Assembly of all bearings Follow the instructions below when mounting a bearing on the manipulator. 1. To avoid contamination, let a new bearing remain in its wrapping until it is time for fitting. 2. Ensure that all parts included in the bearing fitting are free from burrs, grinding waste and other contamination. Cast components must be free from foundry sand. 3. Bearing rings, inner rings and roller elements must under no circumstances be subjected to direct impact. Furthermore, the roller elements must not be exposed to any stresses during the assembly work. Assembly of tapered bearings Follow the previous instructions for assembly of all bearings, when mounting a tapered bearing on the manipulator. In addition to those instructions, the procedure below must be carried out to enable the roller elements to adjust to the correct position against the race flange. 1. Tension the bearing gradually until the recommended pre-tension is achieved. Note! The roller elements must be rotated a specified number of turns before pretensioning is carried out and also rotated during the pre-tensioning sequence. 2. Make sure the bearing is properly aligned, as this will directly affect the lifespan of the bearing. Greasing of bearings The bearings must be greased after assembly, according to instructions below: •

The bearings must not be completely filled with grease. However, if space is available beside the bearing fitting, the bearing may be totally filled with grease when mounted, as excessive grease will be pressed out from the bearing when the robot is started.

•

During operation, the bearing should be filled to 70-80% of the available volume.

•

Ensure that grease is handled and stored properly, to avoid contamination.

Grease the different types of bearings as detailed below: •

5 Calibration information 5.1. Introduction

5 Calibration information 5.1. Introduction General This chapter includes general information about different calibration methods and details also procedures that does not require specific calibration equipment. When the robot system must be recalibrated, it is done according to documentation enclosed with the calibration tools. When to calibrate The system must be calibrated if any of the below occurs. The resolver values are changed If resolver values are changed, the robot must be recalibrated using the calibration methods supplied from ABB. Calibrate the robot carefully with standard calibration. The different methods are briefly described in section Calibration methods on page 184, and further detailed in separate Calibration manuals. If the robot has Absolute Accuracy calibration, it is also recommended but not always needed to be calibrated for new Absolute Accuracy. The resolver values will change when parts affecting the calibration position are replaced on the robot, e.g. motors, wrist or part of transmission. Contents of the revolution counter memory are lost If the contents of the revolution counter memory are lost, the counters must be updated as detailed in section Updating revolution counters on page 189. 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 has been rebuilt, e.g. after a crash or when the robot has been changed for other reachability, it needs to be recalibrated for new resolver values. If the robot has Absolute Accuracy calibration, it needs to be calibrated for new Absolute Accuracy. References The article numbers for the Calibration manuals are listed in section Document references in the Product manual (part 2 of 2), reference information. Article numbers for the calibration tools are also listed in part 2 of the Product manual.

5.2. Calibration methods Overview This section specifies the different types of calibration and the calibration methods that are supplied from ABB. Types of calibration Type of calibration

Description

Calibration method

Standard calibration

The calibrated robot is positioned at home position, i.e. the axes positions (angles) are set to 0º. Standard calibration data is found in the file calib.cfg, supplied with the robot at delivery. The file identifies the correct resolver/motor position corresponding to the robot home position. From deliveries together with RobotWare 5.0.5 and higher, the data will instead be found on the SMB (serial measurement board) in the robot, and not in a separate file.

Calibration Pendulum (standard method) or Levelmeter calibration (alternative method)

Absolute Accuracy calibration (optional)

Based on standard calibration, but besides CalibWare positioning the robot at home position, the Absolute Accuracy calibration also compensates for: • mechanical tolerances in the robot structure • deflection due to load. Absolute Accuracy calibration focuses on positioning accuracy in the Cartesian coordinate system for the robot. Absolute Accuracy data is found in the file absacc.cfg, supplied with the robot at delivery. The file replaces the calib.cfg file and identifies motor positions as well as absacccompensation parameters. From deliveries together with RobotWare 5.0.6 and higher, the data will instead be found on the SMB (serial measurement board) in the robot, and not in a separate file. A robot calibrated with AbsAcc has a sticker next to the identification plate of the robot. To regain 100% Absolute Accuracy performance, the robot must be recalibrated for Absolute Accuracy!

5 Calibration information 5.2. Calibration methods

Calibration methods Each calibration method is detailed in separate manuals. Below is a brief description of the methods available. Calibration Pendulum - standard method Calibration Pendulum is the standard method for calibration of all ABB robots (except IRB 6400R, IRB 640, IRB 1400H and IRB 4400S) and is also the most accurate method for the standard type of calibration. It is the recommended method in order to achieve proper performance. The calibration equipment for Calibration Pendulum is delivered as a complete toolkit, including the manual Calibration Pendulum Instruction. 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 has not as good 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 therefor not recommended. The calibration equipment for Levelmeter Calibration is ordered as separate parts for each robot and the manual Instruction for Levelmeter Calibration is enclosed with the Levelmeter 2000. CalibWare - Absolute Accuracy calibration In order to achieve a good positioning in the Cartesian coordinate system, Absolute Accuracy is used as a TCP calibration. The tool CalibWare guides through the calibration process and calculates new compensation parameters. This is detailed further in the manual xx. If a service operation is done to a robot with Absolute Accuracy, a new absolute accuracy calibration is required in order to establish full performance. For most cases after motor and transmission replacements that do not include taking apart the robot structure, standard calibration is sufficient. Standard calibration also supports wrist exchange.

5 Calibration information 5.4. Calibration movement directions for all axes

5.4. Calibration movement directions for all axes Calibration movement directions When calibrating, the axis must consistently be run towards the calibration position in the same direction, in order to avoid position errors caused by backlash in gears etc. Positive directions are shown in the figure below. This is normally handled by the robot calibration software. Note! The figure shows an IRB 7600, but the positive direction is the same for all robots, except the positive direction of axis 3 for IRB 6400R which is in the opposite direction!

5 Calibration information 5.5. Updating revolution counters

5.5. Updating revolution counters General This section details how to perform a rough calibration of each robot axis, i.e. updating the revolution counter value for each axis, using either the TPU or the FlexPendant. Manually running the robot to the calibration position This procedure details the first step when updating the revolution counter; manually running the robot to the calibration position. Step

Action

Note

1.

Select axis-by-axis motion mode.

2.

Jog the robot so that the calibration marks lie Shown in section Calibration scales within the tolerance zone. and correct axis position on page 186.

3.

When all axes are positioned, store the revolution counter settings.

Detailed in sections: Storing the revolution counter setting with the TPU on page 190 (RobotWare 4.0). Storing the revolution counter setting with the FlexPendant on page 191 (RobotWare 5.0).

Correct calibration position of axis 4 and 6 When running the robot to calibration position, it is extremely important to make sure that axes 4 and 6 of the below mentioned robots are positioned correctly. The axes do not have any mechanical stops and can therefore be calibrated at the wrong turn. Make sure the axes are positioned according to the correct calibration values, not only according to the calibration marks. The correct values are found on a label, located either on the lower arm or underneath the flange plate on the base. At delivery the robot is in the correct position, do NOT rotate axis 4 or 6 at power up before the revolution counters are updated. If one of the below mentioned axes are rotated one or more turns from its calibration position before updating the revolution counter, the exact calibration position will be lost due to uneven gear ratio. This affects the following robots:
