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.
