ALARM & ERROR LIST

(4th Edition)

Pub No. 4293-E-R2 (ME37-005-R4) Oct. 2000

4293-E P-(i)

SAFETY PRECAUTIONS

SAFETY PRECAUTIONS

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

(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 excessive 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

(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.

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

(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

(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

(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.

4293-E P-(iii)

SAFETY PRECAUTIONS

6.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 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 permitted to perform any work on these units. Even then, they must observe the following precautions.

•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 temperature 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.

0853 MCS CON APA deviation

Difference between CON and APA values has exceeded the allowable limit. The CON-APC deviation is the absolute value of difference between [calculated value written in MCS] and [actual position read from MCS]. The NC control software monitors this deviation. The MCS normally monitors DIFF value.

This alarm appears if the MCS causes a fatal error and cannot monitor the DIFF value.
