Access spindle configuration parameters

Navigate to MOD → Machine Parameters → Spindle Parameters → P3xxx series for the affected spindle number.

Use parameter search function (CTRL+F) to quickly locate spindle-specific parameters

Check fast input assignment

Verify parameters P3041 (spindle encoder input) and P3042 (spindle speed input) are not assigned to standard PLC I/O addresses but to HSCI channels.

Document current settings before making changes

Reassign to HSCI-PL interface

Change the input assignment from standard I/O (e.g., X1.1) to proper HSCI format (e.g., HSCI1.ENC1) in the spindle parameter block.

HSCI addresses typically follow format HSCIx.ENCy where x is interface number and y is encoder channel

Validate configuration and restart

Save parameters, perform PLC restart (MOD → PLC → Restart), and verify alarm clears during spindle initialization.

Access PLC configuration

Open PLC program editor via MOD → PLC → Edit and examine the I/O assignment table for spindle-related inputs.

Ensure you have backup of PLC program before modifications

Identify bus system assignment

Check if spindle fast inputs are assigned to fieldbus addresses (e.g., PROFIBUS: P1.x or EtherCAT: E1.x) instead of local/HSCI addresses.

Fast inputs must have response times under 1ms - only HSCI-PL and internal PL meet this requirement

Reconfigure input mapping

Modify PLC I/O configuration to map spindle fast inputs to HSCI-PL channels or internal PL addresses in the hardware configuration.

Use TNCopt or machine manufacturer's configuration tool for proper HSCI setup

Compile and download PLC program

Compile the modified PLC program, download to TNC, and perform complete system restart to activate new I/O mapping.

Verify HSCI hardware recognition

Check MOD → System Info → Hardware to confirm HSCI-PL card is detected and shows 'OK' status with proper firmware version.

HSCI-PL cards require specific firmware versions compatible with your TNC software release

Check HSCI configuration parameters

Verify parameters P0180-P0189 (HSCI interface configuration) are properly set for your specific HSCI-PL hardware variant.

Incorrect HSCI parameters can cause hardware damage - consult machine documentation

Validate cable connections

Inspect HSCI-PL cable connections at both TNC and spindle encoder ends, ensuring proper shielding and secure connections.

Use oscilloscope to verify differential encoder signals if available - should show clean square waves

Reinitialize HSCI interface

Perform HSCI reset via MOD → Diagnosis → HSCI → Reset Interface, then restart TNC to reinitialize hardware recognition.

Compare with backup parameters

Access MOD → Data Management → Machine Parameters and compare current spindle parameters with known good backup from TNC:\system\par\backup folder.

TNC automatically creates parameter backups during software updates - check timestamps

Verify parameter version compatibility

Check parameter header information for version compatibility with current TNC software version in MOD → System Info → Software.

Loading incompatible parameters can cause system instability

Reset spindle-specific parameters

Reset only spindle-related parameters (P3000-P3999 series) to default values, then reconfigure according to machine specifications.

Use parameter reset function for specific ranges rather than full system reset to preserve other settings

Reconfigure from machine documentation

Systematically reconfigure spindle parameters using machine manufacturer's parameter list, ensuring fast inputs are properly assigned to HSCI-PL.
