PS007

Access EDIT mode and display the active program. Press RESET to clear the alarm and note the line number shown on the alarm history screen (ALARM > HISTORY).

Search the flagged program block for decimal points after N, O, G, M, T, H, D, S, or P addresses. Common errors include 'G01.' instead of 'G01' or 'M03.0' instead of 'M03'.

Check parameter 3450 bit 0 (MCD) which affects decimal point input interpretation. If set to 1, verify program decimal usage matches pocket calculator format requirements.

Correct the program by removing the decimal point from integer address codes. Re-verify program syntax using SEARCH > CHECK or background edit check if equipped.

Review the program block displayed when alarm occurred. Carefully examine all numeric values for double decimals such as 'X123..45' or 'F10.0.5'.

Check parameter 0000 bit 0 (DPI) decimal point input setting. If DPI=0, trailing zeros may cause confusion; if DPI=1, verify each axis word has maximum one decimal point per parameter 1004-1007 (input increment settings).

Use MDI mode to test suspected command independently. Enter simplified version of the word to confirm decimal point interpretation is correct per system settings.

Correct program by removing duplicate decimal points. If using DNC or drip-feed, verify communications software is not inserting extra characters during transmission.

Navigate to SYSTEM > PARAM and check parameter 1004 (X-axis), 1005 (Y-axis), 1006 (Z-axis), 1007 (4th axis) least input increment values. Also verify parameter 0000 bit 0 (DPI) setting.

Parameter write enable (PWE) must be set via SYSTEM > SETTING parameter 8000 or key switch position before viewing write-protected parameters.

Verify parameter 3450 bit 0 and bit 1 settings for decimal point input type (0=trailing zero suppression, 1=pocket calculator type). Ensure program format matches the configured input method.

Check if feedrate (F) or spindle speed (S) commands contain decimal points incompatible with parameters 1420 (F-code decimal point), 3701 (S-code input type). Review alarm line for F/S code formatting.

Modify program to match parameter-defined input format, or coordinate with machine builder to adjust parameters 0000, 1004-1007, 1420, 3450, 3701 if decimal point usage is required by application.

Changing input increment parameters affects all program coordinates system-wide and may require program conversion. Backup all programs before parameter modification.
