103014

Check the alarm message text to identify which specific axis requires referencing (typically displays axis name like X, Y, Z, etc.).

Press the 'REF POINT' softkey or select the reference point menu in the JOG mode of the machine control panel.

Select all axes that need referencing and press NC START to execute the reference point cycle. Observe axis movement to reference position.

Ensure work area is clear and no obstacles prevent axis travel to reference switches.

Verify all required axes show the reference point indicator (green 'R' symbol) on the position display before restarting program.

Check the alarm log for preceding alarms related to encoder faults, amplifier errors, or position monitoring alarms that occurred before the 103014.

Verify encoder cables and connections are secure at motor, amplifier, and NCU. Check for damage or contamination.

Disconnect main power before checking electrical connections.

Review whether an emergency stop or RESET was activated during operation which may have cleared the reference status.

After resolving any hardware issues, perform complete reference point cycle for all axes and verify stable reference status.

Access machine data and verify MD34100 $MA_REFPOINT_SYNC_LOCK and MD34200 $MA_ENC_REFP_MODE settings for the affected axis match machine manufacturer specifications.

Only modify machine data if you have backup and manufacturer documentation. Incorrect changes can damage machine.

Check MD30200 $MA_IS_ROT_AX setting to ensure rotary vs linear axis configuration is correct for the affected axis.

Verify MD34010 $MA_REFP_CAM_DIR_IS_MINUS reference point approach direction is correctly set for reference switch location.

After any machine data changes, perform PLC reset and NCK reset, then execute complete reference point cycle and test program execution.

Machine data changes require control restart and may affect machine behavior.
