Safety Precautions
General Precautions
DANGER
Never remove covers, cables, connectors, or optional devices while
power is being supplied to the Drive.
Wait for five minutes after turning OFF the power supply and then make
sure that the CHARGE indicator is not lit before starting wiring or
inspection work.
Never touch the power supply terminals while the CHARGE lamp is lit
after turning OFF the power supply, because high voltage may remain in
the Drive.
WARNING
Use a power supply with specifications (number of phases, voltage,
frequency, and AC/DC type) that are appropriate for the product.
Connect the ground terminals on the Drive and Motor to ground poles
according to local electrical codes.
Never damage, pull on, apply excessive force to, place heavy objects on,
or pinch cables.
Never attempt to disassemble, repair, or modify the product.
Make sure that the device in an emergency stop state at any time when
the product has been connected to the machine and ready for the
operation.
Never touch the inside of the Drive.
CAUTION
The Drive heat sinks, regenerative resistors, Motor, and other
components can be very hot while power is ON or soon after the power
is turned OFF. Implement safety measures, such as installing covers, so
that hands and parts such as cables do not come into contact with hot
components.
For the control power supply, use a power supply device with double
insulation or reinforced insulation.
Never use the product in an environment that is subject to water, corrosive
gases, or flammable gases, or near flammable materials.
Never attempt to use a Drive or Motor that is damaged or that has
missing parts.
Install external emergency stop circuits that shut OFF the power supply
and stops operation immediately when an error occurs.
In locations with poor power supply conditions, install the necessary
protective devices (such as AC reactors) to ensure that the input power
is supplied within the specified voltage range.
Use a Noise Filter to minimize the effects of electromagnetic
interference.
Always use a Motor and Drive in one of the specified combinations.
Never touch a Drive or Motor with wet hands.
