  X direction, and the index finger in the positive Y direction. The iTNC 530 can control up to 18 axes. The axes U, V and W are secondary linear axes parallel to the main axes X, Y and Z, respectively.

• Page 94: Polar Coordinates

  Polar coordinates If the production drawing is dimensioned in Cartesian coordinates, you also write the NC program using Cartesian coordinates. For parts containing circular arcs or angles it is often simpler to give the dimensions in polar coordinates. While the Cartesian coordinates X, Y and Z are three-dimensional and can describe points in space, polar coordinates are two-dimensional and describe points in a plane.

• Page 95: Absolute And Incremental Workpiece Positions

  G91 Y = 10 mm G91 Y = 10 mm Absolute and incremental polar coordinates Absolute polar coordinates always refer to the pole and the reference axis. Incremental coordinates always refer to the last programmed nominal position of the tool. HEIDENHAIN iTNC 530…

• Page 96: Setting The Datum

  The fastest, easiest and most accurate way of setting the datum is by using a 3-D touch probe from HEIDENHAIN. See “Setting the Datum with a 3-D Touch Probe” in the Touch Probe Cycles User’s Manual.

  6.1 Tool Movements Path functions A workpiece contour is usually composed of several contour elements such as straight lines and circular arcs. With the path functions, you can program the tool movements for straight lines and circular arcs. Miscellaneous functions M With the TNC’s miscellaneous functions you can affect The program run, e.g., a program interruption The machine functions, such as switching spindle rotation and…

  The tool retains the Z coordinate and moves in the XY plane to the position X=70, Y=50 (see figure). Three-dimensional movement The program block contains three coordinates. The TNC thus moves the tool in space to the programmed position. Example: N50 G01 X+80 Y+0 Z-10 * HEIDENHAIN iTNC 530…

• Page 210
  Entering more than three coordinates The TNC can control up to 5 axes simultaneously (software option). Machining with 5 axes, for example, moves 3 linear and 2 rotary axes simultaneously. Such programs are too complex to program at the machine, however, and are usually created with a CAM system.

3 Code Numbers

3.1Introduction

With code numbers …

Certain areas of the hard disk

Certain file types

Certain functions

… can be called.

DANGER

Code numbers may only be passed on and/or used by trained service technicians. Inexpert handling may result in the loss of important data, in a faulty machine performance and thus lead to damage or injury to property or persons.

3.2Overview

3.3Notes on Entering the Code Numbers

Keep the code numbers in confidence!

Code numbers can only be entered in the Programming and Editing mode.

The screen must be blank or the file editor is displayed.

The program manager must not be open (pressing the MOD key would activate the interface settings screen).

Press MOD and enter the code number. Finish with ENTER.

Enter and confirm code number

Note

The machine manufacturer can define own MP and PLC code numbers. In this case the HEIDENHAIN code numbers do not function any longer. —> Contact your machine manufacturer.

As long as the machine parameter list is in the editor no further code number can be entered. I.e., first close the MP list when you want to enter a new code number

When certain code numbers are entered, new soft keys are displayed, e.g., MP EDIT, PLC EDIT, OSCI.

With these soft keys you can also change to the corresponding areas without having to enter the code number again.

After you have entered the code number for the machine parameters the PLC tree can be seen in the program manager. Only files with the ending .MP are displayed.

After you have entered the PLC code number, all files of the PLC tree can be seen and loaded into the editor. However, to edit machine parameters, the soft key MP EDIT needs to be pressed.

When you have finished your work do not forget to delete all code-number soft keys (MP EDIT, PLC EDIT, OSCI, etc.) —> Enter code number 0, confirm with ENTER and exit the codenumber page with END or reboot the control.

(if this key is pressed again, the window will be closed)

If the service technician presses the HELP key a window is shown that describes the cause of error and possibilities of corrective action in addition to the displayed error message. This support can also be realized for PLC error messages by the machine manufacturer!

Note

HELP texts cannot be displayed any more for error messages in red windows. The control is not in operating condition any more. It must be rebooted.

Information on these errors can be found in the list of NC error messages; See “List of NC Error Messages” on page 22.

4.3ERR Key

Display all pending error messages

(if this key is pressed again, the window will be closed)

If there is an AND symbol (little red roof) in the header in addition to the error message, there is more than one pending error message.

The ERR key (ERROR) is located directly over the HELP key. If this key is pressed, an error list appears. All pending NC and PLC error messages of the control are displayed in an own window. In addition, the help window can be called with the HELP key.

Note

If there is no ERR key over the HELP key on your keyboard, press the corresponding space bar over the HELP key. —> If the NC software of the iTNC 530 supports the function of the ERR key, the ERR list can also be called!

The ERR window is described below:

The individual error messages can be selected with the cursor; the open help window shows the appertaining text.

4.4CE Key

Delete the error message

Displayed error messages can be acknowledged with the CE key.

The control must be rebooted.—> Press the END key.

If this does not function … —> Switch the power switch of the machine off and on again.

4.5List of NC Error Messages

You can find the complete list of NC error messages (incl. operation errors) on the DVD TNCguide in several languages and sorted by error numbers. These TNCguide information can also be found on our website http://www.heidenhain.de/Services/…

Note

Where it is possible and makes sense, you may switch the control off and on again to observe whether the error message is generated again afterwards.

Note:

In the next version of this Service Manual the list of NC error messages will be filtered for error messages that indicate a technical defect.

Information and links to suitable routines for error diagnosis will be included!

5 Errors

5.1Introduction

Not all error conditions on the control or machine can be shown by error messages on the monitor.

Therefore, this chapter gives you an overview of errors with notes and tips how to proceed.

What is the cause of Ask the last operator or technician who has worked with or on the machine about the course the error? of events.

Have there been any particular incidences, such as …

Cleaning of the machine (humidity, etc.)

Thunderstorms

Modifications to the machine

NC software update

New machining program

Tool breakage

Collision

Power failure

Etc.

The error diagnosis will be easier for you by pointed questions and precise answers!

5.2Notes and Tips

Connectors and Observe the following during connecting and disconnecting:

females

D-Sub Connectors or Females

Connect and disconnect straightly! Otherwise, the spring contact in the D-sub connectors could be widened. This may result in contact problems!

Ribbon Connectors or Females

Connect carefully and straightly with constant pressure to prevent a deflection of the males.

Signal Socket at the Motor

Slide the nib of the connector into the notch of the signal socket and screw the connector straightly. Do not use force! Otherwise the males could be bent or even pressed into the socket.

Note

It is not sufficient to deactivate a suspicious axis with machine parameter MP10 (without disconnecting suspicious units).

The corresponding units (e.g., position encoder for this axis) are not monitored any more but are still supplied with power. The defective scale can thus influence the low voltages of the control, for example!

Note

If you are not in a position/allowed to activate the axes with MP10, MP subfiles might be active and/or this is not permitted by the PLC program. —> Ask the machine manufacturer!

Switch on the control and check whether errors still occur.

Caution

For trouble shooting do not connect obviously defective controls (e.g., position encoder with short circuit after entering of humidity) to other input connectors (z.B. X1-X6, X35-X38) of the control.

Defective cables may result in interruptions but also in undefined conditions and direct error messages. Therefore, especially check possible worn and squeezed positions of the cables.

Caution

If HEIDENHAIN expansion boards for the SIMODRIVE system are used, please check the mandatory grounding.

—> See “Important Notes on the Use of HEIDENHAIN Interface Boards in SIMODRIVE System” on page 29.

Make sure that …

There is a minimum distance of 20 cm from the MC 42x(B), CC 42x and its leads to interfering equipment.

There is a minimum distance of 10 cm from the MC 42x(B), CC 42x and its leads to cables that carry interference signals. For cables in metallic ducting, adequate decoupling can be achieved by using a grounded separation shield.

The cross section of potential compensating lines is min. 6 mm2.

Contact the machine manufacturer if these conditions are not fulfilled!

5.3Overview of Possible Errors

This table shows an overview of specific errors on the machine or control, possible causes of the errors as well as measures for correcting these errors.

The potential measures for correcting the errors are described in more detail in the corresponding chapters.

Note

Where it is possible and makes sense, you may switch the control off and on again to observe whether the error is generated again afterwards.

5.4Important Notes on the Use of HEIDENHAIN Interface Boards in SIMODRIVE System

Interface boards without metallic insulation are recognized as follows:

On the front panel there are the LEDs NB (not ready) and IF (pulse release).

There is no grounding screw on the front panel.

There is no transformer on the front panel.

These board have the Id.Nr. 291070-01, 324952-01, 02, 03 and 10 without index A.

Caution

The terminal X131 of the Siemens E/R module of boards without metallic insulation may not be connected to the central signal ground of the machine!

Note

The HEIDENHAIN interface boards of the first generation were built without metallic insulation.

Interface boards with metallic insulation are distinguished as follows:

On the front panel there are the LEDs RESET X1, READY and RESET X2.

There is a grounding screw on the front panel.

There is no transformer on the front panel.

These boards have the ID 324952-10 with index

A, 11, 12, …

Transformer component on the board

Grounding screw on the front panel

Siemens UEB module with X131

Caution

If a Siemens E/R module is used together with the so-called monitoring module (UEB module) , the terminal X131 on this module has to be wired as on the E/R module!

Version with ribbon HEIDENHAIN interface boards for the SIMODRIVE system in the version with ribbon cable have cable connector a metallic insulation of the HEIDENHAIN PWM signals to the Siemens interface.

Thus X131 of the Siemens drive system must be wired!

6 Log

6.1General

The log serves as a troubleshooting aid.

For this purpose 4 MB memories are reserved in the control.

Error messages and keystrokes are recorded in a process memory. If you intend to perform tests and to see the entries in the log, you have to call it each time again.

Error messages and key strokes are stored in the log.

The sources of the keystrokes are entered in INFO: MAIN KEYSOURCE: <source>. <source> may include following entries:

—KEYBOARD

—PLC

—PLCNCSTART

—HANDWHEEL

—LSV2

Note

The first soft key (down left on the screen) is recorded in the log as soft key 0, the second soft key as soft key 1, etc.

The arrow keys for the switching of the soft-key rows are recorded. Any newly called soft-key row starts again with soft key 0.

All entries show the date and the local time.

The machine manufacturer can use up to 8 additional OEM logs. —> If necessary, ask your machine manufacturer if these OEM logs are used and which information is available for the service technician.

Note

Following messages are not shown in the log:

File system error x

Reason: In case of a write or read error all write activities on the hard disk are always interrupted as data cannot be written reliably any more.

Relay external DC voltage missing

Reason: This message is always displayed on the monitor after confirming the message Power interrupted. This is an information, not an error message. An entry in the log is not made.

6.2Calling the Log

Enter the code number LOGBOOK. —> See “Code Numbers” on page 13.

The following screen is displayed:

If you wish, you may change the path and the file name in this selection window.

Default setting: TNC:LOGBOOK.A.

Here you can also define the starting point and the end point for reading out the log.

Note

Ensure correct spelling when making any changes in the log window!

Then start reading out the log by pressing the EXECUTE soft key.

An ASCII file with the log entries is generated and displayed on the screen!

Note

The log can be read out directly from the PC/laptop with the HEIDENHAIN software tool TNCremoNT. The code number LOGBOOK has not to be entered on the control.

The local time on the control and the PC/laptop should be identical!

6.3Overview of Log Entries

a. Control-in-operation symbol = «* » in the screen display

a.For testing all LSV-2 telegrams can be entered in the log. This function has to be released after entering the code number LOGBOOK via soft key LSV-2 TELEGRAM ON OFF .
