SAFETY PRECAUTIONS
Eeoemalpl001
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 accident-free 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 Machine Installation
Eeoemalpl002
(1) Install the machine at a site where the following conditions (the conditions for achievement of
the guaranteed accuracy) apply.
•
Ambient Temperature: 17 to 25
°
C
•
Ambient humidity: 75% max. (no condensation)
•
Site not subject to direct sunlight or excessive vibration; environment as free of dust, acid,
corrosive gases, and salt spray as possible.
(2) Prepare a primary power supply that complies with the following requirements.
•
Voltage: 200V
• Voltage fluctuation: ±10% max.
•
Power supply frequency: 50/60 Hz
•
Do not draw the primary power supply from 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 NC 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).
(3) Installation Environment
Observe the following points when installing the electrical control cabinet.
•
Make sure that the NC unit will not be subject to direct sunlight.
• Make sure that the electrical control cabinet will not be splashed with chips, water, or oil.
•
Make sure that the electrical control cabinet and operation panel are not subject to exces-
sive vibrations or shock.
•
The permissible ambient temperature range for the electrical control cabinet is 0 to 40
°
C.
•
The permissible ambient humidity range for the electrical control cabinet is 30 to 95% (no
condensation).
•
The maximum altitude at which the electrical control cabinet can be used is 1000 m (3281
ft.).
2. Points To Check Before Turning On The Power
Eeoemalpl003
(1) Close all the doors of the electrical control cabinet 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.
Page 3
4293-E P-(ii)
SAFETY PRECAUTIONS
(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
Eeoemalpl004
(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.
(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
Eeoemalpl005
(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 dan-
ger: 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 misoper-
ation. 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
Eeoemalpl006
(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.

SAFETY PRECAUTIONS
6. Precautions During Maintenance Inspection and When
Trouble Occurs
Eeoemalpl007
In order to prevent unforeseen accidents, damage to the machine, etc., it is essential to observe the
following points when performing maintenance 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 electrical control cabinet 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 Electrical Control Cabinet
a) Switch the main power disconnect switch OFF before opening the electrical control cabinet
door.
b) Even when the main power disconnect switch is OFF, there may some residual charge in
the servo amplifier and spindle drive unit, and for this reason only service personnel are per-
mitted to perform any work on these units. Even then, they must observe the following pre-
cautions.
•
Servo amplifier
•
Discharge the residual voltage one minute after turning off the breaker inside the unit.
•
Spindle drive unit
•
Discharge the residual voltage one minute after turning off the main power disconnect
switch.
c) The electrical control cabinet 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 Electrical Control Cabinet
a) Cleaning the cooling unit
The cooling unit in the door of the electrical control cabinet serves to prevent excessive tem-
perature rise inside the electrical control cabinet 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.
Page 5
4293-E P-(iv)
SAFETY PRECAUTIONS
•
Is the external air inlet blocked?
If it is blocked, clean it with compressed air.
7. General Precautions
Eeoemalpl008
(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 oper-
ators must wear safety equipment such as safety shoes and safety goggles.
(4) Machine operators must read the instruction manual carefully and make sure of the correct pro-
cedure 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.

0905 SVP APA pattern data
Eeoemale2076
The SVP has successively detected wrong patters of positional data sent from the position encoder.
Ex.)Displayed code: 8000
Conversion into the octal number
8000 (hexadecimal number) -> 100000 (octal number)
Since the E8 unit reads up to 5 digits and ignores the sixth digit, all the digits become 0, causing the OSP to judge that no data is
output from the encoder.

0906 SVP APA speed
Eeoemale2077
The position encoder value (RAPA) changes according to the motor speed. The NC checks the variation of position encoder val-
ues at regular intervals. If the feedrate of each axis is abnormally high compared with the normal rapid traverse rate, or the value
changes in abnormal manner due to malfunction of the position encoder, the variation per unit time exceeds a fixed allowable
limit, causing this alarm.

Eeoemale2078
When the axis is in the target position or at a standstill, the target value, operation value, and actual position data are the same.
With designation of an axis moving command, the NC starts calculating the path to the target position, thus creating operation
values (RCON). The NC then monitors the variation of the operation values at regular intervals. If the value changes in abnormal
manner for some reason exceeding the allowable limit, this alarm occurs.

Eeoemale2079
When the axis is in the target position or at a standstill, the target value, operation value, and actual position data are the same.
With designation of an axis moving command, the NC starts calculating the path to the target position, thus creating operation
values (RCON). This time, the actual position data follows the operation values with a certain delay. This delay amount obtained
by subtracting [actual position] from [operation value] is termed following error. If the following error exceeds the allowable limit,

ZZZZ:Two high-order bytes of the SVP system address in trouble
X=2->Time out
The SVP does not send any response within 20 seconds at the time of start up. Minute investigation should be made to
locate the cause.
Since the SVP cannot detect the start up signal, it cannot execute the start up sequence.

1002 SVP CON APA deviation
Eeoemale3003
Deviation between CON and APA has exceeded the preset limit.
The deviation can be obtained by the formula: [Calculated value written in SVP]
- [Actual position read from SVP].
This value is monitored by the control software such as that for NC.
The SVP usually monitors DIFF. However, when the SVP becomes unable to monitor DIFF due to fatal abnormality, this monitor-
ing function will prevent the system overrun.

1005 SVP APA pattern data
Eeoemale3006
The SVP has successively detected wrong patterns of positional data sent from the position encoder.
Ex. Displayed code: 8000
Conversion into the octal number
8000(hexadecimal number)->100000 (octal number) Since the E8 unit reads up to 5 digits and ignores the sixth digit, all the digits
become 0, causing the OSP to judge that no data is output from the encoder.

• SVP hardware of the problem axis
• Timing signal from the NC unit
1006 SVP APA speed
Eeoemale3007
The position encoder value (RAPA) changes according to the motor speed. The NC checks the variation of position encoder val-
ues at regular intervals. If the feedrate of each axis is abnormally high compared with the normal rapid traverse rate, or the value
changes in abnormal manner due to malfunction of the position encoder, the variation per unit time exceeds a fixed allowable
limit, causing this alarm.

However, the following codes represents special meanings.
FFFFFFFF->The variation has exceeded the liner axis stroke.
FFFFFFFE->The variation has exceeded the rotary axis stroke (360-deg), or the positional data of the infinite axis has
changed to a negative value.
FFFFFFFD->The variation has exceeded the infinite axis stroke.

When the axis is in the target position or at a standstill, the target value, operation value, and actual position data are the same.
With designation of an axis moving command, the NC starts calculating the path to the target position, thus creating operation
