WARNINGS RELATED TO CHECK OPERATION

WARNING

When checking the operation of the machine with the cover removed (1) The user’s clothing could become caught in the spindle or other components, thus

presenting a danger of injury . When checking the operation, stand away from the machine to ensure that your clothing does not become tangled in the spindle or other components.

(2) When checking the operation, perform idle operation without workpiece. When a

workpiece is mounted in the machine, a malfunction could cause the workpiece to be dropped or destroy the tool tip, possibly scattering fragments throughout the area. This presents a serious danger of injury . Therefore, stand in a safe location when checking the operation.

When checking the machine operation with the power magnetics cabinet door opened (1) The power magnetics cabinet has a high–voltage section (carrying a

mark). Never touch the high–voltage section. The high–voltage section presents a severe risk of electric shock. Before starting any check of the operation, confirm that the cover is mounted on the high–voltage section. When the high–voltage section itself must be checked, note that touching a terminal presents a severe danger of electric shock.

(2) Within the power magnetics cabinet, internal units present potentially injurious corners and

projections. Be careful when working inside the power magnetics cabinet.

Never attempt to machine a workpiece without first checking the operation of the machine. Before starting a production run, ensure that the machine is operating correctly by performing a trial run using, for example, the single block, feedrate override, or machine lock function or by operating the machine with neither a tool nor workpiece mounted. Failure to confirm the correct operation of the machine may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user.

Before operating the machine, thoroughly check the entered data. Operating the machine with incorrectly specified data may result in the machine behaving unexpectedly , possibly causing damage to the workpiece and/or machine itself, or injury to the user.

W ARNING

Ensure that the specified feedrate is appropriate for the intended operation. Generally , for each machine, there is a maximum allowable feedrate. The appropriate feedrate varies with the intended operation. Refer to the manual provided with the machine to determine the maximum allowable feedrate. If a machine is run at other than the correct speed, it may behave unexpectedly , possibly causing damage to the workpiece and/or machine itself, or injury to the user.

When using a tool compensation function, thoroughly check the direction and amount of compensation. Operating the machine with incorrectly specified data may result in the machine behaving unexpectedly , possibly causing damage to the workpiece and/or machine itself, or injury to the user.

WARNINGS RELATED TO REPLACEMENT

WARNING

Always turn off the power to the CNC and the main power to the power magnetics cabinet. If only the power to the CNC is turned off, power may continue to be supplied to the serve section. In such a case, replacing a unit may damage the unit, while also presenting a danger of electric shock.

When a heavy unit is to be replaced, the task must be undertaken by two persons or more. If the replacement is attempted by only one person, the replacement unit could slip and fall, possibly causing injury.

After the power is turned off, the servo amplifier and spindle amplifier may retain voltages for a while, such that there is a danger of electric shock even while the amplifier is turned off. Allow at least twenty minutes after turning off the power for these residual voltages to dissipate.

When replacing a unit, ensure that the new unit has the same parameter and other settings as the old unit. (For details, refer to the manual provided with the machine.) Otherwise, unpredictable machine movement could damage the workpiece or the machine itself, and present a danger of injury .

WARNINGS RELATED TO PARAMETERS

WARNING

When machining a workpiece for the first time after modifying a parameter, close the machine cover. Never use the automatic operation function immediately after such a modification. Instead, confirm normal machine operation by using functions such as the single block function, feedrate override function, and machine lock function, or by operating the machine without mounting a tool and workpiece. If the machine is used before confirming that it operates normally , the machine may move unpredictably , possibly damaging the machine or workpiece, and presenting a risk of injury.

The CNC and PMC parameters are set to their optimal values, so that those parameters usually need not be modified. When a parameter must be modified for some reason, ensure that you fully understand the function of that parameter before attempting to modify it. If a parameter is set incorrectly, the machine may move unpredictably, possibly damaging the machine or workpiece, and presenting a risk of injury.

WARNINGS AND NOTES RELATED TO DAILY MAINTENANCE

WARNING

Memory backup battery replacement

When replacing the memory backup batteries, keep the power to the machine (CNC) turned on, and apply an emergency stop to the machine. If this work is performed with the power on and the cabinet open, only those personnel who have received approved safety and maintenance training may perform this work. When replacing the batteries, be careful not to touch the high–voltage circuits (marked

and fitted with an insulating cover). Touching the uncovered high–voltage circuits presents an extremely dangerous electric shock hazard.

NOTE

The CNC uses batteries to preserve the contents of its memory , because it must retain data such as programs, offsets, and parameters even while external power is not applied. If the battery voltage drops, a low battery voltage alarm is displayed on the machine operator’s panel or CRT screen. When a low battery voltage alarm is displayed, replace the batteries within a week. Otherwise, the contents of the CNC’s memory will be lost. To replace the battery, see the procedure described in Section 2.8 of this manual.

Absolute pulse coder battery replacement

and fitted with an insulating cover). Touching the uncovered high–voltage circuits presents an extremely dangerous electric shock hazard.

NOTE

The absolute pulse coder uses batteries to preserve its absolute position. If the battery voltage drops, a low battery voltage alarm is displayed on the machine operator’s panel or CRT screen. When a low battery voltage alarm is displayed, replace the batteries within a week. Otherwise, the absolute position data held by the pulse coder will be lost. To replace the battery, see the procedure described in Section 2.8 of this manual.

The complete connection diagram shows examples of connecting all PC boards that can fit into the slots of the master PC board. Some slots can accept two or more PC boards which are connected to different devices. This drawing shows two or more identical slot names, but actual individual slots on the master PC board have different names. See the connection of each slot according to the PC board to be fitted into the slot.

The diagram shows the connection of all PC boards that can be fitted into the slots. In the actual unit, the PC boards to be mounted are determined by the model and optional functions. Note that all the PC boards shown in the diagram are not always mounted.

Similarly to the pulse coder, the manual pulse generator is designed to operate on 5 VDC. So, any voltage drop relative to the supply voltage must be kept to within 0.2 V (total drop through the 0 V and 5 V lines). Namely:

0.2 y

0.1 R 2L

where 0.1 : Current required by the manual pulse generator

R : Wire resistance per unit length [Ω/m] m : Number of wires in the 0 V or 5 V cable L : Cable length [m]

Thus,

RECOMMENDED CABLE MATERIAL A66L–0001–0284#10P(#28WAG 10 pair) RECOMMENDED CABLE SPECIFICATION A02B–0120–K800(5m)

NOTE

1 The total length of the cable between the CNC and amplifier and that between the amplifier and

motor shall not exceed 50m.

2 As the current feedback lines (IRn and ISn), use the middle twisted pair of the recommended

cable. If any other pair is used, abnormal noise or oscillation may occur.

3 Use a servo unit which supports the type–B interface. When using a servo unit which supports

both the type–A and type–B interfaces, select the type–B interface. For details, refer to the manual supplied with the servo unit. If the interface setting is incorrect, a servo alarm (AL401 V READY OFF) will be issued.

(2) Internal type pulse coder (Serial pulse coder interface)

The connector to which the feedback cable from the built–in pulse coder is connected varies with the servo interface type.

For the type A interface, connect the feedback cable to the feedback connector on the axis control card (for example, M185 for the first axis).

For the type B interface, connect the feedback cable to the feedback connector on the servo amplifier (for example, JF1 for the first axis).

(5) Handling of unused axes (Clamping)

The user can select any of the supported axes as the axes to be controlled. A cable for a servo amplifier or motor need not be connected to those axes that are not to be used. Leaving the connector for an unused axis open, however, causes the CNC to enter a servo alarm state. This section describes how to handle (clamp) unused axes.

NOTE

Servo parameters must also be set for clamped axes. Set the same servo parameters as those for any axis to be used.

The CNC has been steadily reduced in size using surface–mount and custom LSI technologies for electronic components. The CNC also is designed to be protected from external noise. However, it is difficult to measure the level and frequency of noise quantitatively, and noise has many uncertain factors. Generally, noise is induced in the CNC due to electrostatic coupling, electromagnetic induction, and ground loop. The CNC is equipped with provisions to minimize the influence of extraneous noise. However, it is difficult to quantitatively measure the strength of the noise and how often it occurs. Besides, noise has many unknown elements. To maintain the stability of the CNC machine tool system, it is important to minimize the occurrence of noise and prevent it from being induced into the CNC. When designing the power magnetics cabinet, guard against noise in the machine as described in the following section.

(1) Separationg signal lines

The cables used for the CNC machine tool are classified as listed in the following table: Process the cables in each group as described in the action column.

to safely carry the accidental current flow into the system ground when an accident such as a short circuit occurs. (Generally, it must have the cross–sectional area of the AC power cable or more.)

D Use the cable containing the AC power wire and the system

ground wire so that power is supplied with the ground wire connected.

(3) Noise suppressor

The AC/DC solenoid and relay are used in the power magnetics cabinet. A high pulse voltage is caused by coil inductance when these devices are turned on or off. This pulse voltage induced through the cable causes the electronic circuits to be disturbed.

D Use a spark killer consisting of a resistor and capacitor in series. This

type of spark killer is called a CR spark killer.(Use it under AC) (A varistor is useful in clamping the peak voltage of the pulse voltage, but cannot suppress the sudden rise of the pulse voltage. FANUC therefore recommends a CR spark killer.)

D The reference capacitance and resistance of the spark killer shall

conform to the following based on the current (I (A)) and DC resistance of the stationary coil:

1) Resistance (R) : Equivalent DC resistance of the coil

2) Capacitance (C) :

(mF)

I : Current at stationary state of the coil

NOTE

Use a CR–type noise eliminator. Varistor–type noise eliminators clamp the peak pulse voltage but cannot suppress a sharp rising edge.

Use a diode which can withstand a voltage up to two times the applied voltage and a current up to two times the applied current.

B–62545EN/02

Part programs, offset data, and system parameters are stored in the CMOS memory of the control unit. Three ”D”(R20) size alkaline batteries are used to back up the memory of the control unit when the AC power source is off. These batteries are held in the battery unit. The user is requested to replace these batteries once a year. When replacing the batteries, it is necessary to keep the power supply switched on. Note that if the batteries are removed when the power supply is off, the contents (parameters and programs) of memory will be lost.

If the battery voltage drops, the warning message ”BAT” appears on the CRT screen, and a battery alarm signal is sent to the PMC. If a battery alarm occurs, replace the batteries as soon as possible (no later than within one or two weeks). Actually, however, the battery life depends on the configuration of your system.

If the battery voltage drops even further, it will become impossible to provide memory backup. If the power is switched on under this condition, a system alarm (SRAM party alarm) occurs, because the contents of memory will have been damaged. Therefore, after replacing the batteries, it is necessary to clear the entire contents of memory and re–enter the necessary programs and data. Keep the power switched on when replacing the batteries. Do not forget that disconnecting the memory backup batteries with the power switched off will result in the total loss of the memory contents.

Battery replacement method

1 Obtain three new ”D” (R20) size alkaline dry cells. 2 Switch on the power to the control unit. 3 Remove the battery case lid. 4 Replace the batteries, observing the correct orientation. 5 Replace the battery case lid. 6 Switch off the power to the control unit.

It is easy to mount and dismount the CNC power supply unit, because it is designed to be mounted on, and connected directly to, the master printed–circuit board. All its AC inputs and DC outputs are linked via connectors.

Because this power supply unit has a built–in input unit function, it is not necessary to prepare a separate relay or input unit for switching the AC input on and off. The AC input can be connected directly to the power supply unit. The unit has an AC service outlet, which is switched on and off simultaneously with the power supply unit. This AC service outlet can be used to supply power to a unit such as a fan motor.

(3) Adjustments and settings

This power supply unit requires no adjustment or setting. Do not attempt to adjust the reference voltage (=10.00V) at A10 unless absolutely necessary , because the reference voltage has been adjusted during unit test; merely confirm the voltage across A10 and A0 of check connector CP16. If the reference voltage at A10 falls outside the rated range, set it to

10.00V, using VR11, while measuring the voltage with a digital

voltmeter. Rotating VR11 clockwise increases the voltage at A10. After the power supply unit is replaced, always to check the reference voltage at A10.

(4) Causes of blown fuses and required corrective actions

This power supply unit is provided with fuses F11 and F12 at its input, fuse F13 at the +24 V output, and fuse F14 at the +24E output. Possible causes of these fuses blowing are listed below together with the corrective actions required to restore normal operation.

1. Fuses F11 and F12 (a) Short circuit in surge absorber VS11

VS11 is intended to suppress surge voltages on the input line. If an excessively large surge voltage or steady voltage is applied to VS11, it breaks down, short–circuiting and, causing F11 and F12 to blow. If VS11 has short–circuited, but you do not have a replacement part on hand, the machine can be used with VS11 removed. In such a case, however, you should obtain a replacement and install it as soon as possible, especially when the machine is being used in an installation prone to surge voltages. The specification

number of VS11 is A50L–8001–0067#431U. (b) Short circuit in diode stack DS11 (c) Short circuit between the collector and emitter of switching

transistors Q14 and Q15 (d) Short circuit in diodes D33 and D34 (e) Short circuit between the collector and emitter of transistor

Q1 in the auxiliary power supply circuit If you suspect that any of short circuits (b) to (e) has occurred in

the respective parts, replace the power supply unit with a spare. When replacing a fuse, use a replacement having the same rating. The specification number for fuses F11 and 12 is A60L–0001–0245#GP75.

2. Fuse F13 (a) A short circuit may have occurred in the CRT/MDI unit or a

+24 V power supply cord leading to it. Remove the cord from CP15, and check the unit and cord carefully.

(b) A short circuit may have occurred in the +24 V circuit on the

master printed–circuit board. Remove the cable from CP14 and CP15. Also, remove the power supply unit from the master printed–circuit board, then check the printed–circuit board carefully. When replacing a fuse, use a replacement having the same rating. The specification number for fuse F13 is A60L–0001–0075#3.2.

3. Fuse F14 (a) Short circuit in +24E power supply cables for various

printed–circuit board units

(b) Ground fault of the +24E power supply line in the machine

or false contact of the +24E power supply line with another power supply line

If either of (a) or (b) may have occurred, remove the cable from CP14, and check it carefully. When replacing a fuse, use a replacement part having the same rating. The specification number for fuse F14 is A60L–0001–0046#5.0.

2. HARDWARE

B–62545EN/02

4. Fuse F1 Fuse F1 and surge absorber VS1 are wired so that, if a high current

flows through VS1, it may cause F1 to blow . This is intended to protect the circuits in the power supply unit from an abnormal voltage that may occur due to a failure in the auxiliary power supply circuit of the power supply unit and an abnormal voltage that may originate in the power supply ON/OFF switch contact signal line or external alarm signal line. If F1 blows, probable causes are:

(1) Failure in the auxiliary power supply circuit (M1, Q1, T1,

D1, Q2, or ZD1)

(2) False contact between the power supply ON/OFF switch

contact signal line or external alarm signal line and the AC power line

If cause (1) is more likely , replace the power supply unit. If cause (2) is more likely, replace the power supply unit, because the power supply unit may have failed. After the power supply ON/OFF switch contact signal line and external alarm signal line have been checked, and all abnormal conditions (if any) have been cleared, if replacing F1 restores normal operation, there is no need to replace the power supply unit. The specification number of fuse F1 is A60L–0001–0172#DM03. When replacing the fuse, use a replacement having the same rating.

It is necessary to regulary clean the heat transformer, because the heat transformation ability will be reduced by the accumulation of dust. The frequency of the cleaning needed differs according to the installation environment and therefore should be determined by your own judgment according to the degree of dirt.

Air filter cleaning and replacement method

1 When cleaning and replacing the filter, be sure to cut off the fan’s

electric power source.

2 Detach the filter cover and take out the filter inside.

Detach the cover by pressing, the flanges which are in the grooves of both sides towards the inside by minus screwdriver, etc.

3 Protect the filter from silting due to dust by blowing air on both sides.

4 When dirt is conspicuous, press wash with a neutral detergent, rinse

with fresh water, and the washing, allow to dry naturally. When replacing with the same product.

5 Insert the filter in the cover, align the flange in the groove, and install

by pressing. Confirm that the cover will not come loose even if it is pulled.
