From command end position to compensation center
#5 CAV Specifies operation to be performed when an interference check has
detected the occurrence of interference (overcutting) .
0: An alarm (PS0272) is issued, and machining is stopped
(interference check alarm function) .
1: The tool path is changed to avoid interference (overcutting) , and
machining is continued (interference check avoidance function) .
For the method of interference check, see the descriptions of bit 1
(CNI) of parameter No. 6001 and bit 6 (CAV) of parameter No. 6001.
#6 NAA If the interference check avoidance function judges that the avoidance
operation will be dangerous or that further interference will occur for
the interference avoidance vector, the following action takes place:
0: An alarm is issued.
If the avoidance operation is determined to be dangerous, alarm
PS0278 is issued.
If further interference for the interference avoidance vector is
determined, alarm PS0279 is issued.
1: The avoidance operation will continue without issuing any
alarm.
NOTE
Normally, this bit should be set to 0.
#7 NAG In the interference check/avoidance function of cutter compensation,
when the length of the gap vector is 0:
0: An avoidance operation is performed.
1: No avoidance operation is performed.
