3. Items related to prevention of bodily injury or property damage
CAUTION
Install the controller, drive unit, motor and regenerative resistor on non-combustible material. Installation
directly on or near combustible materials could result in fires.
If any malfunction in the unit is observed, shut off the power at the unit’s power supply side. Continuous
flow of large current could result in fires.
Install an appropriate no fuse breaker (NFB) and contactor (MC) on the power input section of the drive unit
and configure the sequence that shuts the power off upon drive unit’s emergency stop or alarm.
When a breaker is shared for multiple power supply units, the breaker may not function upon short-circuit
failure in a small capacity unit. Do not share a breaker for multiple units as this is dangerous.
Incorrect wiring and connections could cause the devices to damage or burn.
DANGER
When transporting or installing a built-in IPM spindle or linear servomotor, be careful so that your hand or
property will not be trapped in the motors or other metal objects. Also keep the devices with low magnetic
tolerance away from the product.
CAUTION
Do not apply voltages to the connectors or terminals other than voltages indicated in the connection and
setup manual for the controller or specifications manual for the drive unit. Failure to observe this could
cause bursting, damage, etc.
Incorrect connections could cause the devices to rupture or damage, etc. Always connect the cables to the
indicated connectors or terminals.
Incorrect polarity (+ -) could cause the devices to rupture or damage, etc.
Persons wearing medical devices, such as pacemakers, must stay away from this unit. The
electromagnetic waves could adversely affect the medical devices.
Fins on the rear of the unit, regenerative resistor and motor, etc., will be hot during operation and for a while
after the power has been turned OFF. Do not touch or place the parts and cables, etc. close to these
sections. Failure to observe this could result in burns.
Do not enter the machine’s movable range during automatic operation. Keep your hands, feet or face away
from the spindle during rotation.
