Electronic Axis Coupling and Table Interpolators
Electronic axis coupling permits additional couplings to be established
between axes. From a reference axis, the
•
command position,
•
actual position 1 or
•
actual position 2 (status encoder)
can optionally be read and, according to the selected calculation mode,
multiplied by a factor, or a position offset can be taken from a writable table
and be added to the command value of the axis that is to be manipulated.
