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 servo amplifier's heat radiating fins, 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 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, servomotor and regenerative resistor with the combi-
nations listed in the instruction manual. Other combinations may lead to fire or faults.
If safety standards (ex., robot safety rules, etc.,) apply to the system using the Motion controller,
servo amplifier and servomotor, 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 servomotor 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.
