Straight line LP
The electrode moves in a straight line from its current position to the
straight-line end point. The starting point is the end point of the
preceding block.
8 Polar coordinates radius PR : Enter the distance
from the pole CC to the straight-line end point.
8 Polar coordinates angle PA : Angular position of the
straight-line end point between –360° and +360°.
The sign of PA depends on the angle reference axis:
„ Angle from angle reference axis to PR is counterclockwise: PA>0
„ Angle from angle reference axis to PR is clockwise: PA<0
