Store and use the units under the following environment conditions.
(Note 1) For details, confirm each unit or motor specifications in addition.
(Note 2) -15°C to 55°C for linear servomotor.
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 operation. 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 spindle motor, do not heat the rotor higher than 130°C. The
magnet could be demagnetized, and the specifications characteristics will not be ensured.
Always use a nonmagnetic tool (explosion-proof beryllium copper alloy safety tool: NGK Insulators, etc.)
when installing the linear servomotor.
Always provide a mechanical stopper on the end of the linear servomotor's travel path.
If the unit has been stored for a long time, always check the operation before starting actual operation.
Please contact the Service Center, Service Station, Sales Office or delayer.
(2) Wiring
Correctly and securely perform the wiring. Failure to do so could lead to abnormal operation of the
motor.
Do not install a condensing capacitor, surge absorber or radio noise filter on the output side of the drive
unit.
Correctly connect the output side of the drive unit (terminals U, V, W). Failure to do so could lead to
abnormal operation of the motor.
When using a power regenerative power supply unit, always install an AC reactor for each power supply
unit.
In the main circuit power supply side of the unit, always install an appropriate circuit protector or
contactor for each unit. Circuit protector or contactor cannot be shared by several units.
