CAUTION
1 If the lower limit of the movement range is larger than the upper limit,
alarm 5459 occurs when G53.1 is specified.
2 If no "computed angle" is found within the movement range because
the range is too small, alarm 5459 occurs.
3 If 0 is set for both parameters that specify the upper and lower limits
of the movement range, the tool operates assuming that there is no
range specification.
4 When the rotation axis rollover function is used (in which case, set
parameter No.1260 (amount of movement per rotation of the rotation
axis) to 360 degrees), the tool does not move beyond 0 degree (360
degrees) if the movement range is set between 0 and 360 degrees.
Also, do not specify a negative value or a value larger than 360
degrees for the movement range.
Examples
Assume that the "basic computed angles" become the following values when
G53.1 is specified after G68.2 command in mixed type machine.
Candidate 1: (Tool rotation axis 30.0, Table rotation axis 270.0)
Candidate 2: (Tool rotation axis 330.0, Table rotation axis 90.0)
The "basic computed angles" are the "computed angles" within the range between
0 and 360 degrees. The "computed angle" is obtained from either of the following
expressions: "basic computed angle" + 360 degrees × N or "basic computed angle"
- 360 degrees × N. (N: 0, +/-1, +/-2, ……)
