Access Manual Operation Mode

Press the Manual Operation key and navigate to the axis reference menu to identify which axes are being processed.

Check the axis status display to see which axes are currently active in the homing sequence.

Separate axis group homing

Home axes sequentially by group - first complete all main machine axes (X,Y,Z), then proceed with auxiliary or spindle axes separately.

Never attempt to home spindle and linear axes simultaneously as they operate in different control loops.

Verify axis group parameters

Check machine parameter MP7500 (axis assignment) to confirm proper axis group configuration and ensure no conflicts exist.

Document the axis group assignments for future reference and troubleshooting.

Enter machine parameter mode

Access MOD function, enter code 123, and navigate to machine parameters MP7500 series for axis group assignments.

Only modify machine parameters with proper authorization and backup existing settings first.

Review axis group configuration

Examine MP7500 (1st axis group), MP7501 (2nd axis group), etc., to ensure each axis is assigned to only one group and assignments match machine configuration.

Standard configuration: MP7500=1-3 for X,Y,Z axes, MP7501=4 for spindle axis.

Correct parameter conflicts

Modify conflicting parameters to ensure proper axis group separation, save parameters, and perform a control restart to activate changes.

Incorrect axis group parameters can cause serious machine malfunctions - verify with machine documentation before changes.

Access PLC diagnostics

Navigate to PLC menu via MOD function and examine the current PLC program execution to identify axis checking routines.

Look for markers M4000-M4999 which typically control axis reference and checking functions.

Review PLC axis reference logic

Examine PLC modules handling axis reference (typically modules 9xxx) to identify simultaneous axis group checking commands.

PLC modifications require specialized knowledge - document all findings before making changes.

Modify PLC sequence timing

Adjust PLC logic to sequence axis group checking operations with appropriate delays between different groups using timer functions.

Use T-type timers with 2-3 second delays between axis group operations for reliable sequencing.

Check channel configuration

Review machine parameter MP20000 series to verify channel-specific axis assignments and ensure no overlap between channels for different axis groups.

Each axis should be assigned to only one channel to prevent conflicts during checking operations.

Verify channel synchronization

Examine MP20100 (channel synchronization) settings to ensure proper coordination between channels during axis operations.

Improper channel synchronization can cause axis collisions in multi-channel systems.

Adjust channel axis allocation

Modify channel parameters to properly segregate axis groups between channels, ensuring each channel operates within its designated axis group boundaries.

Use channel 1 for main machining axes and channel 2 for auxiliary operations to maintain clear separation.

Access servo parameter menu

Navigate to the servo parameter display and check parameters P-AXIS-00-00 through P-AXIS-xx-00 for proper axis group identification.

Servo parameter changes can affect machine safety systems - proceed with extreme caution.

Verify axis group consistency

Compare servo amplifier axis group settings with machine parameters to ensure consistent axis group assignments throughout the system.

Use the parameter comparison function to quickly identify discrepancies between different parameter sets.

Synchronize parameter settings

Update servo parameters to match machine parameter axis group assignments and perform a complete system restart to ensure synchronization.

Always backup servo parameters before making changes as incorrect settings can damage servo amplifiers.
