B-65285EN/03 SAFETY PRECAUTIONS
- Do not step or sit on a motor.
If you step or sit on a motor, it may get deformed or broken. Do
not put a motor on another unless they are in packages.
- When storing a motor, put it in a dry (non-condensing) place
at room temperature (0 to 40°
If a motor is stored in a humid or hot place, its components may
get damaged or deteriorated. In addition, keep a motor in such a
position that its shaft is held horizontal and its terminal box is at
- Do not remove a nameplate from a motor.
If a nameplate comes off, be careful not to lose it. If the nameplate
is lost, the motor becomes unidentifiable, resulting in
maintenance becoming impossible.
For a nameplate for a built-in spindle motor, keep the nameplate
with the spindle.
- Do not apply shocks to a motor or cause scratches to it.
If a motor is subjected to shocks or is scratched, its components
may be adversely affected, resulting in normal operation being
impaired. Be very careful when handling plastic portions, sensors,
and windings, because they are very liable to break. Especially,
avoid lifting a motor by pulling its plastic portion, winding, or
- Do not conduct dielectric strength or insulation test for a
Such a test can damage elements in the sensor.
- When testing the winding or insulation resistance of a motor,
satisfy the conditions stipulated in IEC60034.
Testing a motor under a condition severer than those specified in
IEC34 may damage the motor.
- Do not disassemble a motor.
Disassembling a motor may cause a failure or trouble in it.
If disassembly is in need because of maintenance or repair, please
contact a service representative of FANUC.
- Do not modify a motor.
Do not modify a motor unless directed by FANUC. Modifying a
motor may cause a failure or trouble in it.
