CAUTION
1 If the lower limit of the movement range is larger than the upper limit,
alarm PS5459 occurs when G53.1 is specified.
2 If no "computed angle" is found within the movement range because
the range is too small, alarm PS5459 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 rotary axis rollover function or rotary axis control function is
used (in which case, set parameter No.1260 (amount of movement
per rotation of the rotary axis) to 360 degrees), the tool does not
move beyond 0 degree (360 degrees) (does not take the shortcut) 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 rotary axis 30.0, Table rotary axis 270.0)
Candidate 2: (Tool rotary axis 330.0, Table rotary 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, ……)
