Number ContentsMessage
4508 ILLEGAL COMMAND IN RADIUS In a radius (G88) command, the traveling pitch (Q) or radius (I) was set
to zero or a negative value, or the traveling pitch (Q) was greater than
or equal to the arc length. Alternatively, I, J, K, P, or Q was not specified.
4509 ILLEGAL COMMAND IN CUT AT
ANGLE
In a cut-at-angle (G89) command, the traveling pitch (Q) was set to zero,
negative value, or another value larger than or equal to the length (I).
Alternatively, I, J, P, or Q was not specified.
4520 T, M INHIBITED IN
NIBBLING-MODE
T code, M code, G04, G70 or G75 was specified in the nibbling mode.
4521 EXCESS NIBBLING MOVEMENT
(X, Y)
In the nibbling mode, the X-axis or Y-axis traveling distance was larger
than or equal to the limit (No. 16188 to 16193).
4522 EXCESS NIBBLING MOVEMENT
(C)
In the circular nibbling (G68) or usual nibbling mode, the C-axis traveling
distance was larger than or equal to the limit (No. 16194).
4523 ILLEGAL COMMAND IN
CIRCLE-NIBBL
In a circular nibbling (G68) command, the traveling pitch (Q) was set to
zero, a negative value, or a value larger than or equal to the limit (No.
16186, 16187), or the radius (I) was set to zero or a negative value. Al-
ternatively, I, J, K, P, or Q was not specified.

4530 A/B MACRO NUMBER ERROR The number for storing and calling by an A or B macro was set to a value
beyond the range from 1 to 5.
4531 U/V MACRO FORMAT ERROR An attempt was made to store a macro while storing another macro
using a U or V macro.
A V macro was specified although the processing to store a macro
was not in progress.
A U macro number and V macro number do not correspond with
each other.
4532 IMPROPER U/V MACRO NUMBER The number of an inhibited macro (number beyond the range from 01
to 99) was specified in a U or V macro command.
4533 U/V MACRO MEMORY OVERFLOW An attempt was made to store too many macros with a U or V macro
command.
4534 W MACRO NUMBER NOT FOUND Macro number W specified in a U or V macro command is not stored.
4535 U/V MACRO NESTING ERROR An attempt was made to call a macro which is defined three times or
more using a U or V macro command.
An attempt was made to store 15 or more macros in the storage area
for macros of number 90 to 99.
4536 NO W, Q COMMAND IN
MULTI-PIECE
W or Q was not specified in the command for taking multiple workpieces
(G73, G74).
4537 ILLEGAL Q VALUE IN MULTI-PIECE In the command for taking multiple workpieces (G73, G74), Q is set to
a value beyond the range from 1 to 4.
4538 W NO. NOT FOUND IN
MULTI-PIECE
Macro number W specified in the command for taking multiple work-
pieces (G73, G74) is not stored.
4539 MULTI-PIECE SETTING IS ZERO The command for taking multiple workpieces (G73, G74) was specified
although zero is specified for the function to take multiple workpieces
(No. 16206 or signals MLP1 and MLP2 (PMC address G231, #0 and
#1)).
4540 MULTI-PIECE COMMAND WITHIN
MACRO
The command for taking multiple workpieces (G73, G74) was specified
when a U or V macro was being stored.
4542 MULTI-PIECE COMMAND ERROR Although G98P0 was specified, the G73 command was issued.
Although G98K0 was specified, the G74 command was issued.
