SAFETY GUIDE
5
ITEMS YOU SHOULD NOTE WHEN USING THE DRIVER
CAUTIONS RELATED TO THE DESIGN
Always use drivers under followings conditions.
The driver generates heat. Use under the following conditions while paying
careful attention to the heat radiation.
・
Mount in a vertical position keeping sufficient clearance.
・
0
℃
to 50
℃
, 95%RH or below (No condensation)
・
No vibration or physical shock
・
No dust, dirt, corrosive or inflammable gas
Use sufficient noise suppressing means and safe grounding.
Any noise generated on a signal wire will cause vibration or improper motion.
Conform to the following conditions.
・
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.
Safety measures are essential to prevent accidents resulting
in death, injury or damage of the equipment due to
malfunction or faulty operation.
CAUTIONS FOR USAGE
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.
