HEIDENHAIN 230-04C6 - Brake: MP_connection must not be configured

Brake: MP_connection must not be configured

The CfgBrake/connection parameter is not supported by the current machine configuration.

Root Cause Summary

Alarm 230-04C6 occurs when the machine parameter CfgBrake/connection is configured for a brake system that is not supported by the current TNC hardware configuration. This typically happens when brake parameters are set for axes that don't have brake hardware installed or when the drive system doesn't support the configured brake connection type.

Safety

  • Refer to Heidenhain service manual
  • Ensure qualified technician performs repairs

Causes and Fixes

  1. 1

    Access machine parameter menu

    Navigate to MOD > Machine Parameters > CfgAxes to view axis configuration parameters.

    Use the search function (CTRL+F) to quickly locate brake-related parameters

  2. 2

    Check brake configuration

    Locate CfgBrake/connection parameter for the affected axis and verify if brake hardware is actually installed on this axis.

    Do not modify parameters without proper documentation of original values

  3. 3

    Disable brake parameter

    If no brake hardware exists, set CfgBrake/connection to 'not configured' or delete the parameter entry entirely.

    Check the machine documentation to confirm which axes should have brake systems

  4. 4

    Restart control system

    Perform a complete TNC restart to reload machine parameters and clear the alarm condition.

DIY Feasiblehigh confidence

Call a technician if:

  • ·Hardware brake installation required
  • ·Drive system replacement needed
  • ·Multiple parameter corruption detected

Prevention

  • Always backup parameters before modifications
  • Verify hardware compatibility before parameter changes
  • Keep parameter documentation updated
  • Use parameter validation tools

Common Mistakes

  • Configuring brakes for axes without hardware
  • Copying parameters between different machine types
  • Not verifying drive system compatibility
  • Skipping parameter validation after changes
