Access Machine Parameters

Press MOD key, select 'Machine parameters' from the TNC menu, navigate to spindle parameters section.

Ensure machine is in a safe state before accessing machine parameters.

Check MP7160 Value

Locate MP7160 (Tool selection mode) and verify it has a valid value (typically 1-4 depending on tool changer type).

Common values: 1=random tool changer, 2=chain magazine, 3=disk magazine, 4=manual tool change.

Set Correct Parameter Value

Enter the appropriate value for your tool changer configuration and confirm the change.

Incorrect values may cause tool changer malfunction - consult machine documentation.

Restart Control

Perform a control restart (CTRL+ALT+DEL) to activate the new parameter setting.

Access Configuration Manager

Navigate to MOD > Configuration > Spindle configuration to check current spindle setup.

Look for any red error indicators or missing parameter fields in the configuration display.

Backup Current Configuration

Create a backup of current configuration files before making changes using the TNC file manager.

Always backup configurations before restoration attempts.

Restore Default Configuration

Load the default spindle configuration template and reconfigure tool selection parameters according to machine specifications.

Default configurations are typically stored in TNC:\system\config\templates.

Validate Configuration

Test the configuration by attempting a tool change operation in MDI mode using M6 command.

Access PLC Programming

Enter PLC programming mode via MOD > PLC > Programming to examine tool change logic.

PLC modifications require advanced knowledge - document all changes.

Check Tool Selection Markers

Verify PLC markers M4xxx series (tool change markers) are properly defined and initialized in the PLC program.

Common tool selection markers: M4000-M4099 for tool changer status and mode selection.

Validate Parameter Transfer

Check that MP7160 value is properly transferred to PLC variables using V.P.MP7160 syntax in PLC code.

Use PLC status display to monitor real-time parameter values during operation.

Test PLC Logic

Use PLC test mode to step through tool selection logic and verify proper parameter handling.

Check Hardware Connections

Verify all cables between TNC and tool changer interface are secure and undamaged.

Power down machine before checking electrical connections.

Test I/O Signals

Use PLC status display to monitor tool changer I/O signals and verify proper communication.

Tool changer ready signal should be active before attempting parameter validation.

Reset Communication Interface

Cycle power to tool changer interface module and perform communication reset via PLC program.

Some interfaces require specific reset sequences - check interface documentation.

Verify Interface Parameters

Check interface-specific machine parameters (MP7xxx series) for correct hardware configuration.
