9.3 Axial leading value coupling (LEADON, LEADOF)
Note
This function is not available for SINUMERIK 828D!
Function
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.
The leading axis is the axis which supplies the input values for the curve table. The following
axis is the axis, which takes the positions calculated by means of the curve table.
Actual value and setpoint coupling
The following can be used as the master value, i.e., as the output values for position
calculation of the following axis:
• Actual values of the leading axis position: Actual value coupling
• Setpoints of the leading axis position: Setpoint value coupling
The master value coupling always applies in the basic coordinate system.
For the creation of curve tables, see section "Curve tables".
For the master value coupling, see /FB/, M3, Coupled-axis motion and master value coupling.
