Access IOCP configuration

Navigate to MOD function → System Parameters → IOCP to examine the current I/O configuration file.

Always backup the current IOCP before making changes

Locate axis brake configuration

Search for the axis number shown in %2 and verify if brake output signals (typically BRK+ and BRK-) are assigned to physical outputs.

Ensure machine is in safe state before modifying I/O assignments

Add missing brake outputs

Assign appropriate digital outputs for brake control using the IOCP editor, typically assigning BRK signals to available DO channels.

Validate and reload IOCP

Save the IOCP file, perform syntax check, and reload the configuration through PLC → Reload IOCP.

Verify IOCP file version

Check the IOCP file date and version in MOD → System Info → IOCP Info to confirm it matches the machine configuration documentation.

Locate correct IOCP backup

Search TNC:\system\iocp\ directory for backup IOCP files or retrieve the correct version from machine documentation.

Load correct IOCP file

Navigate to MOD → System Parameters → Load IOCP and select the appropriate configuration file for your machine setup.

Restart control system

Perform a complete TNC restart to ensure all I/O assignments are properly initialized with the new IOCP configuration.

Check brake module connections

Verify all connections to the brake control module, including power supply, communication cables, and brake output wiring.

Turn off main power before checking electrical connections

Verify module status LEDs

Examine status indicators on the brake control module for error conditions, communication faults, or power supply issues.

Test brake outputs manually

Use PLC → Manual Operation → Digital Outputs to manually activate the brake control outputs and verify proper operation.

Check system diagnostics

Review MOD → Diagnostics → I/O Status for any communication errors or missing modules in the system configuration.

Check axis brake parameters

Navigate to MOD → Machine Parameters and examine MP73xx series for the affected axis to verify brake enable settings.

Focus on parameters MP7380-MP7389 which control brake timing and operation

Verify brake requirement settings

Check if brake functionality is enabled in machine parameters but not supported by current IOCP configuration.

Align parameters with IOCP

Either disable brake requirements in machine parameters if not needed, or add proper brake I/O assignments to IOCP file.

Test brake operation

After configuration changes, test brake engagement/disengagement through axis movement commands to verify proper operation.
