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.

4. General Precautions
Always follow the precautions below. Incorrect handling could result in faults, injuries or
electric shocks, etc.
(1) Transportation and installation
CAUTION
Correctly transport the products according to the weights.
Use servomotor’s suspension bolts to transport the servomotor itself. Do not use it to transport the
servomotor after installation onto the machine.
Do not stack the products exceeding the indicated limit.
Do not hold the cables, shaft or detector when transporting the servomotor.
Do not transport the controller or servo drive unit by suspending or holding the connected wires or
cables.
Do not hold the front cover when transporting the servo drive unit, or the front cover could come off,
causing the unit to drop.
Install on a non-combustible place where the unit’s or motor’s weight can be withstood according to
the instruction manual.
The servomotor does not have a complete water-proof (oil-proof) structure. Do not allow oil or water
to contact or enter the motor. Prevent the oil-soaked cutting chips from being accumulated on the
motor.
When installing the motor facing upwards, take measures on the machine side so that gear oil, etc.,
will not enter the motor shaft.
Do not remove the detector from the servomotor. (The detector installation screw is treated with
sealing.)
Do not allow foreign matters, especially, conductive foreign matters such as screws or metal chips,
or combustible foreign matters such as oil, to enter the controller, servo drive unit or servomotor.
Failure to observe this could result in rupture or damage.
Do not get on the product or place heavy objects on it.
Provide appropriate distance between the controller/servo drive unit and inner surface of the control
panel/other devices.
Do not install or operate the controller, servo drive unit or servomotor that is damaged or has missing
parts.

CAUTION
Take care not to cut hands, etc. with the heat radiating fins or metal edges.
Do not block the intake/outtake ports of the servomotor with the cooling fan.
Install the controller’s display unit and operation board unit on the spot where cutting oil will not
reach.
The controller, servo drive unit and servomotor are precision devices, so do not drop or apply
thumping vibration and strong impacts on them.
Hard disk unit is a precision device, so do not drop or apply strong impacts on it.
Store and use the units according to the environment conditions indicated in each specifications
manual.
Securely fix the motor to the machine. The motor could come off during operation if insecurely fixed.
Always install the servomotor with reduction gear in the designated direction. Failure to observe this
could result in oil leaks.
Always install a cover, etc., over the shaft so that the rotary section of the spindle motor cannot be
touched during motor rotation.
When using a coupling connection to the servomotor shaft end, do not apply impacts by
hammering, etc. The detector could be damaged.
Use a flexible coupling when connecting with a ball screw, etc., and keep the shaft core deviation
smaller than the tolerable radial load of the shaft.
Do not use a rigid coupling as an excessive bending load will be applied on the shaft and could
cause the shaft to break.
Do not apply a load exceeding the tolerable level onto the motor shaft. The shaft or bearing could
be damaged.

(2) Items related to wiring
CAUTION
Correctly wire this product. Failure to observe this could result in servomotor runaway, etc.
Do not install a phase advancing capacitor, surge absorber or radio noise filter on the output side of
the servo drive unit.
Correctly connect the output side (terminal U, V, W). The servomotor will not run properly if
incorrectly connected.
Always install an AC reactor per each power supply unit.
Always install an appropriate breaker per each power supply unit. A breaker cannot be shared for
multiple power supply units.
Do not directly connect a commercial power supply to the servomotor. Failure to observe this could
result in faults.
When using an inductive load such as relays, always connect a diode in parallel to the load as a
noise countermeasure.
When using a capacitive load such as a lamp, always connect a protective resistor in series to the
load to suppress rush currents.
Do not mistake the direction of the surge absorption diode to be installed on the DC relay for the
control output signal. If mistaken, the signal will not be output due to fault in the drive unit, and
consequently the protective circuit, such as emergency stop, could be disabled.
