To follow each unit and motor
specifications
Securely fix the servomotor to the machine. Insufficient fixing could lead to the servomotor
slipping off during operation.
Always install the servomotor with reduction gear in the designated direction. Failure to do
so could lead to oil leaks.
Structure the rotary sections of the motor so that it can never be touched during o peration.
Install a cover, etc., on the shaft.
When installing a coupling to a servomotor shaft end, do not apply an impact by
hammering, etc. The detector could be damaged.
Do not apply a load exceeding the tolerable load onto the servomotor shaft. The shaft
could break.
Store the motor in the package box.
When inserting the shaft into the built-in IPM motor, do not heat the rotor hi gher than
130°C. The magnet could be demagnetized, and the specifications cha racteristics will not
be ensured.
If the unit has been stored for a long time, always check the operation before starting
actual operation. Please c ontact t he Service Center or Service Station.
CAUTION
(2) Wiring
Correctly and securely perform the wiring. Failure to do so could lead to runaway of the
servomotor.
Do not install a condensing capacitor, surge absorber or radio noise filter on the output side of
the servo drive unit.
Correctly connect the output side (terminals U, V, W). Failure to do so could lead to abnormal
operation of the servomotor.
Do not directly connect a commercial
power supply to the servomotor. Failure
to observe this could result in a fault.
When using an inductive load such as a
relay, always connect a diode as a noise
measure parallel to the load.

When using a capacitance load such as a lamp, always connect a p rotective resistor as a
noise measure serial to the load.
Do not reverse the direction of a diode which connect to a DC relay for the control output
signals to suppress a surge. Connecting it backwards could cause the drive unit to malfunction
so that signals are not output, and emergency stop and other safety circuits are inoperable.
Do not connect/disconnect the cables connected between the units while the power is ON.
Securely tighten the cable connector fixing screw or fixing mechanism. An insecure fixing could
cause the cable to fall off while the power is ON.
When using a shielded cable instructed in the connection manual, always ground the cable with
a cable clamp, etc.
Always separate the signals wires from the drive wire and power line.
Use wires and cables that have a wire diameter, heat resistance and flexibility that conforms to
the system.
CAUTION
(3) Trial operation and adjustment
Check and adjust each program and parameter before starting operation. Failure to do so could
lead to unforeseen operation of the machine.
Do not make remarkable adjustments and chang es as the operation could become unstable.
(4) Usage methods
Install an external emergency stop circu it so that the ope ration can be stopped and power
shut off immediately.
Turn the power OFF immediately if smoke, abnormal noise or odors are generated from the
servo drive unit or servomotor.
Unqualified persons must not disassemble or repair the unit.
Never make modifications.
Reduce magnetic damage by installing a noise filter. The electronic devices used near the
servo drive unit could be affected by magnetic noise.
Use the servo drive unit, servomotor and regenerative resistor with the designated combination.
Failure to do so could lead to fires or trouble.
The brake (magnetic brake) assembled into the servomotor is for holding, and must not be used
for normal braking.
There may be cases when holding is not possible due to the magnetic brake's life or the
machine construction (when ball screw and servomotor are coupled via a timing belt, etc.).
Install a stop device to ensure safety on the machine side.
After changing the programs/parameters or after maintenance and inspection, always test the
operation before starting actual operation.
Do not enter the movable range of the machine during automatic operation. Never place body
parts near or touch the spindle during rotation.
Follow the power supply specification conditions given in the separate specifications manual for
the power (input voltage, input frequency, tolerable sudden power failure time, etc.).
Set all bits to "0" if they are indicated as not used or empty in the explanation on the bits.
Do not use the dynamic brakes except during the emergency stop. Continued use of the
dynamic brakes could result in brake damage.
If a breaker is shared by several power supply units, the breaker may not activate when a
short-circuit fault occurs in a small capacity unit. This is dangerous, so never share the
breakers.
