Check axis movement manually

With machine in MANUAL mode and drives OFF, manually move the affected axis to check for binding, rough spots, or obstructions.

Ensure all safety procedures are followed and machine is properly locked out

Inspect mechanical components

Examine ballscrews, linear guides, way covers, and coupling connections for damage, debris, or excessive wear on the affected axis.

Look for metal chips, coolant buildup, or damaged way covers that could cause binding

Verify lubrication system

Check automatic lubrication system operation and verify proper oil/grease distribution to axis components through MOD 114 lubrication menu.

Manual lubrication cycle can be triggered from Setup->Machine->Lubrication menu

Test axis movement

After clearing obstruction, test axis movement in JOG mode at reduced feedrate to verify smooth operation before returning to automatic mode.

Check drive status LEDs

Examine servo amplifier status indicators and verify all power supply voltages are within specification using TNC diagnostic screens.

Access drive diagnostics through MOD 127 or Setup->Diagnosis->Drive menu

Monitor current consumption

Use TNC position monitoring (MOD 214) to observe actual vs. commanded current during axis movement to identify drive performance issues.

High current consumption may indicate mechanical binding or drive problems

Verify encoder feedback

Check encoder signals and position feedback through Setup->Diagnosis->Position menu to ensure proper communication between drive and TNC.

Compare encoder position with machine position display for discrepancies

Test drive parameters

Verify servo loop parameters in CfgAxis configuration match drive specifications and perform servo optimization if necessary.

Check encoder connections

Inspect encoder cable connections at both motor and TNC ends for loose connections, damaged pins, or contamination.

Power down system before disconnecting encoder cables to prevent damage

Monitor encoder signals

Use Setup->Diagnosis->Encoder menu to observe encoder signal quality, including amplitude and phase relationships of A/B channels.

Look for signal dropouts, noise, or amplitude variations that indicate encoder problems

Test reference point procedure

Perform reference point approach (Setup->Reference Point) to verify encoder index pulse and reference switch operation.

Multiple reference point cycles should return to identical positions within encoder resolution

Check for electromagnetic interference

Verify encoder cable routing away from power cables and check for proper shielding and grounding of encoder system.

Perform backlash measurement

Use TNC backlash compensation test in Setup->Machine->Backlash menu to measure actual backlash versus configured values.

Compare measurements at multiple positions along axis travel to identify wear patterns

Check ballscrew end play

Manually check ballscrew end bearings for excessive play or wear that could cause position instability.

Support axis weight properly when checking mechanical components

Inspect coupling connections

Examine motor-to-ballscrew coupling for wear, looseness, or damage that could cause lost motion during direction changes.

Look for witness marks or fretting on coupling surfaces indicating movement

Update compensation parameters

If wear is within acceptable limits, update backlash compensation values in CfgAxis->backlashCompensation parameters to account for measured wear.
