A-90188E-01 SAFETY PRECAUTIONS
- 4 -
CAUTION
1 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.
2 The operator's manual for FAST Ethernet / FAST Data
Server describes all the basic functions of the CNC,
including the optional functions. The selected optional
functions vary with the machine. Some functions
described in this manual may not, therefore, be
supported by your machine. Check the machine
specifications before using FAST Ethernet / FAST
Data Server.
3 Some machine operations and screen functions are
implemented by the machine tool builder. For an
explanation of their usage and related notes, refer to
the manual provided by the machine tool builder.
For example:
- On some machines, executing a tool function
causes the tool change unit to operate. When
executing a tool function on such a machine, stand
well clear of the tool change unit. Otherwise, there
is a danger of injury to the operator.
- Many auxiliary functions trigger physical operations,
such as rotation of the spindle. Before attempting to
use an auxiliary function, therefore, ensure that you
are fully aware of the operation to be triggered by
that function.
NOTE
Command programs, parameters, and variables are
stored in nonvolatile memory in the CNC. Generally,
the contents of memory are not lost by a power on/off
operation. However, the contents of memory may be
erased by mistake, or important data in nonvolatile
memory may have to be erased upon recovering from
a failure.
To enable the restoration of data as soon as possible
if such a situation arises, always make a backup of the
data in advance.
