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 aborted with Alarm 16952

"Reset Clear/No Start". This can occur with cross-channel couplings.

3. Axes that have only one encoder from the point of view of the NCK and are operated with external data

cannot be simulated correctly. These axes must not be integrated in couplings.

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.

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!

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.

For further information about the repositioning of soupled axes, see

"Continue machining after SERUPRO search target found".
