Note
Coupling factor
A coupling factor of 1 does not have to be programmed explicitly.
The direction of the tangential axis is rotated using the coupling factor of -1.
Syntax
TANG(<following axis>, <leading axis_1>, <leading axis_2>, <coupling
factor>, <coordinate system>, <optimization>)
Meaning
TANG(...):
<following axis>:
<leading axis_1>
<leading axis_2>:
