SAFETY GUIDE
For actuators, motors, control units and drivers
manufactured by Harmonic Drive LLC
Read this manual thoroughly before designing the application, installation, maintenance or inspection of the actuator.
Indicates a potentially hazardous
situation, which, if not avoided, could
result in death or serious personal injury. Indicates a potentially hazardous situation, which, if
not avoided, may result in minor or moderate personal
injury and/or damage to the equipment.
LIMITATION OF APPLICATIONS :
The equipment listed in this document may not be used for the applications listed below:
Space equipment Automobile, automotive parts
Aircraft, aeronautic equipment Amusement equipment, sport equipment, game machines
Nuclear equipment Machine or devices acting directly on the human body
Household apparatus Instruments or devices to transport or carry people
Vacuum equipment Apparatus or devices used in special environments
If the above list includes your intending application for our products, please consult us.
Safety measures are essential to prevent accidents resulting in death, injury or damage of the equipment due to
malfunction or faulty operation.
CAUTIONS FOR ACTUATORS AT APPLICATION DESIGNING
Always use under followings conditions:
-Ambient temperature: 0 C to 40 C
-Ambient humidity: 20% to 80%RH (Non-condensation)
-Vibration: Max 24.5 m/S
2
-No contamination by water, oil
-No corrosive or
explosive gas
Follow exactly the instructions in the relating
manuals to install the actuator in the equipment.
-Ensure exact alignment of actuator shaft center and
corresponding center in the application.
Failure to observe this caution may lead to vibration,
resulting in damage of output elements.
CAUTION FOR ACTUATORS IN OPERATIONS
Keep limited torques of the actuator.
-Keep limited torques of the actuator.
-Be aware, that if arms attached to output element hits
by accident an solid, the output element may be
uncontrollable
.
Never connect cables directly to a power supply
socket.
-Each actuator must be operated with a proper driver.
-Failure to observe this caution may lead to injury, fire or
damage of the actuator.
Do not apply impacts and shocks
-
Do not use a hammer during installation
-Failure to observe this caution could damage the
encoder and may cause uncontrollable operation.
Avoid handling of actuators by cables.
-Failure to observe this caution may damage the wiring,
causing uncontrollable or faulty operation.
CAUTIONS FOR DRIVERS AT APPLICATION DESIGNING
Always use drivers under followings conditions:
-Mount in a vertical position keeping sufficient distance
to other devices to let heat generated by the driver
radiate freely.
-Ambient temperature: 0
C to 50 C
-Ambient humidity: less than 95% RH (Non
condensation)
-No contamination by water, oil or foreign matters
-No corrosive, inflammable or explosive gas
Use sufficient noise suppressing means and safe
grounding.
-Keep signal and power leads separated.
-Keep leads as short as possible.
-Ground actuator and driver at one single point, minimum
ground resistance class: D (less than 100 ohms)
-Do not use a power line filter in the motor circuit.
Pay attention to negative torque by inverse load.
–Inverse load may cause damages of drivers.
-Please consult our sales office, if you intent to apply
products for inverse load.
Use a fast-response type ground-fault detector
designed for PWM inverters.
-Do not use a time-delay-type ground-fault detector.
CAUTION FOR DRIVERS IN OPERATIONS
Never change wiring while power is active.
-Make sure of power non-active before servicing the
products.
-Failure to observe this caution may result in electric
shock or personal injury.
Do not touch terminals or inspect products at least
5 minutes after turning OFF power
.
-Otherwise residual electric charges may result in
electric shock.
-Make installation of products not easy to touch their
inner electric components.
Do not make a voltage resistance test.
-Failure to observe this caution may result in damage of
the control unit.
-Please consult our sales office, if you intent to make a
voltage resistance test.
Do not operate control units by means of power
ON/OFF switching.
-Start/stop operation should be performed via input
signals.
Failure to observe this caution may result in deterioration
of electronic parts.
DISPOSAL OF AN ACTUATOR, A MOTOR, A CONTROL UNIT AND/OR THEIR PARTS
All products or parts have to be disposed of as industrial waste.
-Since the case or the box of drivers have a material indication, classify parts and dispose them separately.
