Control Response Of Plc-Controlled Axes - Siemens SINUMERIK Series Function Manual

PLC actions
Start machine axis AX1 as PLC axis via
FC 18
Withdraw controller enable for AX1:
DB31, ... DBX2.1 = 0 (controller enable)
Initiate that axial movement continues
DB31, ... DBX28.2 = 1 (continue)
Set controller enable for AX1
DB31, ... DBX2.1 = 1 (controller enable)
Initiate axial reset
DB31, ... DBX28.1 = 1 (reset)
PLC relinquishes control of AX1 to the NCK from
DB31, ... DBX28.7 = 0 (PLC controls axis)

work independently of axis.
No axial machine data are effective and a
traversing movement is not aborted.
No axial machine data are effective.
are processed during SERUPRO to simulate the
normal procedure, e.g. PLC takes over or
relinquishes control of this axis which is also
traversing via the PLC.
The PLC takes over control of the axis before the
approach block and is responsible for positioning
this axis.
has no effect and acts only on the specified PLC-
controlled axis.
