Código 971: CANNOT USE TOOL TIP PT CONTROL

Type of error: B — Registered data (the program or tool data includes an error) Stopped status: J — Single-block stop Clearing procedure: P — Press reset key Display colour: Red On-screen parameters (shown in parentheses): WNo., NNo., BNo. Cause: 1. A command of tool tip point control is given under incompatible modal conditions. 2. A G43.5 command is given in spite of the selection of the workpiece coordinate system for programming. 3. Under selection of the G-code system for turning machines, a command of tool tip point control is given with the parameter setting “F161 bit 1 = 0 (Geometric offset by logically shifting the coordinate system).” 4. A command of circular interpolation is given under the mode of G43.5 or with the table coordinate system selected for programming. Action: 1. Check the current modal conditions and cancel the unsuitable mode. 2. Use the other preparatory function G43.4, or select the table coordinate system for programming. 3. Set F161 bit 1 to “1” (Geometric offset by physically shifting the tool). 4. To use circular interpolation, give a G43.4 command, or select the workpiece coordinate system for programming.
