ITEMS YOU SHOULD NOTE WHEN USING THE DRIVER
NOTICES ON DESIGN
Always use them under followings conditions:
The driver generates heat. Take extra caution for radiation and use it under the
following conditions.
・
Mount in a vertical position keeping sufficient distance to other devices to
let heat generated by the driver radiate freely.
・
0 to 50
℃
, 95% RH or below (No condensation)
・
No vibration or physical shock
・
No corrosive, inflammable or explosive gas
Use sufficient noise suppressing means and safe grounding.
Any noise generated on a signal wire will cause vibration or improper motion.
Be sure to observe the following conditions.
・
Keep signal and power leads separated.
・
Keep leads as short as possible.
・
Ground motor 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 to the drivers.
・
Please consult our sales office, if you intend to make a voltage resistance
test.
Use a fast-response type ground-fault detector designed for
PWM inverters.
When using a fast-response type ground-fault detector, use one that is
designed for PWM inverters. Do not use a time-delay-type ground-fault
detector.
If this product is utilized in any facility in which human life is
at stake or that may incur material losses, install safety
devices so that accidents will not occur even when the
output control is disabled due to damage.
OPERATIONAL PRECAUTIONS
Never change wiring while the power is active.
Make sure that power is non-active before servicing the products. Failure to
observe this caution may result in electric shock or uncontrollable operation.
Do not touch terminals or inspect products at least 15
minutes after turning OFF power.
・
Even after the power supply is turned OFF, electric charge remains in the
driver. In order to prevent electric shock, perform inspections 15 minutes
after the power supply is turned OFF.
・
Make installation of products not easy to touch their inner electric
components.
