Access machine data parameters

Navigate to Commissioning > Machine data > Channel data > Working area limitations and check MD36100 $MN_WORKAREA_MINUS_ENABLE and MD36110 $MN_WORKAREA_PLUS_ENABLE settings.

Always backup machine data before making changes using Archive > Machine data

Verify working area limits

Check MD36200-36250 $MN_WORKAREA_MINUS_LIMIT and MD36300-36350 $MN_WORKAREA_PLUS_LIMIT values against actual machine travel limits from manufacturer specifications.

Incorrect limits can cause crashes - verify with machine drawings

Validate coordinate system settings

Verify MD36000 $MN_WORKAREA_CS_SYSTEM coordinate system reference matches your machine setup (machine coordinate system vs. workpiece coordinate system).

Reset and test

Perform NCK reset and test with known good coordinates within the corrected working area limits.

Check channel group configuration

Navigate to Commissioning > Machine data > General machine data and verify MD20100 $MC_AXCONF_MACHAX_USED and MD20110 $MC_AXCONF_CHANAX_NAME_TAB settings.

Use HMI Service > Diagnosis > Machine data to view current active settings

Verify axis assignment

Check MD20070 $MC_AXCONF_GEOAX_ASSIGN_TAB to ensure geometric axes are properly assigned to the correct channel group.

Validate channel data consistency

Cross-reference channel-specific machine data MD30xxx parameters with the channel group assignments to ensure no conflicts exist.

Check active transformations

In the NC program, verify any active TRANSMIT, TRACYL, or TRAORI commands and their parameters against machine data MD24xxx transformation settings.

Disable transformations temporarily to isolate the issue

Verify transformation machine data

Check MD24100 $MC_TRAFO_TYPE_x and related transformation parameters in Commissioning > Machine data > Channel data > Transformations.

Test without transformation

Run the program with transformations disabled (TRAFOOF) to confirm coordinates are valid in basic coordinate system.

Check reference point offsets

Navigate to Machine > Reference point and verify all axis reference point positions match the machine's actual reference point locations.

Verify preset values

Check Offset > Preset values to ensure no incorrect preset offsets are shifting the coordinate system outside working area limits.

Use Machine > Actual position display to monitor real-time coordinate values

Recalibrate if necessary

If reference points are incorrect, perform reference point approach sequence and verify against machine data MD34200 $MA_REFP_SET_POS settings.

Compare software and hardware limits

Check MD36xxx working area limits against MD36600-36650 $MA_POS_LIMIT_MINUS and MD36700-36750 $MA_POS_LIMIT_PLUS hardware limit settings.

Test hardware limit switches

Use Diagnosis > Drive diagnosis > Digital inputs to verify hardware limit switch functionality and positions.

Never bypass hardware limits - adjust software limits instead

Adjust software limits

Modify working area limits to be within hardware limits with appropriate safety margins (typically 1-5mm depending on machine).
