Master value coupling - 840D sl only

8.3.1

Product brief

8.3.1.1

Function

The "axial master value coupling" function can be used to process short programs cyclically
with close coupling of the axes to one another and a master value that is either generated
internally or input from an external source.
The master value can, for example, be derived from a conveyor belt or a vertical shaft.
The axial master value coupling can be switched on and off in the NC part program or via
synchronized action.
8.3.1.2

Preconditions

The option "Master Value Coupling and Curve Tables Interpolation" or the relevant option of
generic coupling (refer to " Preconditions (Page 368) " in the "Brief description" for generic
coupling) is a prerequisite for utilization of the function.
8.3.2

General functionality

Curve table
With the axial master value coupling, a leading and a following axis are moved in synchronism.
It is possible to assign the position of the following axis via a curve table or the resulting
polynomial uniquely to a position of the leading axis - simulated if necessary.
Master value object
The master value object is the input variable for the curve table.
The following can be defined as the position of the master value object:
● The axis actual position (actual value measured by transmitter)
or
● The setpoint position (calculated from interpolator) (default)
If the leading axis is interpolated by the same NCU, the setpoint coupling delivers a better
follow-up response than is possible for actual value coupling (in the same IPO cycle).
