[DESIGN PRECAUTIONS]
WARNING
Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable
controller. Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Configure external safety circuits, such as an emergency stop circuit, protection circuit, and
protective interlock circuit for forward/reverse operation or upper/lower limit positioning.
(2) When the programmable controller detects the following error conditions, it stops the operation
and turn off all the outputs.
• Overcurrent or overvoltage protection of the power supply module is activated.
• The CPU module detects an error such as a watchdog timer error by the self-diagnostic
function.
All outputs may turn on when an error occurs in the part, such as I/O control part, where the
CPU module cannot detect any error. To ensure safety operation in such a case, provide a
safety mechanism or a fail-safe circuit external to the programmable controller. For a fail-safe
circuit example, refer to Chapter 9 LOADING AND INSTALLATION in this manual.
(3) Outputs may remain on or off due to a failure of an output module relay or transistor. Configure
an external circuit for monitoring output signals that could cause a serious accident.
In an output module, when a load current exceeding the rated current or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
A - 1
[DESIGN PRECAUTIONS]
WARNING
Configure a circuit so that the programmable controller is turned on first and then the external power
supply. If the external power supply is turned on first, an accident may occur due to an incorrect
output or malfunction.
For the operating status of each station after a communication failure, refer to relevant manuals for
the network.
Incorrect output or malfunction due to a communication failure may result in an accident.
When controlling a running programmable controller from a peripheral connected to the CPU module
or from a personal computer connected to a special function module, configure an interlock circuit in
the sequence program to ensure that the entire system will always operate safely.
For program modification and operating status change, read relevant manuals carefully and ensure
the safety before operation.
Especially, in the case of a control from an external device to a remote programmable controller,
immediate action cannot be taken for a problem on the programmable controller due to a
communication failure.
To prevent this, configure an interlock circuit in the sequence program , and determine corrective
actions to be taken between the external device and CPU module in case of a communication
failure.
When setting up the system, do not allow any empty slot on the base unit.
If any slot is left empty, be sure to use a blank cover (A1SG60) or a dummy module (A1SG62) for it.
Otherwise, internal parts of the module may be flied in the short circuit test or when an overcurrent or
overvoltage is accidentally applied to the external I/O section.
CAUTION
Do not install the control lines or communication cables together with the main circuit lines or power
cables.
Keep a distance of 100mm or more between them.
Failure to do so may result in malfunction due to noise.
When a device such as a lamp, heater, or solenoid valve is controlled through an output module, a
large current (approximately ten times greater than normal) may flow when the output is turned from
off to on.
Take measures such as replacing the module with one having a sufficient current rating.
After the CPU module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter settings, and/or program size.
Design circuits so that the entire system will always operate safely, regardless of the time.

USER PRECAUTIONS
Precautions for using a CPU module
When a CPU module is used for the first time, data in the CPU module (built-in RAM, device
data) and in the memory card are undefined.
Before writing data (parameters, programs) to the CPU module, clear data in the built-in RAM
using a peripheral (PC memory clear operation) and also clear data using the RESET/L.CLR
switch of the CPU module (latch clear operation).
Precautions for battery
(1) Operating a CPU module after being stored without a battery
When a CPU module is operated again after being stored without a battery, data in the
CPU module (built-in RAM, device data) and a memory card may be undefined.
Before operating the CPU module again, clear data in the built-in RAM using a
peripheral (PC memory clear operation) and also clear data using the RESET/L.CLR
switch of the CPU module (latch clear operation).*
After all data are cleared, write the backed-up data in the CPU module or the memory
card.
(2) Operating a CPU module after being stored over the battery life
When a CPU module is operated again after being stored over the battery life, data in
the CPU module (built-in RAM, device data) and a memory card may be undefined.
Before operating the CPU module again, clear data in the built-in RAM using a
peripheral (PC memory clear operation) and also clear data using the RESET/L.CLR
switch of the CPU module (latch clear operation).*
After all data are cleared, write the backed-up data in the CPU module or the memory
card.
POINT
Make sure to back up each memory contents before storing the programmable
controller.
* For details of the PC memory clear operation using a peripheral, refer to the following manuals.
GX Developer Operating Manual
A6GPP/A6PHP Operating Manual
SW IVD-GPPA Operating Manual
For the latch clear operation using the RESET/L.CLR switch of the CPU module, refer to Section

2.2.2 Software package
(1) GPP function software packages and model name setting at the start-up
The following table shows the GPP function software package that can be used to
create the QCPU-A program, and the programmable controller type setting at startup.
When using SW4D5C-GPPW or later, select the programmable controller type from
Q02(H)-A or Q06H-A according to the CPU to be used.
When using the peripheral devices and GPP function software package of SW3D5CGPPW or earlier, specify the programmable controller type name as "A4U". If "A4U"
is not found in PLC type names, specify "A3A." If both "A4U" and "A3A" are not
found, specify "A3H."
Note that when "A4U" is specified, the available device range is limited.

SYSTEM CONFIGURATION2.
POINT
(1) Old software packages other than listed above cannot be used.
(2) To construct MELSECNET/10 network system with QCPU-A, use the AnU-
compatible GPP function software package (which includes "A4U" in its
programmable controller type name).
A network cannot be constructed with the GPP function software package
which is not compatible with AnU (which does not include "A4U" in its
programmable controller type name).
(3) Communication with GX Developer at 115.2kbps may not be available
depending on the peripheral devices. In such a case, select the lower
communication speed.
(4) When using Q02(H)CPU-A and conventional peripheral devices and setting
the programmable controller type as "A4U," designate the main program
setting to 28k steps or less with parameters. When "Main + parameter" is
written with the programmable controller with the setting of 29k steps or more,
"Cannot communicate with PC" is displayed, and writing to the CPU module is
disabled.
(5) Subprograms cannot be used with Q02(H)CPU-A. When using conventional
peripheral devices and setting the programmable controller type as "A4U," do
not specify any subprograms. If any subprograms are specified, "Cannot
communicate with PC" is displayed.
With Q06HCPU, subprogram 1 can be used, but subprograms 2 and 3
cannot.
When subprogram 2 or 3 is specified, the same message above is displayed.
