Access machine parameter menu

Press MOD key, select 'Machine Parameters', navigate to MP1000-1099 servo parameters for the affected axis.

Use Ctrl+F to quickly search for specific parameter numbers

Verify mandatory servo parameters

Check MP1020 (servo lag limit), MP1030 (Kv factor), MP1040 (acceleration), and MP1050 (max velocity) are present and have valid values.

Never modify servo parameters without proper documentation

Restore missing parameters

If parameters are missing, restore from backup .PLC file or contact machine builder for original parameter values.

Always create parameter backup before making changes using TNCremo software

Perform parameter reset

Execute 'Reset Machine Parameters' from MOD menu and restart control to reinitialize servo configuration.

Check axis definition parameters

Navigate to MP100-199 and verify MP110 (axis name), MP120 (axis type), and MP130 (reference system) are configured for the affected axis.

Use parameter search function to quickly locate axis-specific parameters

Verify encoder configuration

Check MP140-149 encoder parameters including MP140 (encoder type), MP141 (resolution), and MP142 (encoder monitoring) are present.

Incorrect encoder parameters can damage the drive system

Validate reference point setup

Ensure MP130-139 reference point parameters are complete, including reference cam direction and reference point offset values.

Reload axis configuration

Save parameters and perform control restart to reload complete axis configuration data.

Verify parameter file integrity

Check the restored .PLC parameter file size and compare with known good backup to identify potential corruption.

Always verify file checksums when transferring parameter files

Restore from alternate backup

Load parameters from a different known-good backup file using TNCremo or direct file transfer to TNC:/system/.

Ensure backup compatibility with current TNC software version

Perform selective parameter import

Use TNCremo to selectively import only the missing parameter ranges rather than complete file restore.

Validate parameter completeness

Cross-reference imported parameters against machine documentation to ensure all required parameters are present and valid.

Check drive interface parameters

Navigate to MP7000+ range and verify drive type, communication protocol, and interface parameters are configured for each axis.

Drive parameters are often grouped by axis number (e.g., MP7100 for X-axis, MP7200 for Y-axis)

Verify EnDat/SSI encoder setup

Check MP7xxx encoder interface parameters match the installed encoder type and wiring configuration.

Restore drive parameters

Import missing drive parameters from machine builder documentation or previous working configuration backup.

Test drive communication

Use TNC diagnostic functions to verify proper communication between control and servo drives after parameter restoration.
