ESD directives

ESD = electrostatic sensitive devices e.s.d. = electrostatic discharge

ESDs can be destroyed by voltages which are imperceptible to humans. As well as causing complete failure of components, e.s.d. can also be responsible for partial damage to an IC or component, which can reduce its service life or lead to sporadic faults. For these reasons, not only new modules, but also defective modules, must be handled very carefully in a way suitable for ESDs.

ESD directives

Handling ESD modules: • Components should only be unpacked if a) you are wearing ESD shoes or b) you are wearing ESD shoe grounding strips or c) you are grounded by means of an ESD armband. • Before touching an electronic module you should discharge the voltage from your own body. • Do not place electronic modules near monitors. • Only measure with grounded measuring instruments or discharge the measuring head before measuring.

7. Mastering

handout GP KR C2 V4.1 01.03.01

Page 73 of 227

Why is mastering carried out? A3=+90° A4, A5, A6=0°

• When the robot is mastered, the axes are moved into a defined mechanical position, the so-called mechanical zero position. A2=-90°

• Once the robot is in this mechanical zero position, the absolute encoder value for each axis is saved.

A1=0°

I 14.03.02 I College I ML I 1

Mastering equipment

• In order to move the robot exactly to the mechanical zero position, a dial gauge or electronic measuring tool (EMT) is used.

Electronic measuring tool (EMT) In EMT mastering, the axis is automatically moved by the robot controller to the mechanical zero position. If a dial gauge is being used, this must be carried out manually in axis-specific mode.

Reasons for remastering

Mastering is canceled...

The robot is to be mastered... ...after repairs (e.g. replacement of a drive motor or RDC)

... automatically on booting the system1)

…replacement of a gear

... manually by the operator

...when the robot has been moved without the controller (e.g. hand crank)

... automatically on booting the system1)

...after an impact with a mechanical end stop at more than manual velocity (25 cm/s)

... manually by the operator

...after a collision involving the tool or robot

... manually by the operator

1)

If discrepancies are detected between the resolver data saved when shutting down the controller and the current position, all mastering data are deleted for safety reasons.

The robot can be unmastered...

Mastering is canceled...

... if the mastering values for the individual axes are to be specifically deleted

... manually by the operator

The X Y Z - 4 Point method

In the XYZ - 4-point method, the TCP of the tool is moved to a reference point from four different directions.

The TCP of the tool is then calculated from the different flange positions and orientations.

Archive

This function allows you to save important data to floppy disk. All files are saved in compressed form as ZIP files.

If you try to insert a file in an existing archive, the robot name is checked. The robot name in the archive is compared with the name that is set in the controller. If the two names are different, a request for confirmation is generated asking if you really wish to overwrite the existing archive.

Fixed tool

"Fixed tool" means that the robot guides a workpiece to one or more stationary tools that are integrated into the cell. Calibration consists of two parts:

Z Y Z

X

• Calculation of the distance between the TCP of the fixed tool and the origin of the world coordinate system.

Z Y X Y

• The workpiece is mounted on the robot flange and calibrated as a BASE.

Subprograms

Subprograms are used for identical program sections that are repeated frequently.

• Subprograms reduce the amount of typing during programming. • Subprograms reduce the program length thus making the program more transparent. • Subprograms can be reused in other programs. • Subprograms can be used for structuring a program.

Exercise: Subprograms (complex program) Tasks: • • • •

The programs from exercises 11 and 13 are now to be expanded so that a single program selection suffices to execute the entire procedure: fetch plastic panel, apply adhesive and put plastic panel back down again. Create a new program “PANEL” in which all program sections are executed. Proceed in the same way with the programs from exercises 6 and 7. Create a new program “COM_PATH” in which motions are executed for both paths.
