Type of error: B — Registered data (the program or tool data includes an error) Stopped status: I — Reset stop Clearing procedure: O — Eliminate cause -> press reset key Display colour: Red On-screen parameters (shown in parentheses): WNo., UNo. Cause: 1. A corner-face unit or plane inclination measurement has been designated in unit data other than inclined-plane machining unit data. 2.

Calibration measurement has been designated for the top plane or an inclined plane. 4. Groove center, hole center, boss center, and step width measurements have been designated for an inclined plane. Action: 1. A corner-face unit and plane inclination measurement can be designated only for an inclined plane. 2. Table rotational machining can be executed only for the top plane. 3. Calibration measurement is possible only for the side. 4. Only reference plane measurement and plane inclination measurement are possible for inclined planes.
