing latch into the
fixing hole in the base unit and press the module using the hole as a fulcrum.
Improper installation may result in a malfunction or breakdown of the module, or
may cause the module to fall off.

4.4 Wiring
This section explains how to wire the pulse generator to the QD60P8-G.
The following are the precautions for wiring the QD60P8-G. Read these precautions
together with "Section 4.1 Handling precautions" to ensure work safety.
4.4.1 Wiring precautions
In order to fully utilise the functions of the QD60P8-G and ensure system reliability,
external wiring having a minimum of noise effect must be provided.
The precautions regarding external wiring are described below.
(1) Use separate cables with the AC control circuit and QD60P8-G's external input
signals to avoid the influence of AC side surges and induction.
(2) Do not run the cable close to, or bundle them with, the main circuit and high-
voltage cables and the load cables from other than the programmable controller.
Failure to do so will make the cables susceptible to noise, surges and induction.
(3) If there may be the effect of noise when a cable to be connected to the QD60P8-G
and the power line are installed close to each other, use a general shielded
twisted pair cable as a countermeasure against noise.
The shield must be grounded on the QD60P8-G side.
(4) No soldereless terminals with insulation sleeves can be used on the terminal block.
It is recommended to cover the electric wire connecting section of each solderless
terminal with a marking tube or insulating tube.
(5) The cables connected to the QD60P8-G should be placed in a duct or fixed. Not
doing so can cause the QD60P8-G or cables to be damaged when the cables
swing, move or are pulled carelessly, for example, or to malfunction due to poor
cable connection.

• Overflow error
An overflow error (error code: 100) occurs if the "accumulating count value" of
the buffer memory exceeds 99999999 when the count type is the linear counter.
If the overflow error occurs, count operation is stopped, and the "accumulating
count value" of the buffer memory does not change from 99999999 if pulses are
input. Also, the "sampling pulse number" of the buffer memory is reset.
The overflow error is cleared by setting "1" in the "counter reset request" of the
buffer memory. Count operation is resumed after the error is cleared. The error is
also cleared by turning ON the error reset request (Y8 to YF). To resume count
operation, however, turn ON the operating condition setting request flag (Y1) or
set "1" in the "counter reset request" of the buffer memory.

The input pulse value is not converted into the unit pulse number by the pre-scale
function (refer to Section 5.6), unlike the "sampling pulse number" and
"accumulating count value" of the buffer memory. If an overflow error occurs, the
value is counted when the count enable (Y18 to Y1F) is ON.
The count type of the input pulse value is a ring counter of 0 to 2147483647.

5.6 Pre-scale Function
The pre-scale function converts the input pulse number into the unit pulse
number when its weight per pulse is a fraction.
The pre-scale function converts the input pulse value per count cycle into the unit
pulse number using the following operation formula. The result of conversion is

• Note that if the pre-scale setting value is set to 0, the sampling pulse number
calculated with the above operation formula becomes 0, and it seems as if pulses
are not counted although they are actually counted.
• If the setting value is other than the above values, a pre-scale setting range
outside error (error code: 400) occurs. To clear the error, turn ON the error reset
request (Y8 to YF) of the corresponding channel. After this, set a correct value
and then turn ON the operating condition setting request flag (Y1).
• The settings are reflected on the module by turning ON the operating condition
setting request flag (Y1) after setting the values to the buffer memory.

5.7 Movement Averaging Function
The movement averaging function averages the values of the sampling pulse
number, which were imported in the count cycle (refer to Section 5.1.4), by the
specified number of times to calculate the average value. This function is used
when variations occur in the values of the sampling pulse number.

5.8 Alarm Output Function
With "alarm output function valid" set in the "alarm output selection" of the
buffer memory, the alarm output function outputs an alarm if the "sampling
pulse number" of the buffer memory exceeds the upper/upper limit value or
lower/lower limit value. The alarm is turned OFF if the sampling pulse number
is below the upper/lower limit value or above the lower/upper limit value after
the output of the alarm.
To set the alarm output function, set four points: upper/upper limit value,

5.9 Count Response Delay Time
The count value of the QD60P8-G is delayed for the following reasons. Please take
this into consideration when using the module as a counter.
• A delay occurs due to the scan time of a sequence program at the time of count start
processing using the count enable (Y18 to Y1F).
• A delay occurs due to the control cycle (10ms). A maximum of 20ms (one control
cycle
until the "input pulse value" of the buffer memory is displayed. Similarly, a delay also
occurs at a counter reset request.
The calculation expression of the delay time is as indicated below.
Maximum delay time [ms] = (1 scan time + 20) [ms]
2) delay occurs from when the count enable (Y18 to Y1F) is turned ON/OFF

8 ONLINE MODULE CHANGE
CHAPTER 8 ONLINE MODULE CHANGE
MELSEC-Q
When changing a module online, carefully read the QCPU User's Manual (Hardware
Design, Maintenance and Inspection), section 12.4.1 "Online module change".
This chapter describes the functions of an online module change. Perform an online
module change by operating GX Developer.
POINT
(1) Perform an online module change after making sure that the system outside
the programmable controller will not malfunction.
(2) To prevent an electric shock and malfunction of operating modules, provide
means such as switches for powering off each of the external power supply
and external devices connected to the module to be replaced online.
(3) To prevent an electric shock, always turn OFF the input pulse signal from the
pulse generator connected to the module to be changed online.
(4) After the module has become faulty, the buffer memory contents cannot be
confirmed. Therefore, prerecord the settings (The whole buffer memory
contents that can be written refer to Section 3.4.1).
(5) It is recommended to perform an online module change in the actual system in
advance to ensure that it would not affect the other modules by checking the
following:
• Means of cutting off the connection to external devices and its configuration
are correct.
• Switching ON/OFF does not bring any undesirable effect.
(6) Do not install/remove the module to/from the base unit, or the terminal block
to/from the module more than 50 times after the first use of the product. (IEC
61131-2 compliant)
Failure to do so may cause malfunction.

MELSEC-Q
8.1 Online Module Change Conditions
The programmable controller CPU, MELSECNET/H remote I/O module, GX Developer
and base unit given below are needed to perform an online module change.
(1) Programmable controller CPU
The Process CPU is required.
For precautions for multiple CPU system configuration, refer to the QCPU User's
Manual (Multiple CPU System).
(2) MELSECNET/H remote I/O module
The module of function version D or later is necessary.
(3) GX Developer
GX Developer of Version 7.10L or later is necessary.
GX Developer of Version 8.18U or later is required to perform an online module
change on the remote I/O station.
(4) Base unit
1) When the slim type main base unit (Q3 SB) is used, an online module
change cannot be performed.
2) When the power supply module unnecessary type extension base unit
(Q5
B) is used, online module change cannot be performed for the modules
on all the base units connected.
