Access brake configuration

Navigate to MOD function → Machine Parameters → CfgBrake section to view current brake configuration parameters.

Use Ctrl+F to quickly search for 'CfgBrake' in the parameter list

Verify MP_connection value

Check the MP_connection parameter value against the available I/O connections in your system documentation. Valid values typically range from 0-15 depending on PLC configuration.

Never change brake parameters without proper safety lockout procedures

Correct parameter value

Set MP_connection to the correct I/O connection number as specified in your machine's electrical documentation.

Cross-reference with PLC I/O assignment list to ensure correct mapping

Restart control

Perform a complete TNC restart to activate the new brake configuration parameters.

Check I/O diagnostics

Navigate to MOD → Diagnosis → I/O to verify the status of the configured brake I/O connection.

Look for red indicators showing missing or faulted I/O modules

Verify physical connections

Inspect the physical I/O module connections and cables for the brake circuit, checking for loose connections or damaged cables.

Ensure machine power is locked out before inspecting electrical connections

Test I/O functionality

Use the TNC I/O test function to manually activate the brake output and verify proper operation.

Monitor actual brake engagement/disengagement during I/O testing

Replace faulty hardware

Replace any identified faulty I/O modules or repair damaged wiring as needed.

Review PLC brake logic

Access the PLC program and locate the brake control logic to identify the correct I/O assignments and connection numbers.

Search for 'BRAKE' or 'BRK' symbols in the PLC program for quick location

Compare TNC and PLC settings

Cross-reference the CfgBrake/MP_connection value with the PLC brake I/O assignments to identify mismatches.

Document all current settings before making changes

Synchronize configurations

Update either the TNC brake parameters or PLC program to ensure consistent brake connection assignments.

Coordinate with machine builder documentation for original configuration

Test brake operation

Perform a complete brake function test including emergency stop and axis hold scenarios.

Backup current configuration

Create a backup of the current machine parameters using MOD → Data Management → Export function.

Always backup before attempting configuration restoration

Restore from backup

Load a known good configuration backup that contains correct brake parameters from MOD → Data Management → Import.

Use the most recent backup that had working brake functionality

Verify parameter integrity

Check all CfgBrake parameters for proper values and consistency with machine documentation.

Compare with identical machines if available for reference

Perform system validation

Run complete brake system tests including all axes and emergency scenarios to confirm proper operation.
