2.6 Block search Type 5 SERUPRO
2.6.8.4 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 under SERUPRO there are only some, i.e., not all, leading axes, the simulation is
3. Axes that have only one encoder from the point of view of the NCK and are operated with
Caution
In order to be able to simulate couplings correctly, the couplings must have been
switched off previously.
This can occur with machine data MD10708 $MA_SERUPRO_MASK.
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
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!
Reaching simulated target point for LEAD with JOG
At the time of "Search target found", the coupling is already active, especially for the JOG
movements. If the target point is not reached, SERUPRO approach can be used to traverse
the following axis with active coupling and an overlaid motion to the target point.
