SAFETY PRECAUTIONS
s–4
WARNING
6. Immediately after switching on the power, do not touch
any of the keys on the MDI panel until the position display
or alarm screen appears on the CNC unit.
Some of the keys on the MDI panel are dedicated to
maintenance or other special operations. Pressing any
of these keys may place the CNC unit in other than its
normal state. Starting the machine in this state may
cause it to behave unexpectedly.
7. The this Handbook and other manuals supplied with a
CNC unit provide an overall description of the machine’s
functions, including any optional functions. Note that the
optional functions will vary from one machine model to
another. Therefore, some functions described in the
manuals may not actually be available for a particular
model. Check the specification of the machine if in doubt.
8. Some functions may have been implemented at the
request of the machine–tool builder. When using such
functions, refer to the manual supplied by the
machine–tool builder for details of their use and any
related cautions.
NOTE
Programs, parameters, and macro variables are stored in
nonvolatile memory in the CNC unit. Usually, they are retained
even if the power is turned off. Such data may be deleted
inadvertently, however, or it may prove necessary to delete all
data from nonvolatile memory as part of error recovery.
To guard against the occurrence of the above, and assure
quick restoration of deleted data, backup all vital data, and
keep the backup copy in a safe place.
