CAUTION
CAUTION
- A magnetic card, magnetic media, computer, etc. should be kept away from the
rotor
An electric or magnetic equipments, such as camera, cellular phone,
magnetic card, etc. might be broken by the leakage flux of the rotor.
- Do not touch the running motor and the motor just after a stop
The running motor is very hot. So, do not touch the motor until the
motor gets cold enough in order to avoid a burn.
- FANUC motor is designed only the usage for a machine tool. Do not use another
purpose
If a FANUC motor is used for unintended purpose, it may cause an
unexpected accident or trouble. Use a FANUC motor only with
machine tools.
- The base or frame on which the motor is to be mounted must have sufficient
stiffness
Insufficient stiffness or rigidity may cause many troubles. For
example, it generates rough surface in machining, harmful vibration,
abnormal sound, and shorten the life of bearings. It causes also the bad
machining precision of a machine tool itself.
- Install a motor without failure.
It is dangerous that a part of a motor or on the rotating part is removed
or scattered when motor is rotating..
- Connect motor cables correctly.
An incorrect connection of a cable may cause trouble. Use a cable
with thick enough for the current carrying capacity.
- Cool a motor with specified cooling condition.
Insufficient cooling may cause trouble. Keep a specified cooling
condition. Check that the flow rate of liquid is appropriate and the
liquid piping is not clogged. The periodic cleaning and inspection is
necessary. Build the system to stop the motor when the cooling unit is
in trouble.
- Take measures to leakage current.
The leakage current of the synchronous built-in spindle motor may
exceed the value specified in EN60335-1. Take appropriate measures
against leak current. For example, adopting a structure that prevents
the operator from contacting conductive parts near the motor during
power is alive.
- Connect the thermistor line to amplifier
For the thermal protection, connect the thermistor line to the amplifier.
