When parameter PRI (No.19608#5) is 1, the movement judgements for the first
rotation axis and second rotation axis are made in reverse order.
CAUTION
1 If the lower limit of the movement range is larger than the upper limit,
alarm PS5459 occurs when G43.5 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 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) and the movement range is set between 0 and
360 degrees, the tool does not move beyond 0 degree (360
degrees), in other words, it does not take the shortcut. Also, do not
specify a negative value or a value larger than 360 degrees for the
movement range.
An example of the "movement judgement" process is given below.
Assume that a tool rotation type or table rotation type machine has rotation axis A
(master) and rotation axis B (slave) and that there are two pairs of basic computed
angles as follows:
(A θ1 degree; B φ1 degree)
(A θ2 degrees; B φ2 degrees) where θ1 ≤ θ2.
The "computed angle" is obtained from either of the following expressions: "basic
computed angle" + 360 degrees × N or "basic computed angle" - 360 degrees × N.
Assume that the current positions and movement ranges of rotation axis A (master)
and rotation axis B (slave) are as shown in the following figure.
