The maximum cutting feedrate (parameter No. 1422, No. 1430, No.

Function category:
High–precision contour control
Alarm details:
G05 P10000 has been specified in a mode from which the system can­not enter HPCC mode.

G05P0 has been specified in G41/G42 mode or with offset remaining.

The specified rotation axis does not exist for tool axis direction handle
feed.

M codes which belonged to the same group were specified in a block.
Alternatively ,an M code which must be specified without other M codes
in the block was specified in a block with other M codes.

Function category:
Polygon turning
Alarm details:
In G51.2 mode, the speed of the spindle or polygon synchronous axis
either exceeds the clamp value or is too small. The specified rotation
speed ratio thus cannot be maintained.

A parameter for program restart is invalid.
The end command (G110) was specified before the registratioin start

command (G101, G102, or G103) was specified for the B–axis.
While a registration start command (G101, G102, or G103) was being

executed, another registration start command was specified for the B–
axis.

While the machine was moving about the B–axis, at attempt was made
to register another move command.

Commands for movement about the B–axis were not registered be­cause of insufficient program memory.

Multiple movements were specified with the G1 10 code for the B–axis.

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

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

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

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

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

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.

Blocks containing the G1 10 codes were successively specified in tool–
tip radius compensation for the B–axis.

For example, in three–dimensional tool compensation mode using an
