Couplings and master-slave

Setpoint and actual value couplings
The SERUPRO operation is a program simulation in Program Test mode with which setpoint
and actual value couplings can be simulated.
Specifications for EG simulation
For simulation of EG, the following definitions apply:
1. Simulation always takes place with setpoint coupling.
2. If not all leading axes are under SERUPRO, the simulation is aborted with Alarm 16952
"Reset Clear/No Start". This can occur with cross-channel couplings.
3. Axes that have only one encoder from the NCK point of view and are moved externally,
cannot be simulated correctly. These axes must not be integrated in couplings.
Specifications for coupled axes
The SERUPRO operation simulates coupled axes always assuming that they are setpoint
couplings. In this way, the end points are calculated for all axes that are used as target points
for SERUPRO approach. The coupling is also active with "Search target found". The path from
the current point to the end point is carried out for SERUPRO approach with the active coupling.
LEADON
The following specifications apply for the simulation of axial master value couplings:
1. Simulation always takes place with setpoint coupling.
2. SERUPRO approach takes place with active coupling and an overlaid motion of the
following axis in order to reach the simulated target point.
The following axis that is moved solely by the coupling cannot always reach the target point.
In SERUPRO approach, an overlaid linear motion is calculated for the following axis to
approach the simulated point!

CAUTION
Incorrect simulation
In order to be able to simulate couplings correctly, they must have been switched off
previously.
This can be performed with machine data MD10708 $MA_SERUPRO_MASK.
