Tangential control
Tangential follow-up of individual axes is supported by SERUPRO.
For further information about tangential control, see:

/FB3/ Function Manual Special Functions; T3, "Tangential Control"
If "overlaid movements" are used, only the block search via program test (SERUPRO) can
be used, since the overlaid movements are interpolated accordingly in the main run. This
applies in particular to $AA_OFF.
2.6.8.5 Axis functions
SERUPRO conditions
The special conditions for SERUPRO must be observed with axis enable, autonomous axis
operations, and axis replacement.
Axis enable
The axial IS DB31, ... DBX3.7 ("Program test axis/spindle enable") controls the axis enables
if no closed-loop controller enable is to (or can) be issued at the machine and is active only
during the program test or when SERUPRO is active.
It is possible, via the interface signal PLC → NCK
DB31, ... DBX3.7 (program test axis/spindle enable) to do this enabling. If the real servo
enable is missing during program testing or SERUPRO, the effect on the axes/spindles is as
follows:
• As soon as the simulated program run intends to move an axis/spindle, the message
"Waiting for axis enable" or "Waiting for spindle enable" is displayed and the simulation is
stopped.
• If, during a simulated movement, the VDI signal DB31, ... DBX3.7 (program test
axis/spindle enable) is canceled again, the alarm 21612: "Channel %1 axis %2 VDI signal
’servo enable’ reset during motion” is activated.
Autonomous axis operations
Autonomous singleaxis operations are axes controlled by the PLC that can also be simulated
on SERUPRO. During SERUPRO operation, as in normal operation, the PLC can take over
or give up control of an axis. If required, this axis can also be traversed using FC18. The
PLC takes over control of the axis before the approach block and is responsible for
positioning this axis. This is valid for all block search types.
