Requirements, foundation

The table shows the requirements for the foundation where the weight of the installed robot is included:

Requirement

Flatness of foundation surface

Maximum tilt

Minimum resonance frequency

Value

0.3 mm

Note

Flat foundations give better repeatability of the resolver calibration compared to original settings on delivery from ABB.

The value for levelness aims at the circumstance of the anchoring points in the robot base.

0°

Note

It may affect the manipulator lifetime to have a lower resonance frequency than recommended.

The value is recommended for optimal performance.

Due to foundation stiffness, consider robot mass including equipment.

i

For information about compensating for foundation flexibility, see Application manual - Controller software IRC5 , section Motion Process Mode .

i

The minimum resonance frequency given should be interpreted as the frequency of the robot mass/inertia, robot assumed stiff, when a foundation translational/torsional elasticity is added, i.e., the stiffness of the pedestal where the robot is mounted. The minimum resonance frequency should not be interpreted as the resonance frequency of the building, floor etc. For example, if the equivalent mass of the floor is very high, it will not affect robot movement, even if the frequency is well below the stated 25 Hz. The robot should be mounted as rigid as possibly to the floor.




51




Continued

Disturbances from other machinery will affect the robot and the tool accuracy. The robot has resonance frequencies in the region 10 – 20 Hz and disturbances in this region will be amplified, although somewhat damped by the servo control. This might be a problem, depending on the requirements from the applications. If this is a problem, the robot needs to be isolated from the environment.

Storage conditions, robot

The table shows the allowed storage conditions for the robot:

At low environmental temperature (< 10° C) a warm-up phase is recommended to be run with the robot, as with any other machine. Otherwise there is a risk that the robot stops or run with lower performance due to temperature dependent oil- and grease viscosity.

2.3.3 Risk of tipping/stability

2.3.3 Risk of tipping/stability

Risk of tipping

If the robot is not fastened to the foundation while moving the arm, the robot is not stable in the whole working area. Moving the arm will displace the center of gravity, which may cause the robot to tip over.

The shipping position is the most stable position.

Do not change the robot position before securing it to the foundation!

Shipping and transportation position

This figure shows the robot in its shipping position and transportation position.

xx0900000167

WARNING

The robot is likely to be mechanically unstable if not secured to the foundation.

2.4.8 Setting the system parameters for a suspended or tilted robot

2.4.8 Setting the system parameters for a suspended or tilted robot

General

The robot is configured for mounting parallel to the floor, without tilting, on delivery.

The method for mounting the robot in a suspended (upside down) or tilted position is basically the same as for floor mounting, but the system parameters that describe the mounting angle (how the robot is oriented relative to the gravity) must be re-defined.

Note

With suspended installation, make sure that the gantry or corresponding structure is rigid enough to prevent unacceptable vibrations and deflections, so that optimum performance can be achieved.

Note

The allowed mounting positions are described in the product specification for the robot. The requirements on the foundation are described in

Requirements, foundation on page 51

.

System parameters

Note

The mounting angle must be configured correctly in the system parameters so that the robot system can control the movements in the best possible way. An incorrect definition of the mounting angle will result in:

• Overloading the mechanical structure.

• Lower path performance and path accuracy.

• Some functions will not work properly, for example Load Identification and

Collision detection .

Gravity Alpha

If the robot is mounted on a wall (rotated around the x-axis), then the robot base frame and the system parameter Gravity Alpha must be redefined. The value of

2.4.13 Loads fitted to the robot, stopping time and braking distances

2.4.13 Loads fitted to the robot, stopping time and braking distances

General

Any loads mounted on the robot must be defined correctly and carefully (with regard to the position of center of gravity and mass moments of inertia) in order to avoid jolting movements and overloading motors, gears and structure.

CAUTION

Incorrectly defined loads may result in operational stops or major damage to the robot.

References

Load diagrams, permitted extra loads (equipment) and their positions are specified in the product specification. The loads must be defined in the software.

• Operating manual - IRC5 with FlexPendant

Stopping time and braking distances

The performance of the motor brake depends on if there are any loads attached to the robot. For more information, see product specification for the robot.

110





2.4.14 Optimizing the performance

2.4.14 Optimizing the performance

Standard performance

The standard performance of a linear axis system should be more than enough for most material handling applications. However if the application requires higher accuracy, or if the installation is at the "weaker end" there are a number of possibilities to improve the performance. Factors affecting the performance are for example: height of the legs, position of the legs, length of the movement, speed, robot arm position, tool design, and floor stiffness.

CAUTION

If two IRB 6620LX are mounted on the same linear axis, then they may influence each other causing vibrations. Therefore, is the securing of the frame support extra important for applications where even small vibrations can cause disturbances.

How to improve performance

Improve the stability of the installation

The most important factor is the configuration of the legs. Installations with long distance between the legs in combination with high legs are more unstable. The floor stability and attachment of the lower legs are also important factors. The performance will in general be better when the robot is at a position close to a leg.

See Product specification - IRB 6620 , and Product specification - Linear Axis .

Reduce the acceleration

The instruction AccSet can be used in the RAPID program to temporarily reduce the acceleration and thus vibration of the system. This is especially efficient during shorter movements.

For example, AccSet 50, 25 will limit the acceleration to 50% of the normal value and the ramp (acceleration rate) to 25% of the normal value.

Use reduced acceleration during the more sensitive movements and increase the value to the default ( AccSet 100, 100 ) during longer movements or when the need of accuracy is less important.

For more information about AccSet see Technical reference manual - RAPID

Instructions, Functions and Data types .





111


2.4.14 Optimizing the performance

Continued

Optimize the servo control

The argument Type in the instruction TuneServo can be defined as TUNE_DF to improve the accuracy, by damping oscillations of the axes due to mechanical resonances.

TUNE_DF can be adjusted within the RAPID program during execution.

This means that you can have different settings for

TuneServo for different robot positions and movements. Adjusting TUNE_DF correctly will not affect the cycle time and path accuracy in any negative way.

Tip

The ABB software TuneMaster is a good tool for finding the optimal value of

TUNE_DF .

TuneMaster is included in the RobotWare distribution.

The argument Type in the instruction TuneServo can be defined as TUNE_DH to improve the smoothness of the robot path, by decreasing the effective bandwidth.

Using TUNE_DH affects the path in corner zones, increasing the cycle time in fine points but not along the entire path.

For more information about TuneServo see Technical reference manual - RAPID

Instructions, Functions and Data types .

2.4.16 Automatic lubrication system

2.4.16 Automatic lubrication system

Power source for the lubrication system

The lubrication system for the linear axis is powered either by battery or by cable from external power source, depending of which option is chosen at delivery. IRC5 can control the lubrication if option 1070-1 for IRC5 is selected. Read more in

Product manual - IRC5 .

Handling the signal from the grease level sensor

The grease level sensor reports a completed cycle of the progressive distributor by changing the pulse twice. The software has to react on the second change of pulse.

The sensor can be connected either to the robot controller or to a PLC. Code must be written to handle the signal.

Setting up the lubrication interval

The general recommendation is to start with a time interval of 150 hours or a length interval of 100 km for the lubrication. These values are to be used for normal room conditions regarding temperature, humidity and dust. If the conditions are more severe, shorter intervals should be used.

The flat rails and rack should be “wet” and have a thin oil film but not be soaked.

If the lubrication is correctly adjusted a few floor drips may occur but not much more.


114





2.4.16 Automatic lubrication system

Continued

Activating the lubrication and detecting lubrication errors

The recommendation is to send 5 pulses (10s) to the lubrication pump every 5 min or until the sensor responds. The sensor response at a successful lubrication is to change the output value twice. The initial output value can be either 0 or 1. This gives two scenarios for a completed sensor feedback: 0-1-0 or 1-0-1. In other words, a correct sensor feedback after a completed lubrication cycle will be that the sensor is changing the output value twice.

If no response has been received from the sensor after 5 pulses and 25 min, an error has occurred.

3.4.9 Replacing the SMB battery

Note

The battery low alert (38213 Battery charge low ) is displayed when the battery needs to be replaced. The recommendation to avoid an unsynchronized robot is to keep the power to the controller turned on until the battery is to be replaced.

For an SMB board with 3-pole battery contact (RMU101 3HAC044168-001 or

RMU102 3HAC043904-001), the lifetime of a new battery is typically 36 months.

For an SMB board with 2-pole battery contact, the typical lifetime of a new battery is 36 months if the robot is powered off 2 days/week or 18 months if the robot is powered off 16 h/day. The lifetime can be extended for longer production breaks with a battery shutdown service routine. See Operating manual - IRC5 with

FlexPendant for instructions.

Action

Finish the refitting procedure of the motor or gear in question.

Note

Remove the upper oil plug on the gear and replace it with the leak-down tester.

Regulators, which are included in the leak-down test, may be required.

Use caution, apply compressed air and raise the pressure with the knob until the correct value is shown on the manometer.

Correct value:

0.2-0.25 bar (20-25 kPa)

CAUTION

The pressure must under no circumstance be higher than 0.25 bar (20-25 kPa). Also during the time when the pressure is raised.

Disconnect the compressed air supply.

Wait for approximately 8-10 minutes and make sure that no pressure loss occurs.

If the compressed air is significantly colder or warmer than the gearbox to be tested, a slight pressure increase or decrease may occur. This is quite normal.

If any pressure drop occurred, then localize the leak as described in step

7 .

If no pressure drop occurred, then remove the leakdown tester and refit the oil plug. The test is complete.

Spray any suspected leak areas with the leak detection spray. Bubbles indicate a leak.

When the leak has been localized, take the necessary measures to correct the leak.

Definition

A collective term for several methods that might be available for calibrating the ABB robot. Each method contains calibration routines.

Known position of the complete robot where the angle of each axis can be checked against visual synchronization marks.

Known position of the complete robot that is used for calibration of the robot.

A generic term for all calibration methods that aim to move the robot to calibration position.

A calibration routine that generates a new zero position of the robot.

A calibration routine that in the first step generates a reference to current zero position of the robot. The same calibration routine can later on be used to recalibrate the robot back to the same position as when the reference was stored.

This routine is more flexible compared to fine calibration and is used when tools and process equipment are installed.

Requires that a reference is created before being used for recalibrating the robot.

Requires that the robot is dressed with the same tools and process equipment during calibration as during creation of the reference values.

A calibration routine to make a rough calibration of each manipulator axis.

Visual marks on the robot axes. When marks are aligned, the robot is in synchronization position.

5.1.2 Calibration methods

5.1.2 Calibration methods

Overview

This section specifies the different types of calibration and the calibration methods that are supplied by ABB.

Types of calibration

Type of calibration Description Calibration method i

Standard calibration The calibrated robot is positioned at calibration position.

Standard calibration data is found on the SMB

(serial measurement board) or EIB in the robot.

For robots with RobotWare 5.04 or older, the calibration data is delivered in a file, calib.cfg, supplied with the robot at delivery. The file identifies the correct resolver/motor position corresponding to the robot home position.

Axis Calibration or Calibration Pendulum i

Levelmeter calibration

(alternative method)

The robot is calibrated by either Calibration Pendulum or Axis Calibration at factory. Always use the same calibration method as used at the factory.


If no data is found related to standard calibration, Calibration Pendulum is used as default.

Brief description of calibration methods

Calibration Pendulum method

Calibration Pendulum is a standard calibration method for calibration of all ABB robots (except IRB 6400R, IRB 640, IRB 1400H, and IRB 4400S).

Two different routines are available for the Calibration Pendulum method:

• Calibration Pendulum II

• Reference calibration

The calibration equipment for Calibration Pendulum is delivered as a complete toolkit, including the Operating manual - Calibration Pendulum , which describes the method and the different routines further.

Axis Calibration method

Axis Calibration is a standard calibration method for calibration of IRB 6620LX and is the most accurate method for the standard calibration. It is the recommended method in order to achieve proper performance.

The following routines are available for the Axis Calibration method:

• Fine calibration

• Update revolution counters

• Reference calibration

The calibration equipment for Axis Calibration is delivered as a toolkit.

An introduction to the calibration method is given in this manual, see

5 Calibration

5.1.2 Calibration methods

Continued

The actual instructions of how to perform the calibration procedure and what to do at each step is given on the FlexPendant. You will be guided through the calibration procedure, step by step.

Levelmeter calibration - alternative method

Levelmeter calibration is referred to as the alternative method for calibration of

ABB robots because of the less accurate values obtained during calibration. The method uses the same principles as Calibration Pendulum, but does not have as good of mechanical tolerances to the toolkit parts as the standard method with

Calibration Pendulum.

This method may, after calibration, require modifications in the robot program and is therefore not recommended.

The calibration equipment (Levelmeter 2000) for levelmeter calibration is ordered as separate parts for each robot, and includes the Operating manual - Levelmeter

Calibration , which describes the method and the different routines further.

5.1.3 When to calibrate

5.1.3 When to calibrate

When to calibrate

The system must be calibrated if any of the following situations occur.

The resolver values are changed

If resolver values are changed, the robot must be recalibrated using the calibration methods supplied by ABB. Calibrate the robot carefully with standard calibration, according to information in this manual.

The resolver values will change when parts affecting the calibration position are replaced on the robot, for example motors or parts of the transmission.

The revolution counter memory is lost

If the revolution counter memory is lost, the counters must be updated. See


. This will occur when:

• The battery is discharged

• A resolver error occurs

• The signal between a resolver and measurement board is interrupted

• A robot axis is moved with the control system disconnected

The revolution counters must also be updated after the robot and controller are connected at the first installation.

The robot is rebuilt

If the robot is rebuilt, for example, after a crash or when the reach ability of a robot is changed, it needs to be recalibrated for new resolver values.

Axis 1 calibration

Axis 1 calibration needs to be performed at installation of the robot (axes 2-6) on the linear axis (axis 1) when commissioning the complete robot system. See

Calibration and configuration of Joint Bound, axis 1 on page 305

3

Action

Select axis-by-axis motion mode.

Note

Jog the manipulator to align the synchronization marks.

See


When all axes are positioned, update the revolution counter.

Step 2 - Updating the revolution counter with the FlexPendant on page 317 .

Correct calibration position of axis 4 and 6

When jogging the manipulator to synchronization position, it is extremely important to make sure that axes 4 and 6 of the following mentioned manipulators are positioned correctly. The axes can be calibrated at the wrong turn, resulting in an incorrect manipulator calibration.

Make sure the axes are positioned according to the correct calibration values, not only according to the synchronization marks. The correct values are found on a label, located either on the lower arm, underneath the flange plate on the base or on the frame.

At delivery the manipulator is in the correct position, do NOT rotate axis 4 or 6 at power up before the revolution counters are updated.

5.5.1 Description of Axis Calibration

5.5 Calibrating with Axis Calibration method

5.5.1 Description of Axis Calibration

Instructions for Axis Calibration procedure given on the FlexPendant


This manual contains a brief description of the method, additional information to the information given on the FlexPendant, article number for the tools and images of where to fit the calibration tools on the robot.

Overview of the Axis Calibration procedure

The Axis Calibration procedure applies to all axes, and is performed on one axis at the time. The robot axes are both manually and automatically moved into position, as instructed on the FlexPendant.

A fixed calibration pin/bushing is installed on each robot axis at delivery.

The Axis Calibration procedure described roughly:

• A removable calibration tool is inserted by the operator into a calibration bushing on the axis chosen for calibration, according to instructions on the

FlexPendant.

WARNING

Calibrating the robot with Axis Calibration requires special calibration tools from ABB. Using other pins in the calibration bushings may cause severe damage to the robot and/or personnel.

WARNING

The calibration tool must be fully inserted into the calibration bushing, until the steel spring ring snaps into place.

• During the calibration procedure, RobotWare moves the robot axis chosen for calibration so that the calibration tools get into contact. RobotWare records values of the axis position and repeats the coming-in-contact procedure several times to get an exact value of the axis position.

WARNING

Risk of pinching! The contact force for large robots can be up to 150 kg.

Keep a safe distance to the robot.

• The axis position is stored in RobotWare with an active choice from the operator.

Routines in the calibration procedure

The following routines are available in the Axis Calibration procedure, given at the beginning of the procedure on the FlexPendant.

Fine calibration routine

Choose this routine to calibrate the robot when there are no tools, process cabling or equipment fitted to the robot.

Reference calibration routine

Choose this routine to create reference values and to calibrate the robot when the robot is dressed with tools, process cabling or other equipment.

Also choose this routine if the robot is wall mounted or suspended.

If calibrating the robot with reference calibration there must be reference values created before repair is made to the robot, if values are not already available.

Creating new values requires possibility to move the robot. The reference values contain positions of all axes, torque of axes and technical data about the tool installed. A benefit with reference calibration is that the current state of the robot is stored and not the state when the robot left the ABB factory. The reference value will be named according to tool name, date etc.


When reference calibration is performed, the robot is restored to the status given by the reference values.

Note

Update revolution counters

Choose this routine to make a rough calibration of each manipulator axis by updating the revolution counter for each axis, using the FlexPendant.

Validation

When calibrating the robot with the reference calibration routine, the robot must be dressed with the same tools, process cabling and any other equipment as when the reference values were created.

In the mentioned routines, it is also possible to validate the calibration data.

Position of robot axes

The axis chosen for calibration is automatically run by the calibration program to its calibration position during the calibration procedure.

In order for the axis to be able to be moved to calibration position, or in order for getting proper access to the calibration bushing, other axes might need to be jogged to positions different from 0 degrees. Information about which axes are allowed to be jogged will be given on the FlexPendant. These axes are marked with Unrestricted in the FlexPendant window.

How to calibrate a suspended or wall mounted robot

The IRB 6620LX is calibrated floor standing in factory, prior to shipping.




321


5 Calibration


Continued

To calibrate a suspended or wall mounted robot, reference calibration must be used. Reference values for a suspended or a wall mounted robot must be created with the robot mounted at its working position, not standing on a floor.

To calibrate a suspended or wall mounted robot with the fine calibration routine, the robot must first be taken down and mounted standing on the floor.

7.3 Screw joints

General

This section describes how to tighten the various types of screw joints on the IRB

6620LX.

The instructions and torque values are valid for screw joints comprised of metallic materials and do not apply to soft or brittle materials.

UNBRAKO screws

UNBRAKO is a special type of screw recommended by ABB for certain screw joints.

It features special surface treatment (Gleitmo as described below) and is extremely resistant to fatigue.

Whenever used, this is specified in the instructions, and in such cases, no other type of replacement screw is allowed. Using other types of screws will void any warranty and may potentially cause serious damage or injury.

Gleitmo treated screws

Gleitmo is a special surface treatment to reduce the friction when tightening the screw joint. Screws treated with Gleitmo may be reused 3-4 times before the coating disappears. After this the screw must be discarded and replaced with a new one.

When handling screws treated with Gleitmo, protective gloves of nitrile rubber type should be used.

Screws lubricated in other ways

Screws lubricated with Molycote 1000 should only be used when specified in the repair, maintenance or installation procedure descriptions.

In such cases, proceed as follows:

1 Apply lubricant to the screw thread.

2 Apply lubricant between the plain washer and screw head.

3 Screw dimensions of M8 or larger must be tightened with a torque wrench.

Screw dimensions of M6 or smaller may be tightened without a torque wrench if this is done by trained and qualified personnel.

Tightening torque

Before tightening any screw, note the following:

• Determine whether a standard tightening torque or special torque is to be applied. The standard torques are specified in the following tables. Any special torques are specified in the repair, maintenance or installation procedure descriptions.

Any special torque specified overrides the standard torque!

• Use the correct tightening torque for each type of screw joint.

• Only use correctly calibrated torque keys.






7.3 Screw joints
