SAFETY PRECAUTION B-63404EN/03
s-4
WARNING
5 The parameters for the CNC and PMC are factory-
set. Usually, there is no need to change them.
When, however, there is no alternative other than to
change a parameter, ensure that you fully Failure to
set a parameter correctly may result in the machine
behaving unexpectedly, possibly causing damage to
the workpiece and/or machine itself, or injury to the
user.
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 DeviceNet board
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 DeviceNet
board.
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.
