1016

Press the RESET button on the operator panel to clear alarm 1016.

Navigate to MDI mode on the mode selector switch and review the command displayed on the MDI input screen.

Re-enter the MDI command ensuring a semicolon (;) is placed at the end of the block. Example: G00 X100.0 Z50.0; or M03 S1000;

Press INPUT or INSERT key followed by CYCLE START to execute the properly formatted command.

Press RESET to clear the alarm, then navigate to the MDI screen and use the DELETE or CLEAR key to completely remove the current MDI buffer contents.

Check Parameter 3107 (MDI input display format) to verify proper character display settings. Default is typically 0 for standard ASCII display.

Manually re-type the entire MDI command character-by-character, avoiding copy-paste operations, and ensure semicolon is added at the end.

If issue persists, inspect MDI keyboard membrane for damaged keys. Navigate to SYSTEM > DIAGNOSIS > 300-series to check for keyboard input diagnostics if available on your control series.

Worn or damaged MDI panel keys may require replacement by qualified service personnel.

Press RESET to clear alarm 1016, then navigate to SYSTEM > PARAM > search for Parameter 3204 (EOB code setting).

Parameter modification requires parameter write enable (PWE) switch ON and parameter lock bit cleared. Unauthorized parameter changes can cause serious machine malfunction.

Verify Parameter 3204 is set to 59 (decimal), which corresponds to ASCII semicolon (;). If different, record the current value before changing.

If modification needed, enable parameter write (set Parameter 3202 bit 0 = 0 or use PWE switch), change Parameter 3204 to 59, then power cycle the control to activate the change.

Power cycle required after parameter modification. Ensure machine is in safe state before shutdown.

After restart, test MDI input with simple command such as G00 X0; to verify proper EOB recognition.
