Calculation error during the processing of the geometry definition containing arbitrary angle commands.
Object
SYSTEM
Code
XYY
YY:
bit0->Overflow in converting into integer
bit1->Exponential underflow
bit2->Exponential overflow
bit3->Calculation of root of a negative number
bit5->Angle overflow for SIN, COS, TAN and COT
X:
1->Calculation of coefficient of the line (first line) which passes the point commanded in the previous sequence and makes an angle of “A” deg. to Z-axis
2->Calculation of coefficient of the line (first line) which passes the point commanded in the present sequence and the one commanded in the previous sequence
3->Calculation of coefficient of the line (second line) which passes the point commanded in the present sequence and the one commanded in the sequence to be executed next
4->Calculation of coefficient of the line (second line) passing the point commanded in the sequence to be executed next and makes an angle of “A” deg. to Z-axis.
5->Calculation of coefficient of the line (second line) which passes the point commanded in the present sequence and makes an angle of “A” deg. to Z-axis.
6->Calculation of the commanded point (the point of intersection of the first and the second lines) for the sequence containing only A command.
Probable Faulty Locations
Program error
Measures to Take
Check the contents of error in the program from the alarm code number; remove the cause which intervenes the execution of arbitrary angle chamfering command.
