Cause:
Axis 5 is 0 during Cartesian motion.
Troubleshooting:
Check whether the axis 5 position is 0.
Solution:
If this error occurs during Cartesian jogging, switch to joint jogging and jog axis 5 away from its 0 position.
Case sharing:
Lin(ap0)
If the joint values of ap0 are (10,0,20,10,0,0)
then running this statement reports an axis 5 singularity error.
