If the parameter PRI(No.19608#5)=1
If the movement ranges of rotation axes are set to the parameters No.19741 -
No.19744, the "output angles" are determined within the ranges.
Tool rotation type or table rotation type machine
<1> The "output angles" are represented by the computed rotation axis
angle pair whose slave axis (second rotation axis) moving angle is
smaller.
When the slave axis moving angle is the same
<2> The "output angles" are represented by the computed rotation axis
angle pair whose master axis (first rotation axis) moving angle is
smaller.
When the master axis moving angle is the same
<3> The "output angles" are represented by the computed rotation axis
angle pair whose slave axis (second rotation axis) angle is nearer to 0
degree (multiple of 360 degrees).
When the slave axis angle is equally near to 0 degree
<4> The "output angles" are represented by the computed rotation axis
angle pair whose master axis (first rotation axis) angle is nearer to 0
degree (multiple of 360 degrees).
Mixed type machine
<1> The "output angles" are represented by the computed rotation axis
angle pair whose tool (first rotation axis) moving angle is smaller.
When the tool moving angle is the same
<2> The "output angles" are represented by the computed rotation axis
angle pair whose table (second rotation axis) moving angle is smaller.
When the table moving angle is the same
<3> The "output angles" are represented by the computed rotation axis
angle pair whose tool (first rotation axis) angle is nearer to 0 degree
(multiple of 360 degrees).
When the tool angle is equally near to 0 degree
<4> The "output angles" are represented by the computed rotation axis
angle pair whose table (second rotation axis) angle is nearer to 0
degree (multiple of 360 degrees).
