Number Message Description
0300 ILLEGAL COMMAND IN SCALING An illegal G code was specified during scaling. Modify the
program. For the T system, one of the following functions is
specified during scaling, this alarm is generated.
- finishing cycle (G70 or G72)
- outer surface rough-cutting cycle (G71 or G73)
- end side rough-cutting cycle (G72 or G74)
- closed loop cutting cycle (G73 or G75)
- end side cutting-off cycle (G74 or G76)
- outer surface or inner surface cutting-off cycle (G75 or G77)
- multiple repetitive threading cycle (G76 or G78)
- face drill cycle (G83 or G83)
- face tap cycle (G84 or G84)
- face boring cycle (G85 or G85)
- side drill cycle (G87 or G87)
- side tap cycle (G88 or G88)
- side boring cycle (G89 or G89)
- outer surface turning cycle or inner surface boring cycle (G77
or G20)
- threading cycle (G78 or G21)
- end side turning cycle (G79 or G24)
(Specify G codes for systems B and C in that order.)
0301 RESETTING OF REFERENCE
RETURN IS INHIBITED
Although parameter No. 1012#0 (IDGx) was set to 1 to inhibit
the reference position from being set again for a return to the
reference position without a dog, an attempt was made to
perform a manual return to the reference position.
0302 SETTING THE REFERENCE
POSITION WITHOUT DOG IS NOT
PERFORMED
The reference position could not be set for a return to the
reference position without a dog. Possible causes are:
- The axis was not moved in the direction of a return to the
reference position for jog feeding.
- The axis was moved in the direction opposite to the direction
of a manual return to the reference position.
0303 REFERENCE POSITION RETURN IS
NOT PERFORMED
When the setting of a reference position at any position was
possible in Cs contour control (parameter CRF (No. 3700#0) =
1), a G00 command was issued for the Cs contour axis without
a return to the reference position after the serial spindle was
switched to Cs contour control mode.
Perform a reference position return with a G28 command before
issuing a G00 command.
0304 G28 IS COMMANDED WITHOUT
ZERO RETURN
Although a reference position was not set, an automatic return
to the reference position (G28) was commanded.
0305 INTERMEDIATE POSITION IS NOT
ASSIGNED
Although a G28 (automatic return to the reference position),
G30 (return to the second, third, or fourth reference position), or
G30/1 (return to the floating reference position) command was
not issued after power-up, G29 (return from the reference
position) was commanded.
0306 MISMATCH AXIS WITH CNR/CHF The correspondence between the moving axis and the I, J, or K
command is incorrect in a block in which chamfering is
specified.
0307 CAN NOT START REFERENCE
RETURN WITH MECHANICAL
STOPPER SETTING
An attempt was made to set a butt-type reference position for an
axis for which to use the function to set a reference position
without a dog.
0308 G72.1 NESTING ERROR G72.1 was specified again during G72.1 rotation copying.
0309 G72.2 NESTING ERROR G72.2 was specified again during G72.2 parallel copying.
