2. Items related to prevention of fire
CAUTION
Install the controller, servo drive unit, servomotor 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 input power side.
Continuous flow of large current could result in fires.
Install an appropriate NFB (circuit breaker) and MC (contactor) on the power input section of the
servo 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 servomotors or other metal objects. Also keep the
devices with low magnetic tolerance away from the product.
CAUTION
Do not apply voltages to other than those indicated in the connection manual for the controller or
specifications manual for the servo drive unit. Failure to observe this could cause the devices to
rupture or damage, etc.
Incorrect terminal connections could cause the devices to rupture or damage, etc.
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 servomotor, 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.
