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 Motion controller 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 Motion controller, servo amplifier and servo motor. (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 Motion controller, servo amplifier and servo motor. 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 Motion controller, servo amplifier or servo motor 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 Motion controller
and servo amplifier, as this may lead to electric shocks.
2. For fire prevention
CAUTION
Install the Motion controller, servo amplifier, servo motor and regenerative resistor on
incombustible. Installing them directly or close to combustibles will lead to fire.
If a fault occurs in the Motion controller 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.

A - 3
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 controller or servo amplifier, regenerative resistor and servo
motor, 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 servo motor 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 Motion controller 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 Motion controller, servo amplifier, servo motor and regenerative resistor with the correct
combinations listed in the instruction manual. Other combinations may lead to fire or faults.
Use the Motion controller, base unit and 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 Motion controller,
servo amplifier and servo motor, make sure that the safety standards are satisfied.
Construct a safety circuit externally of the Motion controller or servo amplifier if the abnormal
operation of the Motion controller or servo amplifier differ from the safety directive operation in the
system.
In systems where coasting of the servo motor will be a problem during the forced stop, emergency
stop, servo OFF or power supply OFF, use dynamic brakes.
Make sure that the system considers the coasting amount even when using dynamic brakes.
In systems where perpendicular shaft dropping may be a problem during the forced stop,
emergency stop, servo OFF or power supply OFF, use both dynamic brakes and electromagnetic
brakes.

A - 4
CAUTION
The dynamic brakes must be used only on errors that cause the forced stop, emergency stop, or
servo OFF. These brakes must not be used for normal braking.
The brakes (electromagnetic brakes) assembled into the servo motor are for holding applications,
and must not be used for normal braking.
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 Motion controller, servo amplifier and servo
motor) used in a system must be compatible with the Motion controller, servo amplifier and servo
motor.
Install a cover on the shaft so that the rotary parts of the servo motor are not touched during
operation.
There may be some cases where holding by the electromagnetic brakes is not possible due to the
life or mechanical structure (when the ball screw and servo motor are connected with a timing belt,
etc.). Install a stopping device to ensure safety on the machine side.
To maintain the safety of the programmable controller system against unauthorized access from
external devices via the network, take appropriate measures. To maintain the safety against
unauthorized access via the Internet, take measures such as installing a firewall.
(2) Parameter settings and programming
CAUTION
Set the parameter values to those that are compatible with the Motion controller, servo amplifier,
servo motor 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, servo amplifier and servo power supply module. 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.
