5448 CRC:INTERFERENCE TO
AVD.
(M series)
In the interference check evade function of
cutter compensation, a further interference
occurs for an already created interference
evade vector.
5452 IMPROPER G–CODE
(5AXIS MODE)
(M series)
A G code that cannot be specified is found.
(5–axis mode)
This alarm is issued when:
1) Three–dimensional cutter compensa-
tion (side–face offset and leading–
edge offset) is applied during cutter
compensation, or cutter compensation
is applied during three–dimensional
cutter compensation (side–face offset
and leading–edge offset).
2) A leading–edge offset of three–dimen-
sional cutter compensation is applied
during side–face offsetting of three–di-
mensional cutter compensation, or a
side–face offset of three–dimensional
cutter compensation is applied during
leading–edge offsetting of three–di-
mensional cutter compensation.
3) Tool axis direction tool length com-
pensation is applied during tool length
compensation, or tool length com-
pensation is applied during tool axis
direction tool length compensation.
4) Tool center point control is provided
during tool length compensation, or
tool length compensation is applied
during tool center point control.
5) Tool center point control is provided
during tool axis direction tool length
compensation, or tool axis direction
tool length compensation is applied
during tool center point control.
If this alarm is issued, cancel the rele-
vant mode, then specify a different
mode.
5453 NOTE: G68 IS CANCELED
(HPCC)
(M series)
When PRM5400#2 is set to 1, and a reset
does not cancel G68, this alarm is issued
at the time of program restart. To release
this alarm, press <RESET> and <CAN>.
Once this operation is performed, the alarm
will not be issued at the next restart.
5455 ILLEGAL ACC.
PARAMETER
(M series)
A permissible acceleration parameter for
optimum torque acceleration/deceleration
is incorrect. The cause is one of the follow-
ing:
1) The ratio of the deceleration rate to the
acceleration rate is below the limit.
2) The time required for deceleration to a
speed of 0 exceeds the maximum val-
ue.
NOTE HPCC designates High–Precision Contour Control. AICC desig-
nates AI Contour Control.
