Axes (2) controlled by a single drive
X and Z paraxial axes (moving one at a time) and communication via
Sercos, feedback included
Using the mark for the secondary axis, SWITCH2 (M5155), one can select which axis the velocity
command and feedback data transmitted via SERCOS correspond to
With SWITCH2=0, velocity command and feedback data for the X axis.
With SWITCH2=1, velocity command and feedback data for the Z axis.
Cylindrical grinder (X and Z axes)
To make the reciprocating movement (back-and-forth table swing - Z axis) independent from the
movement of the other axis (X), that movement should be controlled through the PLC execution
channel.
When a cycle controls both axes or to move the Z axis manually (jog or handwheel), the Z axis must
be controlled by the CNC.
Since an axis cannot be controlled through 2 execution channels, the CNC must be "cheated" by
calling the axis with two different names.
Although both axes may be displayed, only the Z axis (main) will displayed in this example.
Connect the Z axis feedback (main axis).
Since the two axes share the same feedback device, set the ungoverned axis as DRO so it does
not trigger the following error alarm.
The velocity command is always output through the Z axis connector (main axis).
X axis (main) Z axis (secondary)
SWITCHAX for X = 0 SWITCHAX for Z axis = 1 (X axis)
SWINBACK for X axis = 0 SWINBACK for Z axis = 0
Z Main axis. Controlled by CNC
W Secondary axis. Controlled by PLC
