Check the current axis position and compare against working area limits in MD36100 $MA_POS_LIMIT_PLUS and MD36110 $MA_POS_LIMIT_MINUS for affected axes.

Review the NC program block that triggered the alarm and verify all programmed coordinates are within the permissible working envelope.

Check active protection zones (MD10600-10650) and ensure programmed path does not violate any defined restricted areas.

If limits are correct, modify the NC program to remain within valid working area. If limits need adjustment, verify with machine documentation and modify machine data accordingly.

Changing working area limits requires machine manufacturer authorization and proper safety assessment.

Identify the programmed feedrate (F word) or spindle speed (S word) in the current NC block and compare against MD32000 $MA_MAX_AX_VELO and MD32010 $MA_AX_VELO_LIMIT.

Check if machine is in a restricted mode (DRY RUN, single block with override) which may impose temporary lower limits on velocity.

For spindle speed, verify against MD35100 $MA_GEAR_STEP_MAX_VELO and MD35110 $MA_GEAR_STEP_MIN_VELO for the current gear stage.

Correct the NC program to use feedrates and speeds within permissible limits, or review machine data if limits are incorrectly configured.

Review the motion block geometry for extremely short segments or sharp angle transitions that require excessive acceleration.

Check MD32300 $MA_MAX_AX_ACCEL and MD32310 $MA_AX_ACCEL_LIMIT to verify acceleration limits are appropriate for the programmed motion.

Examine jerk settings in MD32431 $MA_MAX_AX_JERK if dynamic response is limited and causing the alarm during high-speed contouring.

Optimize NC program by smoothing toolpath transitions, increasing segment length, or reducing feedrate in critical areas where dynamic limits are reached.
