SAFETY PRECAUTIONS
This machine is equipped with safety equipment to protect persons and machinery from any danger that might
happen unexpectedly. However operators are requested to operate the equipment in such a way that no
person will use the equipment in the following unsafe manner and cause an accident without knowing the
following safety precautions.
This instruction manual and the warning signs attached to the machine cover only those hazards which
Okuma can predict.
Be aware that they do not cover all possible hazards.
1. Precautions Relating to Installation
(1) Please be noted about a primary power supply as follows.
Do not draw the primary power supply from a distribution panel that also supplies a major
noise source (for example, an electric welder or electric discharge machine) since this
could cause malfunction of the CNC unit.
If possible, connect the machine to a ground not used by any other equipment. If there is
no choice but to use a common ground, the other equipment must not generate a large
amount of noise (such as an electric welder or electric discharge machine).
(2) Installation Environment
Observe the following points when installing the control enclosure.
Make sure that the CNC unit will not be subject to direct sunlight.
Make sure that the control enclosure will not be splashed with chips, water, or oil.
Make sure that the control enclosure and operation panel are not subject to excessive
vibrations or shock.
The permissible ambient temperature range for the control enclosure is 5 to 40°C (41 to
104°F).
The permissible ambient humidity range for the control enclosure is relative humidity
50% or less at 40°C (104°F) (no condensation).
The maximum altitude at which the control enclosure can be used is 1000 m (3281 ft.).
2. Points to Check before Turning on the Power
(1) Close all the doors of the control enclosure and operation panel to prevent the entry of water,
chips, and dust.
(2) Make absolutely sure that there is nobody near the moving parts of the machine, and that there
are no obstacles around the machine, before starting machine operation.
(3) When turning on the power, turn on the main power disconnect switch first, then the CONTROL
ON switch on the operation panel.
3. Precautions Relating to Operation
(1) After turning on the power, carry out inspection and adjustment in accordance with the daily
inspection procedure described in this instruction manual.
(2) Use tools whose dimensions and type are appropriate for the work undertaken and the machine
specifications. Do not use badly worn tools since they can cause accidents.
(3) Do not, for any reason, touch the spindle or tool while spindle indexing is in progress since the
spindle could rotate: this is dangerous.
(4) Check that the workpiece and tool are properly secured.
(5) Never touch a workpiece or tool while it is rotating: this is extremely dangerous.
(6) Do not remove chips by hand while machining is in progress since this is dangerous. Always
stop the machine first, then remove the chips with a brush or broom.
(7) Do not operate the machine with any of the safety devices removed. Do not operate the
machine with any of the covers removed unless it is necessary to do so.
(8) Always stop the machine before mounting or removing a tool.
5885-E P-(ii)
SAFETY PRECAUTIONS
(9) Do not approach or touch any moving part of the machine while it is operating.
(10) Do not touch any switch or button with wet hands. This is extremely dangerous.
(11) Before using any switch or button on the operation panel, check that it is the one intended.
4. Precautions Relating to the ATC
(1) The tool clamps of the magazine, spindle, etc., are designed for reliability, but it is possible that
a tool could be released and fall in the event of an unforeseen accident, exposing you to danger: do not touch or approach the ATC mechanism during ATC operation.
(2) Always inspect and change tools in the magazine in the manual magazine interrupt mode.
(3) Remove chips adhering to the magazine at appropriate intervals since they can cause
misoperation.
Do not use compressed air to remove these chips since it will only push the chips further in.
(4) If the ATC stops during operation for some reason and it has to be inspected without turning the
power off, do not touch the ATC since it may start moving suddenly.
5. On Finishing Work

checks - make sure the instrument is properly calibrated.
(8) Do not keep combustible materials or metals inside the control enclosure or terminal box.
(9) Check that cables and wires are free of damage: damaged cables and wires will cause current
leakage and electric shocks.
(10) Maintenance inside the Control Enclosure
a. Switch the main power disconnect switch OFF before opening the control enclosure door.
b. Even when the main power disconnect switch is OFF, there may some residual charge in
the MCS drive unit (servo/spindle), and for this reason only service personnel are permitted
to perform any work on this unit. Even then, they must observe the following precautions.
Even then, they must observe the following precautions.
MCS drive unit (servo/spindle)
The residual voltage discharges two minutes after the main switch is turned OFF.
c. The control enclosure contains the NC unit, and the NC unit has a printed circuit board
whose memory stores the machining programs, parameters, etc. In order to ensure that the
contents of this memory will be retained even when the power is switched off, the memory
is supplied with power by a battery. Depending on how the printed circuit boards are
handled, the contents of the memory may be destroyed and for this reason only service
personnel should handle these boards.
(11) Periodic Inspection of the Control Enclosure
a. Cleaning the cooling unit
The cooling unit in the door of the control enclosure serves to prevent excessive
temperature rise inside the control enclosure and increase the reliability of the NC unit.
Inspect the following points every three months.
Is the fan motor inside the cooling unit working?

SECTION 2 METHOD OF OPERATING DNC-T3
(OPTIONAL)
2-1. DNC-T3 Overview
The DNC-T3 offers functions to output the current NC status (operation mode, axis position,
selected program, etc.) through operations or by request from the host personal computer, and to
simply monitor the NC status on the personal computer. It can also output MacMan report
information and trouble information in response to a request from the personal computer. Using
these functions requires an application compatible with the DNC-T3 to be installed in the host
personal computer.
Since the DNC-T3’s functions are operated from the host personal computer, no operations are
required on the NC unit. The DNC-T3 incorporates all the functions of DNC-T1.
The DNC-T3 has the following functions.

DNC-T1
SECTION 2 METHOD OF OPERATING DNC-T3 (OPTIONAL)
2-2. Precautions about DNC-T3 Specifications
To use the DNC-T3’s functions, a compatible application such as MacMan-Net must be installed in
the personal computer (compatible only with Windows NT/2000/XP Professional but not compatible
with UNIX systems).
When collecting the MacMan report information or trouble information through operations from the
personal computer, make appropriate MacMan environment settings for the personal computer
(such as I/O device names, pathname, and file name).
If you try to use any of the DNC-T1 functions from the NC while the personal computer is monitoring
the NC, the NC may fail to connect with the personal computer depending on the timing.
In that case, retry the same operation.
The NC cannot be output the machining management data such as environment settings, report
information or trouble information while it is collecting such information on receiving commands from
the personal computer. If data output is attempted, the following message appears: “Cannot execute
during communication with host” A message appears to ask if you really want to delete it.
In that case, ensure that the NC is not collecting machining management data before outputting the
data.
If the collection of report information or trouble information initiated by the personal computer is
forced to terminate also by the personal computer, the following error occurs:
“ALARM D 4056 DNC-T error”
To clear this alarm, press the NC RESET key.
