For Safe Operations
1. Prevention of electric shocks
DANGER
Never open the front case or terminal covers while the power is ON or the unit is running, as this
may lead to electric shocks.
Never run the unit with the front case or terminal cover removed. The high voltage terminal and
charged sections will be exposed and may lead to electric shocks.
Never open the front case or terminal cover at times other than wiring work or periodic
inspections even if the power is OFF. The insides of the module and servo amplifier are charged
and may lead to electric shocks.
Completely turn off the externally supplied power used in the system before mounting or removing
the module, performing wiring work, or inspections. Failing to do so may lead to electric shocks.
When performing wiring work or inspections, turn the power OFF, wait at least ten minutes, and
then check the voltage with a tester, etc. Failing to do so may lead to electric shocks.
Be sure to ground the module, servo amplifier and servomotor (Ground resistance: 100 or
less). Do not ground commonly with other devices.
The wiring work and inspections must be done by a qualified technician.
Wire the units after installing the module, servo amplifier and servomotor. Failing to do so may
lead to electric shocks or damage.
Never operate the switches with wet hands, as this may lead to electric shocks.
Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as this
may lead to electric shocks.
Do not touch the module, servo amplifier, servomotor connector or terminal blocks while the
power is ON, as this may lead to electric shocks.
Do not touch the built-in power supply, built-in grounding or signal wires of the module and servo
amplifier, as this may lead to electric shocks.
2. For fire prevention
CAUTION
Install the module, servo amplifier, servomotor and regenerative resistor on incombustible.
Installing them directly or close to combustibles will lead to fire.
If a fault occurs in the module or servo amplifier, shut the power OFF at the servo amplifier's
power source. If a large current continues to flow, fire may occur.
When using a regenerative resistor, shut the power OFF with an error signal. The regenerative
resistor may abnormally overheat due to a fault in the regenerative transistor, etc., and may lead
to fire.
Always take heat measures such as flame proofing for the inside of the control panel where the
servo amplifier or regenerative resistor is installed and for the wires used. Failing to do so may
lead to fire.
Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as this
may lead to fire.

3. For injury prevention
CAUTION
Do not apply a voltage other than that specified in the instruction manual on any terminal.
Doing so may lead to destruction or damage.
Do not mistake the terminal connections, as this may lead to destruction or damage.
Do not mistake the polarity (+ / -), as this may lead to destruction or damage.
Do not touch the heat radiating fins of module or servo amplifier, regenerative resistor and
servomotor, etc., while the power is ON and for a short time after the power is turned OFF. In this
timing, these parts become very hot and may lead to burns.
Always turn the power OFF before touching the servomotor shaft or coupled machines, as these
parts may lead to injuries.
Do not go near the machine during test operations or during operations such as teaching. Doing
so may lead to injuries.
4. Various precautions
Strictly observe the following precautions. Mistaken handling of the unit may lead to faults,
injuries or electric shocks.
(1) System structure
CAUTION
Always install a leakage breaker on the module and servo amplifier power source.
If installation of an electromagnetic contactor for power shut off during an error, etc., is specified
in the instruction manual for the servo amplifier, etc., always install the electromagnetic contactor.
Install the emergency stop circuit externally so that the operation can be stopped immediately
and the power shut off.
Use the module, servo amplifier, servomotor and regenerative resistor with the correct
combinations listed in the instruction manual. Other combinations may lead to fire or faults.
Use the CPU module, base unit, and Simple Motion module with the correct combinations listed
in the instruction manual. Other combinations may lead to faults.
If safety standards (ex., robot safety rules, etc.,) apply to the system using the module, servo
amplifier and servomotor, make sure that the safety standards are satisfied.
Construct a safety circuit externally of the module or servo amplifier if the abnormal operation of
the module or servo amplifier differs from the safety directive operation in the system.
In systems where coasting of the servomotor will be a problem during the forced stop, emergency
stop, servo OFF or power supply OFF, use the dynamic brake.
Make sure that the system considers the coasting amount even when using the dynamic brake.
In systems where perpendicular shaft dropping may be a problem during the forced stop,
emergency stop, servo OFF or power supply OFF, use both the dynamic brake and
electromagnetic brake.
The dynamic brake must be used only on errors that cause the forced stop, emergency stop, or
servo OFF. This brake must not be used for normal braking.
The brake (electromagnetic brake) assembled into the servomotor are for holding applications,
and must not be used for normal braking.

A - 4
CAUTION
The system must have a mechanical allowance so that the machine itself can stop even if the
stroke limits switch is passed through at the max. speed.
Use wires and cables that have a wire diameter, heat resistance and bending resistance
compatible with the system.
Use wires and cables within the length of the range described in the instruction manual.
The ratings and characteristics of the parts (other than module, servo amplifier and servomotor)
used in a system must be compatible with the module, servo amplifier and servomotor.
Install a cover on the shaft so that the rotary parts of the servomotor are not touched during
operation.
There may be some cases where holding by the electromagnetic brake is not possible due to the
life or mechanical structure (when the ball screw and servomotor are connected with a timing belt,
etc.). Install a stopping device to ensure safety on the machine side.
(2) Parameter settings and programming
DANGER
Set the parameter values to those that are compatible with the module, servo amplifier,
servomotor and regenerative resistor model and the system application. The protective functions
may not function if the settings are incorrect.
The regenerative resistor model and capacity parameters must be set to values that conform to
the operation mode and servo amplifier. The protective functions may not function if the settings
are incorrect.
Set the mechanical brake output and dynamic brake output validity parameters to values that are
compatible with the system application. The protective functions may not function if the settings
are incorrect.
Set the stroke limit input validity parameter to a value that is compatible with the system
application. The protective functions may not function if the setting is incorrect.
Set the servomotor encoder type (increment, absolute position type, etc.) parameter to a value
that is compatible with the system application. The protective functions may not function if the
setting is incorrect.
Use the program commands for the program with the conditions specified in the instruction
manual.
Set the sequence function program capacity setting, device capacity, latch validity range, I/O
assignment setting, and validity of continuous operation during error detection to values that are
compatible with the system application. The protective functions may not function if the settings
are incorrect.

A - 5
DANGER
The input devices and data registers assigned to the link will hold the data previous to when
communication is terminated by an error, etc. Thus, an error correspondence interlock program
specified in the instruction manual must be used.
Use the interlock program specified in the intelligent function module's instruction manual for the
program corresponding to the intelligent function module.
When connecting GX Works2 with the CPU module or connecting a personal computer with an
intelligent function module to modify data of a 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.
For the operating status of each station after a communication failure, refer to the "MELSEC-Q
QD77GF Simple Motion Module User's Manual (Network)". Incorrect output or malfunction due to
a communication failure may result in an accident.
Do not write any data to the "system area" of the buffer memory in the intelligent function module.
Also, do not use any "use prohibited" signals as an output signal from the CPU module to the
intelligent function module.
Doing so may cause malfunction of the programmable controller system.
To set a refresh device in the network parameter, select the device Y for the remote output (RY)
refresh device. If a device other than Y, such as M and L, is selected, the CPU module holds the
device status even after its status is changed to STOP.
If a communication cable is disconnected, the network may be unstable, resulting in a
communication failure of multiple stations. Configure an interlock circuit in the program to ensure
that the entire system will always operate safely even if communications fail.
Failure to do so may result in an accident due to an incorrect output or malfunction.
(3) Transportation and installation
DANGER
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.
