CAUTION
CAUTION
- Keep electronic devices and magnetic media away from any magnet plate.
Bring an electronic device such as a personal computer, camera, or
cellular phone or magnetic media such as a magnetic card or disk near
a magnet plate may cause a failure or damage.
- FANUC motors are designed for use with machines. Do not use them for any
other purpose.
If a FANUC motor is used for an unintended purpose, it may cause an
unexpected symptom or trouble. If you want to use a motor for an
unintended purpose, previously consult with FANUC.
- Ensure that a base or frame on which a motor is mounted is strong enough.
Motors are heavy. If a base or frame on which a motor is mounted is
not strong enough, it is impossible to achieve the required precision.
- Be sure to connect motor cables correctly.
An incorrect connection of a cable cause abnormal heat generation,
equipment malfunction, or failure. Always use a cable with an
appropriate current carrying capacity (or thickness).
- Ensure that motors are cooled if they are those that require forcible cooling.
If a motor that requires forcible cooling is not cooled normally, it may
cause a failure or trouble. For water cooling or air cooling, make sure
that a flow rate is sufficient and the duct is not clogged. For both types,
perform regular cleaning and inspection. When the cooling unit stops
due to a failure or other reason, be sure to interrupt power for the
motor.
- Use caution against leak current.
The amount of leak current flowing through the linear motor may
exceed the value specified in EN60335-1. Take appropriate measures
against leak current by, for example, adopting a structure that prevents
the operator from contacting conductive parts near the motor during
energization.
- Be sure to make thermostat wiring.
Be sure to make thermostat wiring for thermal protection. In addition,
create a ladder or other program to enable thermal protection by the
thermostat.
