The parameter settings for straightness compensation contain an error. Possible causes are as follows: 1. A parameter for a movement axis or compensation axis contains an axis number which is not used. 2. More than 128 pitch error compensation points exist between the negative and positive end points. 3. Compensation point numbers for straightness compensation are not assigned in the correct order. 4. No straightness compensation point exists between the pitch error compensation points at the negative and positive ends. 5. The compensation value for each compensation point is too large or too small.

A G68 command block contains a format error. This alarm is issued in the following cases: 1. I, J, or K is missing from a G68 command block (missing coordinate rotation option). 2. I, J, and K are 0 in a G68 command block. 3. R is missing from a G68 command block.

Three-dimensional coordinate conversion G68 has been specified three or more times.

Blocks containing the G110 codes were successively specified in tool-tip radius compensation for the B-axis.

The machine could not move about the B-axis because parameter No.8250 was incorrectly specified, or because the PMC axis system could not be used.

An attempt was made to execute a program for the B-axis which had not been registered.

More than six M codes for starting movement about the B-axis were specified.

Depth of cut Q was not specified for the G83 code (peck drilling cycle). Alternatively, 0 was specified in Q for the B-axis.

Point R was not specified for the canned cycle for the B-axis.

A feedrate was not specified for cutting feed about the B-axis.
