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.

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.
