Axis parameters
SWINBACK (P66)
This parameter indicates whether an additive coupling is being applied between axes or there are
two axes controlled by a single servo system. When having 2 axes controlled by a single servo drive,
machine parameter SWINBACK of the secondary axis indicates whether it has its own feedback
device or it uses that of the main axis it is associated with.
See "7.13 Axes (2) controlled by a single drive" on page 368.
The following examples show the various possibilities of two axes controlled by a single servo
system. In all of them, the toggling of the velocity command must be done from the PLC using the
SWITCH2 mark.
Each axis has its own feedback device.
X axis (main) SWINBACK of the X axis = 0.
Z axis (secondary) SWINBACK of the Z axis = 1.
The two axes share the same feedback device. It must be connected to the feedback connector of
the main axis.
X axis (main) SWINBACK of the X axis = 0.
Z axis (secondary) SWINBACK of the Z axis = 0.
Value Meaning
0 It assumes the feedback of the main axis.
1 It has its own feedback device.
2 It uses the feedback of the main axis, but it has its own velocity command.
10 For an additive coupling.
Default value: 0
