The machine is equipped with safety devices which serve to protect personnel and the machine itself from
hazards arising from unforeseen accidents. However, operators must not rely exclusively on these safety
devices: they must also become fully familiar with the safety guidelines presented below to ensure accidentfree operation.
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 (3281ft.).
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.
5921-E P-(ii)
SAFETY PRECAUTIONS
3.Precautions Relating to Manual/Continuous Operation
(1) Follow the instruction manual during operation.
(2) Do not operate the machine with the front cover, chuck cover, or another protective cover
removed.
(3) Close the front cover before starting the machine.
(4) When machining the initial workpiece, check for machine operations, run the machine under no
load to check for interference among components, cut the workpiece in the single block mode,
and then start continuous operation.
(5) Ensure your safety before rotating the spindle or moving a machine part.
(6) Do not touch chips or workpiece while the spindle is rotating.
(7) Do not stop a rotating part with hand or another means.
(8) Check that the condition of hydraulic chuck jaws as mounted, operating pressure, and
maximum permissible revolving speed.
(9) Check the condition and location of the cutting tool as mounted.
(10) Check the tool offset value.
(11) Check the zero offset value.
(12) Check that the SPINDLE OVERRIDE and FEEDRATE OVERRIDE dials on the NC operation
panel are set to 100%.
(13) When moving the turret, check the software limits for X- and Z-axes or the locations of limit
switch dogs to prevent interference with the chuck and tailstock.
(14) Check the location of the turret.
(15) Check the location of the tailstock.
(16) Cut workpieces with a transmitted power and torque within the permissible range.
(17) Chuck each workpiece firmly.
(18) Check that the coolant nozzle is properly located.
4.On Finishing Work
(1) On finishing work, clean the vicinity of the machine.
(2) Return the ATC, APC and other equipment to the predetermined retraction position.
(3) Always turn off the power to the machine before leaving it.
(4) To turn off the power, turn off the CONTROL ON switch on the operation panel first, then the
main power disconnect switch.
5921-E P-(iii)
SAFETY PRECAUTIONS
5.Precautions during Maintenance Inspection and When
Trouble Occurs
In order to prevent unforeseen accidents, damage to the machine, etc., it is essential to observe the
following points when performing maitenance inspections or during checking when trouble has
occurred.
(1) When trouble occurs, press the emergency stop button on the operation panel to stop the
machine.
(2) Consult the person responsible for maintenance to determine what corrective measures need
to be taken.
(3) If two or more persons must work together, establish signals so that they can communicate to
confirm safety before proceeding to each new step.
(4) Use only the specified replacement parts and fuses.
(5) Always turn the power off before starting inspection or changing parts.
(6) When parts are removed during inspection or repair work, always replace them as they were
and secure them properly with their screws, etc.
(7) When carrying out inspections in which measuring instruments are used - for example voltage
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.
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?
The motor is normal if there is a strong draft from the unit.
Is the external air inlet blocked?
If it is blocked, clean it with compressed air.
6.General Precautions
(1) Keep the vicinity of the machine clean and tidy.
(2) Wear appropriate clothing while working, and follow the instructions of someone with sufficient
training.
(3) Make sure that your clothes and hair cannot become entangled in the machine. Machine
operators must wear safety equipment such as safety shoes and goggles.
5921-E P-(iv)
SAFETY PRECAUTIONS
(4) Machine operators must read the instruction manual carefully and make sure of the correct
procedure before operating the machine.
(5) Memorize the position of the emergency stop button so that you can press it immediately at any
time and from any position.
(6) Do not access the inside of the control panel, transformer, motor, etc., since they contain high-
voltage terminals and other components which are extremely dangerous.
(7) If two or more persons must work together, establish signals so that they can communicate to
confirm safety before proceeding to each new step.

1-2-1. Alarm Codes
In this manual, alarm codes are explained using such as "X", "XX", and "XXYY".
Explanation is given in the following methods:
(1) The alarm code indicated in this text can be used directly as the key to find the contents of error.
(2) The alarm code indicated in this text should first be converted into bit expression (pattern),
which is then used as the key to find the contents of error.
In the case of 2), the procedure to convert the alarm code into bit pattern is shown below.
The method to find the details of the alarm indicated by the bit pattern is explained below using an
example.
Example:
[Code] XX
XX
bit1->EC I/O power shut off error
bit2->ECC error
bit3->Not used
bit4->Not used
bit5->EDRQ INT signal
bit6->ECP INT signal
bit7->ECP RUN signal
bit0->Battery error
If an alarm occurs, a hexadecimal number is displayed.
If "$C1" is displayed, for example, first convert this "$C1" into bits.
5921-E P-4
SECTION 1 CLASSIFICATION OF ALARMS
After the conversion, it is known that Bit0, Bit6, and Bit7 are ON.
See the information above and you will find that these error codes
correspond to "battery error", "ECP INT signal", and "ECP RUN signal",
respectively.
