Safety Precautions
iii
Caution
Use the amplifier and motor together in the specified combination.
Fire or damage to the device could otherwise result.
Only technically qualified personnel should transport, install, wire, operate, or perform
maintenance and inspection on this device.
Electric shock, injury or fire could otherwise result.
Do not expose the device to water, corrosive or flammable gases, or any flammable
material.
Fire or damage to the device could otherwise result.
Be careful of the high temperatures generated by the amplifier/motor and the
peripherals.
Burn could otherwise result.
Do not touch the radiation fin of the amplifier, the regenerative resistor, or the motor
while the device is powered up, or immediately after switching the power off, as these
parts generate excessive heat.
Burn could otherwise result.
In terms of designing safety systems using the Safe Torque Off function, personnel
who have expertise of relevant safety standard are supposed to do that job with good
understanding of this instruction manual.
Injury or damage to the device could otherwise result.
Please read the User Manual carefully before installation, operation, maintenance or
inspection, and perform these tasks according to the instructions.
Electric shock, injury or fire could otherwise result.
Do not use the amplifier or the motor outside their specifications.
Electric shock, injury or damage to the device could otherwise result.
Regenerative resistor has instantaneous capacity. Contact our offices if the
instantaneous regenerative power could be high as the result of high-inertia moment
or high-velocity rotation.
■ Storage Prohibited
Do not store the device where it could be exposed to rain, water, toxic gases or other
liquids.
Damage to the device could otherwise result.
