What causes Okuma OSP alarm 1737?

Program error: G00 block missing the required M203 command. MDI command error: G00 entered without M203. M203 designated in a block where special motor brake control forbids it (code 1).

How do I fix Okuma OSP alarm 1737?

1. Read the code number shown with the alarm: code None = M203 command was not designated in the block containing G00; code 1 = M203 was designated while special motor brake control applies, where it is not permitted 2. Read the code: no code means the G00 block lacked M203; code 1 means M203 was designated under special motor brake control where it must not be used. 3. Locate the offending block in the program (or the last MDI line) and check whether the G00 move includes M203. 4. Correct the program following the manual's pattern, e.g. pair the rapid move with M203 in the same block: 'G00 X500 Z800 M203' before the next positioning/tool block. 5. For code 1, remove the M203 designation from the block controlled by the special motor brake control. 6. Re-run from a safe point and confirm the turret clamps/unclamps correctly through the corrected blocks.
