Example of coordinated movements of real and virtual axes:
 Absolute position of virtual axis = 5.0
 The virtual axis is moved to position 8.0.
 Resulting virtual offset (virtOffset) at the end of movement = 3.0.
The following variables coordinate the movements of the real and virtual
axes. The nominal position value of the virtual axes is added to the nominal
position value of the real axis (feedforward of nominal value). This applies
only to the relative movements of the virtual axis.
virtOffsValid Validity of the value in virtOffset.
True: virtOffset is effective.
virtOffset Value of the relative movement of the virtual axis. (Only
important for real axes.)
virtOffsActive =
true
The feedforward of the nominal position value is
configured and effective. (Only important for virtual
axes.)
virtStartPos Starting position of the virtual axis before feedforward
of nominal position value is activated. (Only important
for virtual axes.)
realAxisNr Number of the real axis to which the virtual axis was
connected. (Only important for virtual axes.)
virtOffsetOn Feedforward of position value of virtual axis is active.
(Only important for real axes.)
channelNr Assignment of the axis to the channel.
