[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) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting
operations (such as forward/reverse rotations or upper/lower limit positioning) must be
configured external to the programmable controller.
(2) Machine OPR (Original Point Return) of the positioning function is controlled by two kinds of
data: an OPR direction and an OPR speed. Deceleration starts when the near-point watchdog
signal turns on. If an incorrect OPR direction is set, motion control may continue without
deceleration. To prevent machine damage caused by this, configure an interlock circuit external
to the programmable controller.
(3) When the CPU module detects an error during control by the positioning function, the motion
slows down and stops.
(4) When the programmable controller detects an abnormal condition, it stops the operation and all
outputs are:
• Turned off if the overcurrent or overvoltage protection of the power supply module is activated.
• Held or turned off according to the parameter setting if the self-diagnostic function of the CPU
module detects an error such as a watchdog timer error.
Also, all outputs may be turned on if an error occurs in a part, such as an 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 the MELSEC-L CPU Module User's Manual (Hardware Design,
Maintenance and Inspection).
(5) Outputs may remain on or off due to a failure of a component such as a transistor in an output
circuit. Configure an external circuit for monitoring output signals that could cause a serious
accident.
● In an output circuit, 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.
● 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.
● Configure a circuit so that the external power supply is turned off first and then the programmable
controller. If the programmable controller is turned off 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
each network. Incorrect output or malfunction due to a communication failure may result in an
accident.

[Design Precautions]
WARNING
● When changing data from a peripheral device connected to the CPU module to the running
programmable controller, configure an interlock circuit in the program to ensure that the entire
system will always operate safely. For other forms of control (such as program modification or
operating status change) of a running programmable controller, read the relevant manuals carefully
and ensure that the operation is safe before proceeding. Especially, when a remote programmable
controller is controlled by an external device, immediate action cannot be taken if a problem occurs
in the programmable controller due to a communication failure. To prevent this, configure an
interlock circuit in the program, and determine corrective actions to be taken between the external
device and CPU module in case of a communication failure.
● An absolute position restoration by the positioning function may turn off the servo-on signal (servo
off) for approximately 20ms, and the motor may run unexpectedly. If this causes a problem, provide
an electromagnetic brake to lock the motor during absolute position restoration.

[Design Precautions]
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.
● During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has 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.
[Installation Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
CAUTION
● Use the programmable controller in an environment that meets the general specifications in the
MELSEC-L CPU Module User's Manual (Hardware Design, Maintenance and Inspection). Failure to
do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.
● To interconnect modules, engage the respective connectors and securely lock the module joint
levers. Incorrect interconnection may cause malfunction, failure, or drop of the module.
● Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
● Securely connect an extension cable to the connectors of a branch module and an extension
module. After connections, check that the cable is inserted completely. Poor contact may cause
malfunction.
● When using an SD memory card, fully insert it into the SD memory card slot. Check that it is inserted
completely. Poor contact may cause malfunction.
● Do not directly touch any conductive parts and electronic components of the module or SD memory
card. Doing so can cause malfunction or failure of the module.
[Wiring Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before wiring. Failure to do so
may result in electric shock or cause the module to fail or malfunction.
● After installation and wiring, attach the included terminal cover to the module before turning it on for
operation. Failure to do so may result in electric shock.
A - 4
Page 7
[Wiring Precautions]
CAUTION
● Individually ground the FG and LG terminals of the programmable controller with a ground
resistance of 100 or less. Failure to do so may result in electric shock or malfunction.
● Use applicable solderless terminals and tighten them within the specified torque range. If any spade
solderless terminal is used, it may be disconnected when a terminal block screw comes loose,
resulting in failure.
● Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a
fire or failure.
● Connectors for external devices must be crimped or pressed with the tool specified by the
manufacturer, or must be correctly soldered. Incomplete connections may cause short circuit, fire, or
malfunction.
● Securely connect the connector to the module.
● 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.
● Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact.
● Check the interface type and correctly connect the cable. Incorrect wiring (connecting the cable to an
incorrect interface) may cause failure of the module and external device.
● Tighten the terminal block screws within the specified torque range. Undertightening can cause short
circuit, fire, or malfunction. Overtightening can damage the screw and/or module, resulting in drop,
short circuit, fire, or malfunction.
● When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable
with connector, hold the connector part of the cable. For the cable connected to the terminal block,
loosen the terminal screw. Pulling the cable connected to the module may result in malfunction or
damage to the module or cable.
● Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
● A protective film is attached to the top of the module to prevent foreign matter, such as wire chips,
from entering the module during wiring. Do not remove the film during wiring. Remove it for heat
dissipation before system operation.
● To use the high-speed counter function, ground the shield cable on the encoder side (relay box) with
a ground resistance of 100 or less. Failure to do so may cause malfunction.
● Mitsubishi programmable controllers must be installed in control panels. Connect the main power
supply to the power supply module in the control panel through a relay terminal block.
Wiring and replacement of a power supply module must be performed by qualified maintenance
personnel with knowledge of protection against electric shock. For wiring methods, refer to the
MELSEC-L CPU Module User's Manual (Hardware Design, Maintenance and Inspection).

[Startup and Maintenance Precautions]
WARNING
● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
● Correctly connect the battery connector. Do not charge, disassemble, heat, short-circuit, solder, or
throw the battery into the fire. Also, do not expose it to liquid or strong shock.
Doing so will cause the battery to produce heat, explode, ignite, or leak, resulting in injury and fire.
● Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the terminal block screws or the connector screws. Failure to do so may result in electric
shock.
CAUTION
● Before performing online operations (especially, program modification, forced output, and operating
status change) for the running CPU module from the peripheral device connected, read relevant
manuals carefully and ensure the safety. Improper operation may damage machines or cause
accidents.
● Do not disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire.
● Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone
System) more than 25cm away in all directions from the programmable controller. Failure to do so
may cause malfunction.
● Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may cause the module to fail or malfunction.
● Tighten the terminal block screws and the connector screws within the specified torque range.
Undertightening can cause drop of the component or wire, short circuit, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
● After the first use of the product (module, display unit, and terminal block), the number of
connections/disconnections is limited to 50 times (in accordance with IEC 61131-2). Exceeding the
limit may cause malfunction.
● After the first use of the SD memory card, the number of insertions/removals is limited to 500 times.

1.1 Advantages of Transition to L Series
Advantage 1) Advanced performance of equipments (shortened takt time)
In addition to the processing performance improvement for L series CPU, the processing
speed for L series intelligent function module is also increased, so that the equipment
capability to improve is possible.
Advantage 2) Baseless, flexible composition
The L series does not require a main base unit and can be installed in a minimum space
without restrictions of the base unit size.
Even when a module is added, the number of modules is not constrained by the number of
base slots, therefore the system cost such as addition of an extension base unit can be
suppressed.
Advantage 3) Improved operating efficiency for programming and monitoring
The intelligent function module operation of GX Works2 can be used on the L series
intelligent function module.
Though using the intelligent function module operation of GX Works2 is not required, the
use enables the following and can reduce sequence programs.
• Initial setting is possible without a program.
• The auto refresh setting allows to read/write buffer memory data of intelligent function
module automatically from/to the CPU device memory.
• Checking of the setting status or operating status of intelligent function module is
simplified.
1.2 Precautions for Transition
(1) When replacing the AnS/QnAS series with the L series, be sure to read the manuals of each L
series module and confirm the functions, specifications, and how to use before using the L
series.
(2) After the AnS/QnAS series is replaced with the L series, be sure to verify the operation of the
entire system before the start of operations.

The L60DA4, however, does not support the resolution mode. To use the same digital value that is used for the A1S62DA,
set the scaling upper and lower limit values that match the resolution of the A1S62DA using the scaling function.
–
Since the resolution differs
between AnS series and L series
modules, it needs to be matched
–
using a sequence program, user
range settings, or the scaling
function. (Refer to Appendix 3.)
By setting the same scaling upper
limits and scaling lower limits as the
–
–
–
–
–
resolution of A1S62DA, the same
digital output values as A1S62DA
can be used.
This function can be used on the
GX Works2.

not used, the sampling time can be shortened.
Performs the A/D conversion for analog input values
successively for each channel, and outputs digital output values
upon each conversion.
For each channel, averages A/D conversion values by the
amount of time, and outputs the average value as a digital
value.
For each channel, averages A/D conversion values by the
number of times, and outputs the average value as a digital
value.
For each channel, averages A/D conversion values by the
number of times on a moving of each sampling processing, and
outputs the average value as a digital value.
Extends the input range. By combining this function with the
input signal error detection function, simple disconnection
detection can be executed.
Stores the maximum and minimum values of the digital output
values in the module.
Detects the analog input value which exceeds the setting range.–
Scale-converts the digital output value to the set range of the A/
D conversion scaling upper limit value and A/D conversion
scaling lower limit value. This omits the programming of the
scale conversion.
Logs the digital output value or scaling value (digital operation
value). The data of 10000 points can be logged for each
channel.

*1For the A1S63ADA, the resolution setting can be selected from 1/4000, 1/8000, and 1/12000 for both voltage and current
inputs.
The L60AD2DA2, however, does not support the resolution mode. To use the same digital value that is used for the
A1S63ADA, set the scaling upper and lower limit values that match the resolution of the A1S63ADA using the scaling
function.
Replacement module L60AD2DA2 does not have the simple loop control (function expression) function.
When the simple loop control (function expression) function is used with A1S63ADA, the sequence
program needs to be addressed. (Refer to Section 4.1)
