CAUTION

All teaching work must be carried out by an operator who has received special training. (This also applies to maintenance work with the power source turned

ON.)

Enforcement of safety training

For teaching work, prepare a work plan related to the methods and procedures of operating the robot, and to the measures to be taken when an error occurs or when restarting. Carry out work following this plan. (This also applies to maintenance work with the power source turned ON.)

Preparation of work plan

Prepare a device that allows operation to be stopped immediately during teaching work. (This also applies to maintenance work with the power source turned ON.)

Setting of emergency stop switch

During teaching work, place a sign indicating that teaching work is in progress on the start switch, etc. (This also applies to maintenance work with the power source turned ON.)

Indication of teaching work in progress

Provide a fence or enclosure during operation to prevent contact of the operator and robot.

Installation of safety fence

Establish a set signaling method to the related operators for starting work, and follow this method.

Signaling of operation start

As a principle turn the power OFF during maintenance work. Place a sign indicating that maintenance work is in progress on the start switch, etc.

Indication of maintenance work in progress

Before starting work, inspect the robot, emergency stop switch and other related devices, etc., and confirm that there are no errors.

Inspection before starting work

Refer to the actual "Safety Manual" for details.

CAUTION

Use the robot within the environment given in the specifications. Failure to do so could lead to a drop or reliability or faults. (Temperature, humidity, atmosphere, noise environment, etc.)

CAUTION

Transport the robot with the designated transportation posture. Transporting the robot in a non-designated posture could lead to personal injuries or faults from dropping.

CAUTION

Always use the robot installed on a secure table. Use in an instable posture could lead to positional deviation and vibration.

CAUTION

Wire the cable as far away from noise sources as possible. If placed near a noise source, positional deviation or malfunction could occur.

CAUTION

Do not apply excessive force on the connector or excessively bend the cable.

Failure to observe this could lead to contact defects or wire breakage.

CAUTION

Make sure that the workpiece weight, including the hand, does not exceed the rated load or tolerable torque. Exceeding these values could lead to alarms or faults.

WARNING

Securely install the hand and tool, and securely grasp the workpiece. Failure to observe this could lead to personal injuries or damage if the object comes off or flies off during operation.

WARNING

Securely ground the robot and controller. Failure to observe this could lead to malfunctioning by noise or to electric shock accidents.

CAUTION

Indicate the operation state during robot operation. Failure to indicate the state could lead to operators approaching the robot or to incorrect operation.

WARNING

When carrying out teaching work in the robot's movement range, always secure the priority right for the robot control. Failure to observe this could lead to personal injuries or damage if the robot is started with external commands.

CAUTION

Keep the jog speed as low as possible, and always watch the robot. Failure to do so could lead to interference with the workpiece or peripheral devices.

CAUTION

After editing the program, always confirm the operation with step operation before starting automatic operation. Failure to do so could lead to interference with peripheral devices because of programming mistakes, etc.

CAUTION

Make sure that if the safety fence entrance door is opened during automatic operation, the door is locked or that the robot will automatically stop. Failure to do so could lead to personal injuries.

CAUTION

Never carry out modifications based on personal judgments, or use nondesignated maintenance parts.

Failure to observe this could lead to faults or failures.

WARNING

When the robot arm has to be moved by hand from an external area, do not place hands or fingers in the openings. Failure to observe this could lead to hands or fingers catching depending on the posture.

CAUTION

CAUTION

CAUTION

Do not stop the robot or apply emergency stop by turning the robot controller's main power OFF. If the robot controller main power is turned OFF during automatic operation, the robot accuracy could be adversely affected. Moreover, it may interfere with the peripheral device by drop or move by inertia of the arm.

Do not turn off the main power to the robot controller while rewriting the internal information of the robot controller such as the program or parameters.

If the main power to the robot controller is turned off while in automatic operation or rewriting the program or parameters, the internal information of the robot controller may be damaged.

Use the network equipments (personal computer, USB hub, LAN hub, etc) confirmed by manufacturer. The thing unsuitable for the FA environment

(related with conformity, temperature or noise) exists in the equipments connected to USB. When using network equipment, measures against the noise, such as measures against EMI and the addition of the ferrite core, may be necessary. Please fully confirm the operation by customer. Guarantee and maintenance of the equipment on the market (usual office automation equipment) cannot be performed.

*CR751-D or CR751-Q controller

Notes of the basic component are shown.

CAUTION

Please install the earth leakage breaker in the primary side supply power supply of the controller of CR751-D or CR751-Q because of leakage protection.

CAUTION

Be careful of interference with peripheral equipment.

Especially don't give a shock to the shaft (J3 axis). When you install the hand, be careful not to knock at the shaft end by the hammer etc. The shaft may be damaged.

Take care also of the following items.

(1)The robot's locus of movement may change with specified speed.

Especially as for the corner section, short cut distance may change. Therefore, when beginning automatic operation, moves at low speed at first, and you should gather speed slowly with being careful of interference with peripheral equipment.

Short cut

Arch movement (example)

(2)It can be confirmed whether the specified position exist in the defined area by using the instruction command "Zone". It can utilize as one of the methods for collision evasion. Refer to the

"detailed description of the instructions manual/function, and operation" of the separate volume for the details of the instruction command.

2.4 Confirming the operation

In this section, the robot will be moved manually using the T/B to confirm that the operation is correct.

Moving the robot manually is called "jog operation". This operation includes the JOINT jog that moves each axis, the XYZ jog that moves along the base coordinate system, the TOOL jog that moves along the tool coordinate system, and the CYLNDER jog that moves along the circular arc.

This operation is carried out while pressing the deadman switch on the back of the T/B.

Note) The figure of the robot which indicated to the explanation page in each jog mode is an example.

CAUTION

The robot will move during this operation. Make sure that there are no operators near the robot, and that there are no obstacles, such as tools, in the robot operation range.

CAUTION

To immediately stop the robot, release the deadman switch on the back of the T/B.

The servo power will turn OFF, and the robot will stop.

The robot will also stop if the [EMG.STOP] switch (emergency stop switch) on the front of the T/B or the [EMG.STOP] switch (emergency stop) on the front of the controller is pressed.

WARNING

Confirm that the origin has been set. If the origin has not been set, "****" will appear at the current position display on the teaching pendant, the JOINT jog oper

ation will take place in any jog mode selected.

Refer to

Page 22, "2.3 Setting the origin" for details on setting the origin.

By this jog operation, robot can be move along with the direction of work (or working table etc.), so teaching operations get easier.

When jog operation, select by which work coordinates the robot moves

The setting method of the work coordinates system using T/B (R32TB) is shown in the following.

(Parameter: Setting the coordinate value to WKnCORD ("n" is meaning the number (1-8) of work coordinates) can also set up the work coordinates system. Refer to the separate manual "Detailed

Explanation of Functions and Operations" for details of parameter.)

The work coordinates system teaches and sets up the three points (WO, WX, WY).

(1) Packing Replacement Instructions

Stick again new packing as before.

1) Remove the old packing, and clean and degrease the surface on which it has been placed.

2) The sticking surface of packing is double-coated adhesive tape. Referring to

"Fig.5-5 : Example of sticking packing (good example)"

and

"Fig.5-7 : Sticking the cord-like packing"

, and stick the packing in line with form . Be careful for the packing not to slide. The example of unsuitable packing slid is shown in

"Fig.5-

6 : Example of sticking packing (bad example)"

.

3) Although the No.2 arm cover (U) sticks two or more packings per place, it has length with which packing

ends overlap. Stick packing in the following procedures. For more information, see "Fig.5-8 : Examples of packing overlaps".

Examples of improperly treated cut edge are shown, as well.

a) Stick packing in line with form of the sticking surface. Finally, cut packing so that adjoining pieces have a 1mm overlap at the end.

b) Apply liquid gasket to the cut edges. (Designated liquid gasket: 1212 (Maker: Three Bond)) c) Stick so that the gap may not be made to each other's packing.

CAUTION

Do not install the cover immediately after sticking packing. Install the cover, after the 6 hours pass after sticking packing for gasket hardening.

4) Confirm that packing is stuck correctly and install the cover. When tightening the bolts fixing the cover, avoid tightening them to a specified torque at a time. Tighten the bolt in the order shown as much as possible in the "Fig. 5-10: Example of order which tighten bolts." The torque which tightens the fixing bolt

of each cover is shown in "Table 5-3 : Cover fixing screw list" .

CAUTION

Stick the packing securely, pressing down with the finger. If sticking is insuffi

cient, when the cover is installed, packing slides by the pressure, and there is a possibility that it may become impossible to secure protection performance.

5.3.4 Inspection, maintenance and replacement of timing belt

This robot uses a timing belt for the drive conveyance system of the J5 axis. Compared to gears and chains, the timing belt does not require lubrication and has a low noise. However, if the belt usage method and tension adjust

ment are inadequate, the life could drop and noise could be generated. Sufficient aging to remove the initial elon

gation of the belt, and adjustment of the belt tension have been carried out before shipment from the factory.

However, depending on the robot working conditions, elongation will occur gradually over a long time. The tension must be confirmed during the periodic inspection.

The replacement is necessary if the timing belt is in the condition which showed in "(1)Timing belt replacement period"

. The inspection and adjustment and replacement method of the timing belt of each axis is shown below.

Please check, and adjust and replace if necessary.

In addition, it is serviceable if there is the sound wave type belt tension gauge in inspection and adjustment of the

timing belt. The recommendation gauge is shown below. Please prepare by customer. Refer to the Page 84, "(7)

Timing belt tension"

for the tension adjustment value of the timing belt.

Maker:Gates Unitta Asia Company,

Type:U-505

Image of Measurement by the sound wave type belt tension gauge

Fig.5-10 : Tension adjustment method of timing belt

Measurement by the push-pull gauge

(1) Timing belt replacement period

The timing belt life is greatly affected by the robot working conditions, so a set time cannot be given. However, if the following symptoms occur, replace the belt.

1) When cracks from at the base or back of the belt teeth.

2) When the belt expands due to adherence of oil, etc.

3) When the belt teeth wear (to approx. half of the tooth width).

4) When the belt teeth jump due to belt teeth wear.

5) When the belt snaps.

CAUTION

Due to the manufacturing of the timing belt, initial wear will occur. Wear chips may accumulate in the cover after approx. 300 Hr of operating the robot, but this is not a fault. If the wear chips appear soon after wiping them off, replace the belt.

CAUTION

When the belt is replaced, the machine system origin may deviate. In this case, the position data must be reviewed.

Note) The value given in the table is the value of proper tension. Because the tension declines by the infancy expansion when exchanged to new belt, please adjust proper tension again after the operation for the about 100 hours when exchanged to new belt

The timing belt can satisfactorily convey the drive and keep a durable force only when it has an adequate tension.

The belt tension should not be too tight or too loose. Instead, it should be adjusted to a degree that elasticity is felt when the belt is pressed with the thumb. If the belt tension is too weak, the belt loosening side will vibrate. On the other hand, if the belt tension is too strong, a sharp sound will be heard and the belt tension side will vibrate.

The detailed adjustment (tension) is shown in Fig. 5-14

.

Check and adjust with the belt pressing force f and the slack amount d between spans.

[Caution]

・ The brand name of the grease shown in the Table 5-7

is the grease put in at shipping.

・The lubrication time is a cumulative value of the operation at the maximum speed. If the operation has been sus

pended, or if the designated speed is slow, the lubrication time can be lengthened in proportion.

・ Depending on the robot operation state, the lubrication time will fluctuate, so determine the time according to the state so that the grease does not run out.

・ By the maintenance forecast function of RT ToolBox2 (option) computes the guide of the lubrication hours put together with the customer's operation status.

・ The numbers in the Table 5-7 correspond to the supply positions in Fig. 5-17

.

・Because excessive lubrication leads to the grease leak, avoid it. And, the number of times of lubrication limits to

3 times. The maintenance after it needs the overhaul work which replaces internal grease. Please ask dealer.

(2) Lubrication method to the J1, J2, axis

1) Turn off the controller's power supply.

2) Refer to the "Fig.5-6 : Installing/removing the cover" and remove the covers.

3) Insert the grease shown in

Table 5-7 using a grease gun from the lubrication grease nipple. Add only the

specified amount of grease. Adding excess grease may cause grease to leak.

CAUTION

Use manual grease gun, and inject grease with pressure 0.03Mpa or less. Do not use the grease gun, which derived by the factory air presser to avoid injecting by too high pressure.

Recommendation grease gun: KH35 (Yamada Corporation Inc.,)

4) Install the removed cover as before.

Note) Sealant is applied to the installation surface of cover in the oil mist and clean specification models.

Be sure to replace the sealant if it has been dislocated and bent or crushed and does not return to its original shape.

5.3.7 Replacing the backup battery

An absolute encoder is used for the position detector, so while power of controller is turned off the position must be saved by the backup battery. The controller also uses a backup battery to save the program, etc. The battery is the lithium battery. These batteries are installed when the robot is shipped from the factory, but as these are consumable parts, they must be replaced periodically by the customer.

The guideline for replacing the battery is one year, but this will differ according to the robot's usage state. There exists the kinds of the errors about the battery shown in

Table 5-8

. If error 7500 occurs, please exchange the battery of the robot arm and the controller simultaneously.

Maintenance and inspection procedures

5 Maintenance and Inspection

(1) Replacing the battery (robot arm)

CAUTION

The power supply for the encoder is supplied by cable connected with battery board.

The cable must be connected while replacing the battery or operating usually. Thus, if the cable connection is incomplete, the encoder position data will be lost, and reset

ting the origin is necessary.

CAUTION

Replace the battery one by one . If all batterys are removed the encoder data will be lost, and resetting the origin is necessary.

The battery installation position is shown in Fig. 5-18

. Refers to the figure and replaces the batteries in the following procedures.

Fig.5-18 : Replacing the battery

1) Turn the controller control power OFF.

2) Remove the six fixing screws <1>, and remove the battery cover <2>.

3) Remove the old battery from the holder, and disconnect the lead connector.

4) Insert the new battery into the holder, and connect the lead connector. Replace all batteries with new ones at the same time.

5) Replaces the backup battery one by one in the above-mentioned procedure.

6) All the batteries should check that it has been exchanged newly. If the old battery is contained, generating heat and damaging may occur.

7) Install the battery cover <2> as before. Be careful so that the cable may not be inserted.

8) Initialize the battery consumption time.

Always carry out this step after replacing the battery, and initialize the battery usage time. Refer to the sep

arate "Instruction Manual/Detailed Explanation of Functions and Operations" for details on the operation methods.

[Note] If the reason for replacement is power down of the battery, resetting the origin is necessary. ( Page 95, "5.6

5.4 About Overhaul

Robots which have been in operation for an extended period of time can suffer from wear and other forms of deterioration. In regard to such robots, we define overhaul as an operation to replace parts running out of speci

fied service life or other parts which have been damaged, so that the robots may be put back in shape for contin

ued use. Overhaul interval for robots presumably varies with their operating conditions and thus with the degree of the equipment's wear and loss of performance. As a rule of thumb, however, it is recommended that overhaul be carried out before the total amount of servo-on time reaches the predetermined levels (24,000 hours for the robot

body and 36,000 hours for the controller). (See Fig. 5-19

.) For specific information about parts to be replaced and timing of overhaul, contact your local service representative.

5.6.3 ABS origin method

When the origin setting of the robot is performed for the first time, this product records the angular position of the origin within one rotation of the encoder as the offset value. If the origin setting is performed according to the

ABS origin method, this value is used to suppress variations in the origin setting operations and to reproduce the initial origin position accurately.

This operation is carried out with the teaching pendant. Set the mode of the controller to "MANUAL", and set the

[ENABLE] switch on the teaching pendant to "ENABLE" to enable the teaching pendant.

First, set to the ABS mark arrow of the axis for which the origin is to be set with jog operation. This can be set for all axes simultaneously or each axis independently.

When setting the ABS mark, always view the operations from the mark, and set at the end of the triangular mark.

The positions where the ABS mark is attached are shown in below. Refer to

Page 29, "2.4 Confirming the operation"

for details on the jog operation.

Note that if the ABS marks are peeled off, the positions can be matched using the following alternative methods.

*Match the ruling lines of the ABS mark mounting position surfaces.

5.6.4 User origin method

CAUTION

Before using this method, the origin must be set with the other method.

The setting method is explained in Page 95, "Table 5-11 : Origin setting method"

.

The procedure for setting the origin with the user origin method is explained below.

This operation is carried out with the teaching pendant. Set the mode of the controller to "MAMNUAL", and set the [ENABLE] switch on the teaching pendant to "ENABLE" to enable the teaching pendant.

The operation method is shown below.

When setting the origin for the first time using this method, carry out the operations in order from step 1). For the second and following time, move the robot arm to the user origin position with jog operation, and accurately position all axis. Then start the procedure from step 4).

1) Determine the user origin position

Move the robot to the position to be set as the origin with jog operation. Refer to Page 29, "2.4 Confirming the operation" for details on the jog operation.

CAUTION

Choose the user origin position as the position where it doesn't move by the gravity.

This position is left as a guideline to position all axes with jog operation when setting the origin again with this method.

2) Enter the JOINT jog mode, and display the joint coordinates on the teaching pendant screen. Record the value of the axis for which the origin is to be set.

3) Input the value recorded in the "user designated origin parameter (USRORG)".

The parameter details and input methods are described in the separate "Instruction Manual/Detailed Explanation of Functions and Operations". Refer to that manual and input the user designated origin position.

Appendix 1 : Configuration flag

The configuration flag indicates the robot posture.

For the 6-axis type robot, the robot hand end is saved with the position data configured of X, Y, Z, A, B and C.

However, even with the same position data, there are several postures that the robot can change to. The posture is expressed by this configuration flag, and the posture is saved with FL1 in the position constant (X, Y, Z, A, B, C)

(FL1, FL2).

The types of configuration flags are shown below.
