What causes Okuma OSP alarm 1778?

Dummy tool not mounted in the ATC turret station required for the commanded move. Program commands an axis move without the correct dummy tool (L-tool or M-tool) in place. Operator removed the dummy tool during setup and did not reinstall it.

How do I fix Okuma OSP alarm 1778?

1. Read the code number shown with the alarm: code 1 = No dummy tool set for either the L-tool or the M-tool position; code 2 = The L-tool dummy tool is not set; code 3 = The M-tool dummy tool is not set 2. Read the code on screen: Code 1 means no dummy tool for either L-tool or M-tool, Code 2 means the L-tool dummy is missing, Code 3 means the M-tool dummy is missing. 3. Mount the required dummy tool in the ATC turret station indicated by the code, then re-command the axis move. 4. Check the program and setup sheet to confirm which dummy tool (L or M) the operation expects at that turret position. 5. For a test run where no tools are actually used, this check can be disabled per the manual's note for test operation; re-enable it before production.

Alarm 1778

Okuma OSP Alarm A 1778 - No dummy tool in ATC turret

An axis move was commanded while the ATC turret position that should hold a dummy tool is empty. The control blocks the move because a real tool in that station could collide with the machine during axis travel. This is a programming or setup issue, not a hardware failure.
