230-01BF

Access axis configuration menu

Navigate to MOD function -> System Parameters -> Axes -> PhysicalAxes -> CfgAxis and note the axisHw setting for the affected axis.

Document current settings before making changes for rollback purposes

Check encoder type configuration

Go to Axes -> ParameterSets -> CfgAxisHardware -> posEncoderType and verify the encoder connection type matches the axisHw configuration.

Incorrect encoder configuration can cause axis runaway - ensure machine is in safe state

Correct configuration mismatch

Set posEncoderType to match axisHw: for CC422/CC424/CC520 use encoder connected to CC, for AnalogMC/DisplayMC/ManualMC use encoder connected to MC.

Use TNCremo for remote parameter editing to avoid machine downtime

Restart control and verify

Perform control restart and check that alarm 230-01BF clears, then test axis movement in manual mode.

Always perform reference point return after encoder configuration changes

Verify installed hardware modules

Check PLC -> System Info -> Hardware to identify actual installed modules (MC, CC cards) and compare with axisHw configuration.

Use diagnostic screen to see real-time hardware status and module recognition

Check encoder cable connections

Physically verify encoder cables are connected to the correct module (MC or CC) as specified by the axisHw parameter.

Power down control before checking encoder connections to prevent damage

Reconfigure axisHw parameter

In MOD -> System Parameters -> Axes -> PhysicalAxes -> CfgAxis, change axisHw to match actual hardware installation (e.g., InOutCC for CC cards, AnalogMC for MC connection).

Consult machine electrical drawings to verify intended encoder connection scheme

Update encoder type accordingly

Adjust posEncoderType in CfgAxisHardware to match the corrected axisHw setting and restart control.

Ensure encoder scaling and direction parameters remain correct after hardware changes

Verify ProfiNet axis configuration

Check if axisHw is set to ProfiNet in Axes -> PhysicalAxes -> CfgAxis for the affected axis.

ProfiNet axes require additional network configuration parameters

Check ProfiNet encoder settings

Navigate to CfgAxisHardware and ensure posEncoderType specifies ProfiNet connection rather than MC or CC connection.

ProfiNet encoder timing is critical - verify network cycle times are appropriate

Validate ProfiNet network status

Check PLC -> ProfiNet status to ensure the encoder device is properly connected and communicating on the network.

Use ProfiNet diagnostic tools to verify encoder data transmission quality

Configure ProfiNet encoder parameters

Set all encoder-related parameters to ProfiNet connection type and verify network device addressing matches physical installation.

ProfiNet configuration errors can affect multiple axes - verify other axis configurations

Check parameter consistency

Use MOD -> System Parameters -> Check Parameters function to identify any configuration inconsistencies or corrupted values.

Save current parameters before attempting any corrections

Compare with backup configuration

Load known good parameter backup and compare encoder and axis hardware settings with current configuration.

Ensure backup is from compatible TNC software version before restoring

Restore correct configuration

Either manually correct the mismatched parameters or restore from verified backup, ensuring axisHw and posEncoderType alignment.

Use parameter comparison tools to identify only the affected parameters
