Meaning
Pole traversal
The tool center point path (linear axis) must traverse the pole on a
continuous path.
Rotation around the pole.
The tool center point path must be restricted to a positive traversing range
of the linear axis (in front of turning center).
Rotation around the pole.
The tool center point path must be restricted to a negative traversing
range of the linear axis (behind turning center).
Traversal of pole along the linear axis
State
All axes involved in the
transformation are moved
synchronously. TRANSMIT active.
Not all axes involved in the
transformation are traversed
synchronously (e.g. position axis).
TRANSMIT not active
An applied DRF (external zero
offset) does not interfere with the
operation. Servo errors may occur
close to the pole during application
of a DRF.
