1.4 NOTE
NOTE
- 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 °
°°
°C).
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 the top.
- 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 power cable.
- Do not conduct dielectric strength or insulation test for a sensor.
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
IEC60034 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.
- Use a motor under an appropriate environmental condition.
Using a motor in an adverse environment may cause a failure or
trouble in it. Refer to their respective specification manuals for details
of the operating and environmental conditions for motors.
