Number ContentsMessage
4026 COMMUNICATION ERROR An overrun, parity, or framing error occurred during read via the interface
of the teaching box.
The number of the input data bits is incorrect, or the set baud rate or I/O
device specification number is illegal.
4027 DR SIGNAL OFF The I/O device operation ready signal (DR) is off when data is input or
output via the interface of the teaching box.
The power to the I/O device may be off, or there may be a cable discon-
nection or a printed circuit board failure.
4028 BUFFER OVERFLOW During data read via the interface of the teaching box, although a read
operation is stopped, input continues even after ten characters have
been input. The I/O device or printed circuit board is faulty.
4031 MIRROR AXIS PRM. SETTING
ERROR
For the mirror axis under constant optical path control, the following pa-
rameters are not set:
Bit 0 of parameter No. 7052 = 1, bit 1 of parameter No. 2005 = 0, bit 7
of parameter No. 1819 = 1, bit 0 of parameter No. 6131 = 0, parameter
No. 7510 = 2
4032 APPROACH TIME ERROR Because the value set in parameter No. 15782 is too large, the ap-
proach operation feedrate cannot be controlled at the time of beam out-
put. Set a smaller value than the piercing time (parameter No. 15087)
in parameter No. 15872.
4033 Z AXIS PRM. ERROR For the Z–axis, the following settings are not made: Bit 5 of parameter
No. 1806 = 1, bit 1 of parameter No. 2224 = 1
4700 PROGRAM ERROR (OT +) The value specified in the X-axis move command exceeded the posi-
tive value of stored stroke limit 1. (Advance check)
4701 PROGRAM ERROR (OT –) The value specified in the X-axis move command exceeded the neg-
ative value of stored stroke limit 1. (Advance check)
4702 PROGRAM ERROR (OT +) The value specified in the Y-axis move command exceeded the posi-
tive value of stored stroke limit 1. (Advance check)
4703 PROGRAM ERROR (OT –) The value specified in the Y-axis move command exceeded the neg-
ative value of stored stroke limit 1. (Advance check)
4704 PROGRAM ERROR (OT +) The value specified in the Z-axis move command exceeded the posi-
tive value of stored stroke limit 1. (Advance check)
4705 PROGRAM ERROR (OT –) The value specified in the Z-axis move command exceeded the neg-
ative value of stored stroke limit 1. (Advance check)
5000 ILLEGAL COMMAND CODE The specified code was incorrect in the high–precision contour con-
trol (HPCC) mode.
5003 ILLEGAL PARAMETER (HPCC) The parameter setting is incorrect.
5004 HPCC NOT READY High–precision contour control is not ready.
5006 TOO MANY WORD IN ONE BLOCK The number of words specified in a block exceeded 26 in the HPCC
mode.
5007 TOO LARGE DISTANCE In the HPCC mode, the machine moved beyond the limit.
5009 PARAMETER ZERO (DRY RUN) The maximum feedrate (parameter No. 1422) or the feedrate in dry
run (parameter No. 1410) is 0 in the HPCC model.
5010 END OF RECORD The end of record (%) was specified.
5011 PARAMETER ZERO(CUT MAX) The maximum cutting feedrate (parameter No. 1422) is 0.
5012 G05 P10000 ILLEGAL START UP
(HPCC)
G05 P10000 has been specified in a mode from which HPCC mode
cannot be entered.
5013 HPCC:CRC OFS REMAIN AT
CANCEL
G05P0 has been specified in G41/G42 mode or before cancellation
axis is not found.
5014 TRACE DATA NOT FOUND Trace data is not available, preventing transfer from being performed.
5016 ILLEGAL COMBINATION OF M
CODE
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.
5020 PARAMETER OF RESTART
ERROR
The parameter for specifying program restart is not set correctly.
