For Sate Operations
1. Prevention of electric shocks
WARNING
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 control unit and servo amplifier are
charged and 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.
Always ground the control unit, servo amplifier and servomotor with Class 3 grounding. 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 control unit, 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 control unit, servo amplifier or servomotor terminal blocks while the power
is ON, as this may lead to electric shocks.
Do not touch the internal power supply, internal grounding or signal wires of the control unit
and servo amplifier, as this may lead to electric shocks.
2. For fire prevention
CAUTION
Install the control unit, servo amplifier, servomotor and regenerative resistor on inflammable
material. Direct installation on flammable material or near flammable material may lead to
fires.
If a fault occurs in the control unit or servo amplifier, shut the power OFF at the servo
amplifier's power source. If a large current continues to flow, fires may occur.
When using a regenerative resistor, shut the power OFF with an error signal. The regenera-
tive resistor may abnormally overheat due to a fault in the regenerative transistor, etc., and
may lead to fires.
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 fires.

3. For injury prevention
CAUTION
Do not apply a voltage other than that specified in the user's manual, or the instruction manual for
the product you are using 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.
The servo amplifier's heat radiating fins, regenerative resistor and servo amplifier, etc., will
be hot while the power is ON and for a short time after the power is turned OFF. Do not
touch these parts as doing so 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 control unit and servo amplifier power source.
If installation of a magnetic contactor for power shut off during an error, etc., is specified in
the instruction manual for the servo amplifier, etc., always install the magnetic contactor.
Install an external emergency stop circuit so that the operation can be stopped immediately
and the power shut off.
Use the control unit, servo amplifier, servomotor and regenerative resistor with the combi-
nations listed in the instruction manual. Other combinations may lead to fires or faults.
If safety standards (ex., robot safety rules, etc.,) apply to the system using the control unit,
servo amplifier and servomotor, make sure that the safety standards are satisfied.
If the operation during a control unit or servo amplifier error and the safety direction
operation of the control unit differ, construct a countermeasure circuit externally of the
control unit and servo amplifier.
In systems where coasting of the servomotor will be a problem during emergency stop,
servo OFF or when the power is shut 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 emergency stop,
servo OFF or when the power is shut OFF, use both dynamic brakes and magnetic brakes.
The dynamic brakes must be used only during emergency stop and errors where servo OFF
occurs. These brakes must not be used for normal braking.
The brakes (magnetic brakes) assembled into the servomotor are for holding applications,
and must not be used for normal braking.
Construct the system so that there is a mechanical allowance allowing stopping even if the
stroke end limit switch is passed through at the max. speed.

conform to the operation mode, servo amplifier and servo power unit. 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.
Set the servomotor capacity and type (standard, low-inertia, flat, etc.) parameter to values
that are compatible with the system application. The protective functions may not function if
the settings are incorrect.
