2. Items related to prevention of fire
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.
3. Items related to prevention of bodily injury or property damage
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
manual for the controller or specifications manual for the drive unit. Failure to observe this could
cause the devices to rupture or 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.
