CNC controls

How can I integrate my control into my corporate network?2023-02-19T12:24:10+00:00

If the LAN cable is connected to a switch/hub in the network, and if the IP address is set accordingly on the TNC, then the transmission of data to and from the TNC can be started through the use of the machine’s IP address with TNCremo, for example.

Who can help me with questions regarding the MillPlus?2022-07-13T16:20:08+00:00

The MillPlus was a control designed exclusively for DMG. For this reason, DMG is responsible for answering questions about the MillPlus.

How can I connect a network share to my control?2022-07-27T22:15:36+00:00

Depending on the type of network share and version, it can be made visible as a drive on the TNC. Because this process varies slightly based on the NC software, please refer to the User’s Manual.

How can I create a log file?2022-07-13T16:20:34+00:00

  • Press the ERR key
  • The LOG FILES soft key should now appear
  • Press the LOG FILES soft key

My control is old, but it still works. Does HEIDENHAIN offer an upgrade to a current control?2023-02-19T12:25:43+00:00

Please contact the HEIDENHAIN NC Support & PLC Programming Support:
TNCService@heidenhain.com

How can I correctly evaluate the temperature on the control if a replacement motor is installed with a KTY84-130 temperature sensor instead of a PT1000?2025-04-09T15:56:37+00:00

In software version 606420-04 SP12, we introduced machine parameter MP2207.x (overwrite “Type of temperature sensor” from motor table). This machine parameter can be modified as follows:

* = Entry in the motor table is active

0 = KTY84-130

1 = PT1000

In NC software 606420-04 SP5 or later, the motor table contains the entry “TEMP_SENS”. You can change this entry with a PLC authorization.

For older controls, we offer the PT1000-KTY converter (ID: 1219990-02).

How can I check the control’s statuses and run times?2022-12-15T22:12:10+00:00

This can be done with the help of software for collecting operating data. HEIDENHAIN offers StateMonitor as a solution for the TNC.

When the tool length appears in the tool table via touch-off, the difference relative to L from TOOL.T is no longer used. Instead, the value is taken directly from the ACTL display.2025-04-09T16:16:06+00:00

The behavior of the “actual position capture” key was intentionally changed for the introduction of NC software 340590-10. The value is now always taken from the value of the programmed tool axis as shown in the position display. To receive the correct value, perform the following steps:

1. Enter L=0 and DL=0 for the tool, and move the tool to the touch-off surface.

2. Press the “actual position capture” key.

The displayed value is always transferred to the table without undergoing any calculations. This process also takes the programmed tool axis into account rather than merely “Z”.

Where can I obtain end-user support for implementing new functions on my machine (e.g., for the PLC)?2022-07-13T16:12:37+00:00

We recommend contacting your machine manufacturer or a qualified retrofitter.
We can happily recommend experienced companies. Please contact TNCService@heidenhain.com

The control’s responsiveness and program run time are very slow after error 230-0490.2025-04-09T16:22:05+00:00

– SRI State Reporting Interface –
With its State Reporting Interface (SRI) software option, HEIDENHAIN offers an interface for easily making machine operating statuses available to a higher-level MES or ERP system.

In order to avoid data loss, does the control need to keep running while the buffer battery is being changed?2022-07-13T16:17:27+00:00

Newer controls (TNC 4xx or later) feature a GoldCap capacitor, which ensures that the data are buffered while the battery is being changed. However, the battery should not be removed for an extended period of time. Older controls do not have a capacitor, and their data are not saved when the control is switched off.

Is it possible to view the states of the inputs/outputs on the control?2022-07-13T16:17:54+00:00

In HSCI systems, the states of various inputs and outputs can be checked via the HSCI bus diagnostics. In non-HSCI systems, the “TABLE” soft key in the PLC (password required) allows you to check the inputs and outputs.

Where can I find the documentation for my control?2022-07-27T22:18:12+00:00

  • The User’s Manuals for NC programmers/machine operators can be found under Documentation in the download area.
  • The Technical Manuals and Service Manuals for current controls (iTNC 530 and NCK controls) are in the HEIDENHAIN Filebase for authorized customers.
  • The Technical Manuals and various service documents of older controls are available to everyone for download under Documentation.
My tool changer does not work anymore. How can I retract it?2022-07-13T16:18:18+00:00

Please get in touch with your machine manufacturer. Tool changer systems are OEM-specific hardware.

How can I back up data on my control?2022-07-27T22:17:39+00:00

Different methods are possible depending on the type of control. These possibilities are described in detail in the respective User’s Manual.

Tip: search for “data backup” in the PDF document.

The remote connection to the control is not working. What can I do about it?2022-07-13T16:19:08+00:00

Please check the following:

  1. Can the machine be reached by a ping?
  2. Is option 18 enabled?
  3. Is external access activated?
  4. Are all necessary ports enabled in the firewall?
How do I establish a connection to my control?2022-07-27T22:15:59+00:00

The easiest way to establish a connection to the TNC from a directly connected PC is with TNCremo/TNCserver.

If the TNC control already has a network card (iTNC 530 or higher), then at least one IP address must be provided. Please refer to the description in the User’s Manual, because the procedure varies slightly based on the NC software.

All of the TNC controls also feature an RS-232 interface (Recommended Standard 232). But due to its very limited capabilities and speed, this interface should be used only on older models.

I want to install an indexing head on my machine. Does this work with my HEIDENHAIN control?2022-07-13T16:19:39+00:00

Why is my programming station not recognized as a full version?2023-02-19T12:30:16+00:00

The software of the test version and full version is identical. It is enabled via a hardware dongle that is ordinarily built into the programming station keyboard. Whether this kind of dongle or an external dongle is connected depends on the given driver. The driver can be downloaded from our website free of charge but is dependent on the model. If you are unsure, then simply install both drivers.

If the dongle is displayed correctly in the Windows device manager and is still not recognized by the software, then this may be due to the following:

  • Incorrect software version; dongle license does not match
  • VirtualBox does not use the dongle properly → Check installation
  • Multiple programming station are running (the first one becomes the full version)
The VirtualBox programming station does not start after the installation. What can I do?2022-07-27T22:08:55+00:00

  1. Download the most recent version of the VirtualBox programming station of the TNC 640 from the download area in order to ensure that the installation file is up to date.
  2. Open the downloaded .zip file with a right-click.
  3. Navigate to the “Properties” context menu → “General” tab → Security (The file originates from a different computer. Access might be denied due to safety reasons.) → Click the “Unblock” checkbox.
  4. Unpack the .zip file, and then install the programming station. It is important that you have administrator permissions on the installation PC.
A message about virtualization support appears during installation of the programming station. What should I do?2025-04-09T16:26:56+00:00

The programming station installation process checks whether hardware virtualization is present and active.

Smooth operation of the programming station in conjunction with the VirtualBox virtualization software requires the availability of hardware virtualization. The processor thus needs to have the VT-x or AMD-V instruction set extension. The availability of hardware virtualization depends not only on the CPU but also on the settings in the BIOS and the Windows operating system of your PC. Be sure to consider all relevant information provided by the manufacturer!

In the Task Manager, check whether >Enabled< appears next to “Virtualization” within the “Performance” tab.

The installation of the programming station software generates warnings because Hyper-V hardware virtualization is enabled. What does this mean?2025-04-09T16:30:01+00:00

Third-party virtualization applications, such as ORACLE VirtualBox or VMware Workstation, rely on the Intel VT-x or AMD-V instruction set extensions, which are available on most current processors. However, they are no longer fully available to the virtualization application if Microsoft already uses these instruction set extensions for its own functions, such as Hyper-V, WSL2 and virtualization-based security.

In order to use third-party virtualization software with hardware virtualization, you must deactivate the abovementioned functions on your PC.

Alternatively, when Hyper-V is enabled, the third-party virtualization applications can use a software interface as a replacement for the abovementioned instruction set extensions. This can result in performance losses and limited functionality that has an effect, for example, when the programming station is used in conjunction with VirtualBox. Although this combination is possible, a warning appears both when the programming station software is installed and when it is started. This combination may not be suitable for productive use of the programming station software.

HEIDENHAIN has no influence over which applications are installed on a PC or which Windows features are needed. Please check whether the use of the programming station software, including VirtualBox, is possible on the intended PC.

It is possible to use VMware Workstation as an alternative if enabling Hyper-V is unavoidable on your PC. When VMware Workstation 16 or later is used in conjunction with Windows 10 20H2, it is possible to enable Hyper-V and use VMware Workstation as a virtualizer for the programming station software with only minor performance losses. Not all versions of the programming station software are prepared for installation with VMware Workstation. VMware Workstation is not part of the installation package of the programming station software and must be installed by the user. Please note: It is not possible to install the programming station software in the VMware Workstation Player.

How can I check whether Hyper-V is enabled on my PC?2025-04-09T16:59:47+00:00

  • Enter “System information” into the Windows search field.
  • Open the “System Information” app and scroll all the way down to the bottom.
  • Check whether the following entry is shown: “A hypervisor has been detected. Features required for Hyper-V are not displayed.”

Example: Hyper-V is enabled

Example: Hyper-V is disabled

Hyper-V is enabled on my PC. What options are there for using the programming station software?2025-04-09T17:08:44+00:00

Note the system requirements along with the following information:

  1. HEIDENHAIN has no influence over which applications are installed on a PC or which Windows features are needed. Please check whether the use of the programming station software, including VirtualBox, is possible on the intended PC. Also check which feature uses Hyper-V and whether you can deactivate this feature along with Hyper-V.
  2. As an alternative to VBox, you can install VMware Workstation. If you do this, then the option of using VMware Workstation is offered during the customized installation of the programming station software. Please note: It is not possible to install the programming station software in the VMware Workstation Player!
  3. Test the installation of the programming station software with Hyper-V enabled to see whether it is sufficient for your needs. Although this combination is possible, a warning appears both when the programming station software is installed and when it is started. This combination may not be suitable for productive use of the programming station.
How can I install more than one programming station of the same control on my PC?2025-04-09T17:10:30+00:00

The name of the programming station to be installed is automatically assigned during installation in “Default” mode.

If you wish to install more than one programming station of the same control on a computer, select “Custom” during installation. You can now assign any name to the programming station and thus install multiple programming stations of the same control on your PC.

How can I establish a connection to my programming station?2023-02-19T12:27:45+00:00

Establishing a connection with TNCremo

It is possible to transfer data with the TNCremo program provided by HEIDENHAIN, just as on the real machine.

  1. Download the most current TNCremo version.
  2. Unpack the ZIP file (e.g., WinZip or 7-Zip).
  3. Run Setup.exe, and follow the instructions of the installation wizard.
    • After successful installation, a new TNCremo desktop icon is created.
  4. Start the TNCremo software with the newly created desktop icon.
  5. Establish a new connection via the Connection tab.
    • New configuration
  6. Enter a recognizable name for this connection (e.g., “TNC640 Prog”).
  7. Select the installed programming station to which the connection should be established.
  8. When selecting “Local programming station VirtualBox,” the IP address must be modified in the Settings tab.
    • Determine the address via the Control Panel.
  9. Connection with Connection tab: establish the connection.
    • The screen in TNCremo splits, and the TNC:\ programming station partition is displayed.
Can I run an old programming station on a current version of Windows?2022-11-10T21:16:48+00:00

This cannot be answered across the board and sometimes depends on other factors such as a graphics driver. To find out the operating systems for which the individual versions are released, see the information in the download area.

It is sometimes possible to adapt a current and therefore runnable programming station to the cycle structure of an older version, thus allowing programming errors to be reduced.

As a last option, a Windows XP computer, for example, can be used in a virtual environment in order to install the old programming station.

How can I download programs to and from the programming station?2022-07-13T16:34:00+00:00

We recommend the same procedure as on the real machine:

  1. Connection to a network drive on which all NC programs are saved, and transference via Program Management on the programming station.
  2. Use of TNCremo on this or another PC in the network.

NC programming

Why is the final hole of the bolt hole circle drilled twice?2023-07-20T16:02:00+00:00

This is because Cycles 220 and 221 are DEF-active and do not need to be started separately. If, however, an M99 function or CYCL CALL is programmed, then the machining cycle is run again at the same point at which Cycle 22x ends.

What does “Angle cannot be calculated” mean?2022-07-13T16:45:20+00:00

This message is output by the TNC when no suitable solution can be calculated with the entered values. This could be caused by incorrect or missing sequences (SEQ), a limited traversing range, an incorrect kinematic description, or a missing M138 function on a machine with three rotary axes.

Can I run a Siemens program on a HEIDENHAIN control?2022-07-13T16:45:46+00:00

No, in this case, even ISO programming is specific to the control. The only exceptions are programs that contain only G0 and G1, but the header must also be changed.

What postprocessor does HEIDENHAIN recommend?2022-07-13T16:46:45+00:00

The postprocessor must always be purchased from the CAM system manufacturer. Whether 2D, 3D (inclined machining), or 3D simultaneous machining is required depends on the machine, the NC software, and, of course, on the range of parts to be machined.

How can I copy a tool table to my control?2022-07-27T22:07:07+00:00

If the file was created in the correct format, then it can be copied to the TNC with the extension “.a” via TNCremo or a USB drive. Once on the TNC, it can be copied from the program manager to the active Tool.t via the “Copy” function. It is also possible to “merge” the file directly into the Tool.t via TNCcmd. Both procedures are described in the User’s Manual and may vary slightly depending on the TNC.

How can I edit a tool table on my computer?2022-07-13T16:43:36+00:00

Encoders

Where can I find the signal period of my encoder?2022-08-22T14:16:53+00:00

Our infobase will tell you everything about our products. You can search for your encoder based on your ID number or product name.

Where do I find the “line count” information on my ID label?2022-08-22T14:21:12+00:00

Line count on the ID label

The first number after the model designation is the “line count”.

Take, for example, the ERN 420 1024:

  • Model designation: ERN 420
  • Line count: 1024
What is the difference between EnDat02 and EnDat22?2023-07-03T17:07:47+00:00

The EnDat02 and EnDat22 order designations define different technical parameters that are important for the connection of an encoder. This includes the availability of incremental signals, the typical voltage supply range, the command set, and the maximum clock frequency. Among other things, the following table applies:

Incremental signalVoltage supply rangeCommand setMax. clock frequency
EnDat02With 1 VPP incremental signal3.6 V to 5.25 V

or

3.6 V to 14 V

Command set 2.2≤ 2 MHz  or
≤ 8 MHz  or 16 MHz
EnDat22Without incremental signal3.6 V to 5.25 V

or

3.6 V to 14 V

Command set 2.2≤ 8 MHz  or 16 MHz

Please refer to the interface brochure with its additional information and exceptions noted in the technical data.

For more information about EnDat, please refer to https://endat.heidenhain.com/.

What is the difference between resolution and accuracy?2022-08-22T14:16:48+00:00

Resolution is the smallest-possible measuring step. This means that, the higher the resolution, the more precisely a value can be displayed.
Measuring accuracy is the maximum value by which the encoder may deviate from the correct value.
